1 INTRODUCTION

1.1.1 Wardell Armstrong LLP (WA) have been instructed by Heyford Developments Ltd toundertake a noise assessment for a proposed residential development on 5.62 ha of

land off School Lane, Exhall, hereafter referred to as the ‘Site’.

1.1.2 The proposed development Site currently comprises open agricultural land. The Siteis bordered to the north by School Lane, with allotments beyond. To the east, the Site

is bordered by the newly constructed commercial premises of Red Kangaroo

Trampoline Park (RKTP) which is at commissioning stage and agricultural land, withCoventry Road and further existing industrial/commercial premises beyond. To the

south and south west, the Site is bordered by the M6 motorway and the slip road from

the A444 onto the M6, which are elevated above the surrounding ground levels. Tothe north west, the Site is bordered by open land with existing residential dwellings

and the A444 roundabout beyond.

1.1.3 The client has produced a concept masterplan (dwg. no. 27290-9032) showing the

developable area of the Site. This noise report has been prepared in support of theoutline planning application, and assesses the results of a noise survey carried out in

accordance with current guidance and includes recommendations for noise mitigation

as appropriate.

2 ASSESSMENT METHODOLODGY

2.1 Scope of Works

2.1.1 The scope of the noise assessment includes consideration of noise at sensitive areas

of the proposed development, i.e. proposed residential areas, specifically in terms of

the potential impact of existing transportation noise and any other noise sources, andis in line with current guidance.

2.2 Noise Survey

2.2.1 As part of this assessment, WA have carried out attended and unattended noisesurveys to assess the current noise levels at proposed and existing receptor locations.

2.2.2 The potential sources of noise are road traffic on School Lane, the M6 motorway, and

to a lesser extent the remainder of the local road network. In addition, future noisefrom the adjacent RKTP commercial premises, which were in the final stages of

construction during the noise survey, will also need to be considered. The noise survey

is discussed in greater detail in Section 3 of this report.

2.3 Assessment Methodology

2.3.1 The noise assessment takes into account current guidance including the following:

National Planning Policy Framework, 2012;

Noise Policy Statement for England, 2010;

Planning Practice Guidance - Noise, 2014 (PPG);

The World Health Organisation Guidelines for Community Noise 1999 (WHO);

British Standard 8233: 2014 Guidance on Sound Insulation and noise reduction forbuildings (BS8233);

Pro:PG Planning & Noise: Professional Practice Guidance on Planning and Noise(2017);

British Standard 4142:2014 Methods for rating and assessing industrial andcommercial sound (BS4142), should industrial noise be dominant at any part of

the site; and,

Department of Transport’s memorandum, “Calculation of Road Traffic Noise”(CRTN), 1998.



Page 3

National Planning Policy Framework

2.3.2 In March 2012 the ‘National Planning Policy Framework’ (NPPF) was introduced as thecurrent planning policy guidance within England. Paragraph 123 of the NPPF states:

‘Planning policies and decisions should aim to:

avoid noise from giving rise to significant adverse impacts on health andquality of life as a result of new development;

mitigate and reduce to a minimum other adverse impacts on health andquality of life arising from noise from new development, including throughthe use of conditions;

recognise that development will often create some noise and existingbusinesses wanting to develop in continuance of their business should nothave unreasonable restrictions put on them because of changes in nearbyland uses since they were established; and

identify and protect areas of tranquillity which have remained relativelyundisturbed by noise and are prized for their recreational and amenityvalue for this reason.’

2.3.3 With regard to ‘adverse impacts’ the NPPF refers to the ‘Noise Policy Statement for

England’ (NPSE), which defines three categories, as follows:

‘NOEL – No Observed Effect Level

This is the level below which no effect can be detected. In simple terms,below this level, there is no detectable effect on health and quality of lifedue to the noise.

LOAEL – Lowest Observed Adverse Effect Level

This is the level above which adverse effects on health and quality of lifecan be detected.

SOAEL – Significant Observed Adverse Effect Level

This is the level above which significant adverse effects on health andquality of life occur’.

2.3.4 The first aim of the NPSE states that significant adverse effects on health and quality

of life should be avoided. The second aim refers to the situation where the impact lies

somewhere between LOAEL and SOAEL, and it requires that all reasonable steps are



Page 4

taken to mitigate and minimise the adverse effects of noise. However, this does not

mean that such adverse effects cannot occur.

2.3.5 The Planning Practice Guidance (PPG) provides further detail about how the effect

levels can be recognised. Above the NOEL, noise becomes noticeable; however, it has

no adverse effect as it does not cause any change in behaviour or attitude. Once noisecrosses the LOAEL threshold it begins to have an adverse effect and consideration

needs to be given to mitigating and minimising those effects, taking account of the

economic and social benefits being derived from the activity causing the noise.Increasing noise exposure further might cause the SOAEL threshold to be crossed. If

the exposure is above this level the planning process should be used to avoid the effect

occurring by use of appropriate mitigation such as by altering the design and layout.Such decisions must be made taking account of the economic and social benefit of the

activity causing the noise, but it is undesirable for such exposure to be caused. At the

highest extreme the situation should be prevented from occurring regardless of the

benefits which might arise. Table 1 summarises the noise exposure hierarchy.

2.3.6 The Noise Policy Statement for England refers to the World Health Organisation

(WHO) when discussing noise impacts. The WHO Guidelines for Community Noise(1999) suggest guideline values for internal noise exposure which take into

consideration the identified health effects and are set, based on the lowest effect

levels for general populations. Guideline values for annoyance which relate toexternal noise exposure are set at 50 or 55 dB(A), representing day time levels below

which a majority of the adult population will be protected from becoming moderately

or seriously annoyed, respectively. The following guideline values are suggested byWHO:

35 dB LAeq (16 hour) during the day time in noise sensitive rooms;

30 dB LAeq (8 hour) during the night time in bedrooms;

45 dB LAf,Max during the night time in bedrooms;

50 dB LAeq (16 hour) to protect majority of population from becoming moderatelyannoyed; and

55 dBLAeq (16 hour) to protect majority of population from becoming seriouslyannoyed

2.3.7 British Standard 8233 “Guidance on sound insulation and noise reduction forbuildings” 2014 bases its advice on the WHO Guidelines. In addition, for internal noise

levels it states;

“Where development is considered necessary or desirable, despite externalnoise levels above WHO guidelines, the internal target levels may be relaxed byup to 5 dB and reasonable internal conditions still achieved.”

2.3.8 Furthermore, with regard to external noise, the Standard states;



Page 6

“For traditional external areas that are used for amenity space such asgardens and patios, it is desirable that the external noise level does notexceed 50 dB LAeq. T with an upper guidance value of 55 dB LAeq,T which wouldbe acceptable in noisier environments. However, it is also recognised thatthese guideline values are not achievable in all circumstances wheredevelopment might be desirable. In higher noise areas, such as city centresor urban areas adjoining the strategic transport network, a compromisebetween elevated noise levels and other factors, such as the convenience ofliving in these locations or making efficient use of land resources to ensuredevelopment needs can be met, might be warranted. In such a situation,development should be designed to achieve the lowest practicable levels inthese external amenity spaces, but should not be prohibited”.

2.3.9 The PPG summarises the approach to be taken when assessing noise. It accepts that

noise can override other planning concerns, but states:

“Neither the Noise Policy Statement for England nor the National PlanningPolicy Framework (which reflects the Noise Policy Statement) expects noise tobe considered in isolation, separate from the economic, social and otherenvironmental dimensions of proposed development”.

ProPG: Planning & Noise Professional Practice Guidance on Planning & Noise

2.3.10 ProPG Planning and Noise provides professional practice guidance in relation to new

residential development exposed to noise from transport sources. It providespractitioners with a recommended approach to the management of noise within the

planning system in England.

2.3.11 The guidance reflects the Government’s overarching National Planning PolicyFramework, the Noise Policy Statement for England, and Planning Practice Guidance

(including PPG-Noise) and draws on other authoritative sources of guidance. It

provides advice for Local Planning Authorities and developers, and their professional

advisors, on achieving good acoustic design in and around new residentialdevelopments.

Guidance on Assessment of Road Traffic Noise

2.3.12 The Department of Transport’s memorandum, “Calculation of Road Traffic Noise”(CRTN), 1998 defines a shortened measurement procedure which is used to calculate

the LA10,18hour noise level from a measured 3 hour period. The method requires the



Page 7

measurement of noise over 3 consecutive hours between 1000 and 1700 hours.

2.3.13 From the measured 3-hour period, the arithmetic average of the three LA10,1Hour

measurements is taken. The LA10,18Hour noise level is then determined using the

following calculation method;

LA10,18Hour = LA10,3hour - 1

2.3.14 The document “Converting the UK traffic noise index LA10,18h to EU noise indices fornoise mapping” by P G Abbott and P M Nelson (The TRL Method) provides a calculation

method to convert the calculated LA10,18Hour into a daytime LAeq as described below.

Lday = 0.95 x LA10,18hour + 1.44dB

British Standard 4142:2014 (BS4142), Method for rating and assessing industrial andcommercial sound:

2.3.15 BS4142 is used to rate and assess sound of an industrial and/or commercial nature

including:

sound from industrial and manufacturing processes;

sound from fixed installations which comprise mechanical and electrical plant andequipment;

sound from the loading and unloading of goods and materials at industrial and/orcommercial premises; and

sound from mobile plant and vehicles that is an intrinsic part of the overall soundemanating from premises or processes, such as that from forklift trucks, or that

from train or ship movements on or around an industrial and/or commercial site.

2.3.16 The standard is applicable to the determination of the following levels at outdoor

locations:

rating levels for sources of sound of an industrial and/or commercial nature; and

ambient, background and residual sound levels, for the purposes of:

1) Investigating complaints;

2) Assessing sound from proposed, new, modified or additional source(s) of sound of

an industrial and/or commercial nature; and

3) Assessing sound at proposed new dwellings or premises used for residentialpurposes.



Page 8

2.3.17 The purpose of the BS4142 assessment procedure is to assess the significance of

sound of an industrial and/or commercial nature.

2.3.18 BS4142 refers to noise from the industrial source as the ‘specific noise’ and this is the

term used in this report to refer to noise which is predicted to occur due to activities

associated with RKTP premises. The ‘specific noise’ levels, of the existing industrialpremises that have been measured are detailed in Section 4 of this report.

2.3.19 BS4142 assesses the significance of impacts by comparing the specific noise level to

the background noise level (LA90). Section 4 provides details of the background noisesurvey undertaken.

2.3.20 Certain acoustic features can increase the significance of impacts over that expected

from a simple comparison between the specific noise level and the background noiselevel. In particular, BS4142 identifies that the absolute level of sound, the character,

and the residual sound and the sensitivity of receptor should all be taken into

consideration. BS4142 includes allowances for a rating penalty to be added if it is

found that the specific noise source contains a tone, impulse and/or othercharacteristic, or is expected to be present. The specific noise level along with any

applicable correction is referred to as the ‘rating level’.

2.3.21 The greater the increase between the rating level over the background noise level, thegreater the magnitude of the impact. The assessment criteria given by BS4142 are as

follows:

A difference of around +10dB or more is likely to be an indication of a significantadverse impact, depending on the context.

A difference of around +5dB is likely to be an indication of an adverse impact,depending on the context.

The lower the rating level is relative to the measured background sound level, theless likely it is that the specific sound source will have an adverse impact or a

significant adverse impact. Where the rating level does not exceed the background

sound level, this is an indication of the specific sound source having a low impact,depending on the context.

2.3.22 During the daytime, BS4142 requires that noise levels are assessed over 1-hour

periods. However, during the night-time, noise levels are required to be assessed over15-minute periods.



Page 9

2.3.23 Where the initial estimate of the impact needs to be modified due to context, BS4142

states that all pertinent factors should be taken into consideration, including:

The absolute level of sound;

The character and level of the residual sound compared to the character and levelof the specific sound; and

The sensitivity of the receptor and whether dwellings or other premises used forresidential purposes will already incorporate design measures that secure good

internal and/or outdoor acoustic conditions.

3 NOISE SURVEYS

3.1.1 Noise surveys were undertaken on two separate occasions at six monitoring locations.

3.1.2 The monitoring locations are as follows, and are shown on Drawing Number

BM11200-023:

Monitoring Location 1 (ML1): In the western part of the Site, adjacent to the accessslip road onto the M6 south bound, at a height of 1.5m. This location was chosento measure noise from the M6 slip road which runs to the south of the proposed

development;

Monitoring Location 2 (ML2): In the adjacent land, south east of the Site, near tothe M6 motorway, at a height of 4.0m, as the ground level is lower in comparisonto the development Site. This location was chosen to measure noise from the M6;

Monitoring Location 3 (ML3): In the northern part of the Site, approximately 5mfrom School Lane, at a height of 1.5m. This location was chosen to be

representative of proposed sensitive receptors in the northern part of the Site;

Monitoring Location 4 (ML4): In the north eastern part of the Site, approximately1m from the Site boundary at a height of 1.5m. This location was chosen tomeasure external plant noise from the RKTP premises;

Monitoring Location 5 (ML5): In the northern eastern part of the Site,approximately 1m from the Site boundary and 7m north of ML4, at a height of

1.5m. This location was chosen to measure external plant noise from the RKTPpremises; and,

Monitoring Location 6 (ML6): In the north western part of the Site, approximately80m from School Lane, at a height of 1.5m. This location was chosen to measure

background noise levels in the absence of any commercial or industrial noise.

3.1.3 WA carried out a survey to assess existing ambient and background noise levels at the

proposed development Site between the 14th and 20th December 2017 and between

the 1st and 2nd of February 2018.

3.1.4 Table 2 shows the periods of unattended and attended monitoring at each location.

3.1.5 ML1, ML2 and ML3 will be used to assess road traffic noise impact on the proposedSite.

3.1.6 ML4, ML5 and ML6 will be used to assess industrial noise in section 6 of this report.

3.1.7 The noise measurements were made using Type 1, integrating sound level meters.The meters were mounted on tripods, 1.5m above the ground at 5 monitoring

locations, and 4.0m above the ground at 1 monitoring location. Each monitoring

location was more than 3.5 metres from any other reflecting surfaces. The sound level

meters were calibrated to a reference level of 94dB at 1kHz both before, and oncompletion of, the noise survey. No drift in the calibration during the survey was

noted.

3.1.8 On the 14th – 20th December 2017 the weather conditions were as follows;

Approximate average +6˚C;

Damp ground; and,

Low winds.

3.1.9 On the 1st February 2018 the weather conditions were as follows;



Page 12

Temperature approximately +4-+8˚C;

Damp ground;

80% cloud cover; and,

4-5 m/s wind.

3.1.10 On the 2nd February 2018 the weather conditions were as follows;

Temperature approximately +3-+10˚C;

Damp ground;

Clear sky; and,

4-5m/s wind.

3.1.11 For the purpose of this assessment daytime hours are taken to be 0700 to 2300 hoursand night-time hours to be 2300 to 0700 hours.

3.1.12 A-weighted1 Leqs2 were measured in accordance with the requirements of BS8233. The

maximum and minimum sound pressure levels, A-weighted L90s3 and A-weighted L10s4

were also measured to provide additional information. The measured noise levels are

set out in full in Appendix A.

3.1.13 Attended noise monitoring and a review of audio recording allows observations and

detailed notes to be made of the significant noise sources which contribute to each ofthe measured levels. The observations identified the significant noise sources at the

Site to be as follows:

Road Traffic: Noise from road traffic from the M6 and M6 southbound access slip roadto the south was audible at every monitoring location during the daytime and night-

time periods. Road traffic noise from School Lane was dominant in the northern part

of the Site during the daytime and night-time periods.

Industrial Noise: Noise from construction activities associated with the final stages of

the development of the RKTP during daytime and night-time periods was audible.

1 A’ Weighting An electronic filter in a sound level meter which mimics the human ear’s response to

sounds at different frequencies under defined conditions2 Leqs Equivalent continuous noise level; the steady sound pressure which contains an equivalent

quantity of sound energy as the time-varying sound pressure levels.3 L90 The noise level which is exceeded for 90% of the measurement period.4 L10 The noise level which is exceeded for 10% of the measurement period.



Page 13

However, investigations and consultation with a site manager demonstrated that the

activities on the site currently, are not representative of typical operations at the RKTPonce it is open. No other industrial noise sources were audible.

Aircraft: Noise from low level aircraft was audible at all monitoring locations during

the daytime and night-time periods.Other: Birdsong was audible at all locations during the daytime and night-time

periods.

3.2 Existing Noise Levels

3.2.1 The measured noise levels at ML1, ML2 and ML3 have been divided into daytime

(0700-2300 hours), and night-time (2300-0700 hours), and where applicable, have

been arithmetically averaged to give a single level for each location.

3.2.2 The results for each of the monitoring locations are presented in Table 3.

3.2.3 ML1 and ML2 were selected to represent road traffic noise from the M6 and the datahas been used to create a noise model of the potential impact of noise from the M6

and M6 and southbound access slip road, across the proposed development site.

3.2.4 ML3 has been chosen to represent road traffic noise from School Lane.

3.2.5 As detailed in Section 2.3 of this report, CRTN and TRL define a method to calculate

LA10,16Hour from three consecutive one hour measurements, taken between 1000 and

1700 hours. The assessment is shown for ML3 in Table 4.

4 SITE NOISE RISK ASSESSMENT

4.1 Introduction

4.1.1 In accordance with ProPG (2017), a Site Noise Risk Assessment (SNRA) has been

carried out. The SNRA assesses the initial risk of noise from transportation sources to

have an adverse impact on a proposed development based on the overall measuredlevels with no mitigation in place.

4.1.2 The results of noise measurements carried out during the daytime and night-time

periods are presented in Table 6, and have been compared to the informationprovided on Figure 1 of ProPG 2017.

4.1.3 Table 6 indicates that during the daytime and night-time periods, proposed receptorslocated in the southern parts of the development, near to the M6 slip road would be

at a high risk of experiencing an adverse noise impact due to road traffic.

4.1.4 Table 6 also indicates that during the night time, proposed receptors located closest

to the M6 motorway and School Lane would be at a high risk of experiencing anadverse noise impact due to road traffic.

4.1.5 ProPG states that;

‘High noise levels indicate that there is an increased risk that the developmentmay be refused on noise grounds. This risk may be reduced by following a goodacoustic design process that is demonstrated as detailed in a detailedADS(Acoustic Design Statement). Applicants are strongly advised to seek expert

advice.’

4.1.6 Table 6 indicates that during the daytime, proposed receptors located closest to theM6 motorway and School Lane would be at Medium risk of experiencing an adverse

noise impact due to road traffic.

4.1.7 ProPG states that;

‘As noise levels increase, the site is likely to be less suitable from a noiseperspective and any subsequent application may be refused unless a goodacoustic design process is followed and is demonstrated in an ADS (AcousticDesign Statement) which confirms how the adverse impacts of noise will bemitigated and minimised and which clearly demonstrated that a significantadverse noise impact will be avoided in the finished development.’

4.1.8 The Site Noise Risk Assessment shows that local noise mitigation and good acoustic

design will be required to ensure that the potential noise impact is minimised and

guideline internal and external guide line noise levels are achieved.

4.1.9 In accordance with ProPG 2017, a Stage 2 full noise assessment, which includes anacoustic design statement, is required to ensure future residents are protected and

good acoustic design has been implemented.



Page 17

5 ACOUSTIC DESIGN STATEMENT

5.1 Introduction

5.1.1 The results of the ProPG Stage 1: Initial Site Noise Risk Assessment show that receptors

in the southern and northern parts of the proposed development are likely to be at

medium to high risk of experiencing an adverse noise impact due to road traffic, withno mitigation in place.

5.1.2 A layout has been produced by the client showing the developable area of the Site

(drawing number: 27920-9302). This layout has been used in this assessment.

5.1.3 SoundPLAN noise modelling software has been used to calculate the noise levels in

the proposed developable areas in the southern part of the Site closest to the M6 and

slip roads to determine any mitigation measures.

5.1.4 The noise modelling has been checked for accuracy against the measured noise levels.

This has been carried out by co-locating a receptor location into the model with

monitoring locations. The calibration results of the model are shown against the

measured levels at ML1 and ML2, shown in Table 7.

5.1.5 Predictions have been made of noise levels at the developable area in the eastern part

of the Site closest to the M6.5.1.6 ML1 and ML2 were selected to represent road traffic noise from the M6 and the data

has been used to create a noise model of the potential impact of noise from the M6

and M6 and southbound access slip road, across the proposed development Site.

5.1.7 ML3 has been chosen to represent road traffic noise from School Lane. The noise data

from measurements at ML3 has not been used in the M6 noise model; however, the

data has been used to assess the potential impact of road traffic noise from School

Lane in the northern part of the Site.

5.2 WHO Assessment of Daytime Noise Levels in Outdoor Living Areas

5.2.1 The measured daytime noise levels, as detailed in Table 3, have been used to

determine the noise levels likely in outdoor living areas of properties in the vicinity of

road traffic noise during the daytime period.

5.2.2 The measured noise levels that are likely to impact the proposed development in the

northern and southern parts of the Site, together with the level of attenuation

required to achieve the upper guideline value of 55dB LAeq recommended in BS8233and the WHO Guidelines, during the daytime, in outdoor living areas, are summarised

in Table 8.

5.2.3 The noise levels shown in drawing BM11200-024 and Table 8 exceeds the guideline

noise level during the daytime in outdoor living areas. Therefore, mitigation measureswill be required in this part of the development to achieve the recommended

guideline noise level in outdoor living areas.

5.3 Assessment of Daytime Noise Levels in Living Rooms and Bedrooms

5.3.1 The daytime noise levels in noise sensitive rooms of the proposed dwellings have been

assessed in accordance with WHO and BS8233 guideline noise levels for living room

and bedroom areas. The guideline daytime noise level within living rooms andbedrooms is 35 dB LAeq (16hr).

5.3.2 The measured daytime noise levels have been used to determine the noise levels likely

at the facades of the properties in the vicinity of the traffic noise sources, during thedaytime period.

5.3.4 The predicted noise levels at the noise modelled facades in the southern part of the

developable area, and the calculated noise levels at the façades of the proposeddwellings in the northern part of the Site, together with the level of attenuation

required to achieve 35dB LAeq (16hr) in living rooms and bedrooms is summarised in

5.3.5 The noise levels shown in drawing BM11200-024 and Table 9 indicate that the noise

levels in noise sensitive rooms in dwellings in the northern and eastern parts of the

Site, closest to School Lane, M6 and M6 slip road, are likely to exceed noise guidancelevels with windows open during daytime periods. These dwellings will require good

acoustic design to minimise the impact of road traffic noise. This is discussed in section

5.5 of this report.

5.3.6 The facades of the buildings further into the Site will be protected by the buildings

themselves and/or be screened by other buildings. It is considered that the noise

levels at these facades, and therefore the level of attenuation the facades would needto provide to achieve recommended guideline noise values, will be less than those

detailed in Table 9.

5.4 Assessment of Night-time Noise Levels in Bedrooms

5.4.1 The guideline noise level within bedroom areas at night-time is 30dB LAeq (8hr). Inaddition, individual noise events should not normally exceed 45dB LAfmax.



Page 20

5.4.2 The measured night time noise levels have been used to determine the noise levels

likely at the facades of the properties in the vicinity of the proposed noise sensitiveparts of the development, during the night time period.

5.4.3 Before internal noise levels can be calculated 3dB(A) must be added to the free-field

measured and predicted levels to allow for the reflection of noise from the proposedhousing facades when the buildings are in place.

5.4.4 The predicted noise levels at the noise modelled facades in the southern part of the

developable area, and the calculated noise levels in the northern part of the Site atthe façades of the dwellings, together with the level of attenuation required to achieve

30dB LAeq and 45dB LAmax in the bedrooms, are summarised in Table 10.

5.4.5 The noise levels shown in drawing BM11200-025/026 and Table 10 show that the

noise levels in noise sensitive rooms in dwellings in the northern part of the Site,closest to School Lane, M6 and M6 slip road are likely to exceed noise guidance levels

with windows open during night-time periods. These dwellings will require good

those detailed in Table 10.



Page 21

5.5 Acoustic Design Process

5.5.1 Noise from M6 and associated slip road has been modelled using Soundplan 8 to showthe noise impact at proposed receptors in the southern part of the Site.

5.5.2 For the purpose of this assessment, WA has assumed locations and orientations of

dwellings based on our experience of typical homing schemes. The proposed buildingsrepresent a theoretical layout for illustrative purposes only. The theoretical layout

includes a standoff of approximately 85m from the southern boundary of the

proposed development Site, also shown in the plan provided (dwg. no. 27290-9302).

5.5.3 The theoretical layout has been used to demonstrate how the orientation of dwellings

can attenuate noise from the M6 and M6 slip road, to protect external garden areas

and dwellings further into the Site by screening noise in the southern part of the Site.

Noise Attenuation Scheme

Daytime Noise Levels in Outdoor Living Areas

5.5.4 Noise contour Drawing BM11200-027 shows the predicted external daytime noise

levels at the proposed developable area in the southern part of the Site. This includes2m high close boarded fencing located around the boundaries of all gardens, to

provide noise mitigation for outdoor living areas. The results indicate that noise levels

in proposed outdoor living areas will achieve the upper guideline level of 55dB LAeq,within the majority of gardens. However, some gardens contain small areas which

exceed 55dB LAeq.

5.5.5 Predicted noise levels in the gardens of a small number of dwelling, show anexceedance of the 55dB LAeq upper guideline value, range between 55dB(A) and

58dB(A). This indicates that noise levels in certain areas of the garden could be up to

3dB above the recommended noise level for outdoor living areas specified in BS8233.However, it is generally accepted that 3dB is the minimum change in noise level which

is just perceptible to humans. Therefore, the difference between 55dB(A) and 58dB(A)

is considered to be only just noticeable.

5.5.6 Furthermore, Drawing BM11200-027 shows that predicted noise levels in somegardens still provide an area where noise levels areas which achieve the upper

guideline value of 55dB LAeq, closest to the rear façade of houses, which are most likely

to be the area used as a patio or outdoor seating area. Therefore, elevated noise levelselsewhere in these gardens are not considered to significantly affect the amenity of

residents.



Page 22

5.5.7 The advice given in BS8233 should be a consideration when determining the

significance of noise impact in gardens associated with Plots where exceedances ofthe ‘upper guideline value’ of 55dB LAeq, 16hour, as recommended by BS8233.

5.5.8 Given the close proximity of this Site to the major transport infrastructure, any

exceedances at these plots could be considered less significant in the planningbalance.

5.5.9 It is considered that the noise levels which exceed the recommended noise levels in

areas of some gardens should be considered in the context of BS8233 guidance whenconsidering the feasibility of the proposed development Site.

5.5.10 The measured noise levels, as detailed in Table 8 and Section 5.2 of this report,indicate that mitigation measures will be required to ensure that outdoor living areasin the northern parts of the Site achieve the recommended outdoor noise guidelinevalue of 55dB LAeq.

5.5.11 To mitigate traffic noise levels in outdoor living areas located closest to, and with a

direct line of sight of School Lane, gardens could be located on the screened sides of

dwellings, i.e. not located with a direct line of sight to the road.

5.5.12 Alternatively, if gardens are to be located near to, and with a direct line of sight of,School Lane, a 15m standoff combined with standard close boarded fencing of 1.8m

in height between gardens and School Lane should be sufficient to protect external

living areas. However, it should be noted that the final height and location of noisebarriers will depend upon the final layout of the Site.

Glazing Requirements for Daytime Living Rooms and Bedrooms

5.5.13 Noise contour Drawing BM11200-028 shows the predicted daytime noise levels atfaçades of the dwellings located closest to the M6 and M6 slip road of the theoretical

layout, in the southern part of the Site.

5.5.14 When assessing daytime noise levels in noise sensitive rooms, the noise attenuationprovided by the overall building facade should be considered. To mitigate noise levels,

the composition of the building facade can be designed to provide the level of

attenuation required. Glazing is generally the building element that attenuates noise

the least, so the proportion of glazing in a building facade is an importantconsideration when assessing overall noise attenuation.



Page 23

5.5.15 In the absence of design details for the building facades, it has been assumed that the

glazing to noise sensitive rooms would comprise about 25% of the facade area. Tocalculate the overall attenuation provided by this percentage of glazing in a brick or

block facade, a non-uniform partition calculation can be used.

5.5.16 The calculation combines the different degrees of attenuation of the wall element andthe window element. A facade element comprising a standard modern solid brick or

block work construction, will typically attenuate by 45-50dB (British Standard 8233:

“Sound insulation and noise reduction for buildings – Code of practice” 1999) whereasstandard double glazing will attenuate road traffic noise by 26-29dB(A) (BRE Digest

379 “Double glazing for heat and sound insulation”). The overall noise attenuation

provided by this combination is therefore, between 31.9dB(A) and 34.9dB(A).

5.5.17 The noise attenuation requirements for proposed noise sensitive living rooms and

bedrooms in the northern and southern parts of the Site nearest to School Lane, the

M6 and M6 slip road are summarised in Table 9 and shown in drawing BM11200-028.

The requirements indicate that enhanced thermal glazing would be required to ensurethat recommended internal noise levels are met within living room and bedroom

areas with windows closed, in northern and southern parts of the Site, closest to

School Lane, the M6 and M6 slip road.

5.5.18 However, with windows open, the attenuation provided by the façade will be

approximately 15dB(A). This would potentially allow the recommended internal noise

guideline levels to be exceeded in some living rooms and bedrooms in the northernand southern parts of the Site nearest to School Lane, the M6 and M6 slip road.

5.5.19 On occasion, this may be acceptable to a resident, but when quiet conditions are

required, the resident should be able to close the windows whilst maintainingadequate ventilation. Some form of alternative ventilation would therefore need to

be installed in some of the living rooms and bedrooms.

5.5.20 Alternatively, to meet the required noise levels, living rooms and bedrooms could be

located on the screened side of the proposed buildings, away from School Lane. A 10mstandoff would provide the required attenuation to ensure that recommended

internal noise levels can be met with standard thermal double glazing, with windows

closed, within living room and bedroom areas in northern parts of the Site, closest toSchool Lane.

5.5.21 Proposed facades further into the Site will be protected by the buildings themselves



Page 24

and/or be screened by intervening buildings. These facades are likely to achieve 35dB

LAeq in living rooms and bedrooms which can be provided by standard thermal doubleglazing, even with windows open.

5.5.22 Glazing and ventilation requirements can be confirmed, on a plot by plot basis, at the

reserved matters stage.

Glazing Requirements for Night-time Bedrooms

5.5.23 Noise contour Drawings BM11200-029/030 shows the predicted night-time noise

levels at façades of the dwellings located closest to the M6 and M6 slip road of thetheoretical layout, based on the Concept Masterplan (dwg. no. 27920-9302) in the

southern part of the Site.

5.5.24 The noise attenuation requirements for proposed noise sensitive bedrooms in thenorthern and southern parts of the Site nearest to School Lane M6 and M6 slip road

are summarised in Table 10 and shown in drawing BM11200-029/030. The

requirements indicate that enhanced thermal double glazing should ensure that

recommended internal noise levels are met within bedrooms of dwellings in northernparts of the Site, closest to School Lane, M6 and M6 slip road with windows closed

during the night-time.

5.5.25 However, with windows open, the attenuation provided by the façade will beapproximately 15dB(A). This would potentially allow the recommended internal noise

guideline levels to be exceeded in some living rooms and bedrooms in the northern

and southern parts of the Site nearest to School Lane, M6 and M6 slip road.

5.5.26 Some form of acoustic ventilation would therefore need to be installed in bedrooms

located in the northern parts of the development Site. Alternatively, to meet the

required noise levels, bedrooms could be located on the screened side of theproposed buildings, away from the main source of noise.

5.5.27 A 15m standoff, combined with standard thermal double glazing, should ensure that

recommended internal noise levels are met within bedrooms of dwellings in northern

parts of the Site, closest to School Lane with windows closed during the night-time.

5.5.28 The facades of the dwellings further into the Site will be protected by the buildings


levels at these facades, and therefore the level of attenuation the facades would needto provide to achieve the required noise limits, will be less than those detailed in Table

10.



Page 25

5.5.29 Glazing requirements can be confirmed, on a plot by plot basis, at the reserved

matters stage.

5.6 Assessment of Other Relevant Issues

5.6.1 It is likely that internal and external noise guideline levels will be achieved across the

entire Site area with just local mitigation measures. Therefore, the proposeddevelopment is likely to comply with relevant national and local policy.

6 BS4142 INDUSTRIAL NOISE ASSESSMENT

6.1.1 Onsite observations indicate that there are existing industrial noise sources in thevicinity of the proposed development Site. These include the premises of RKTP located

adjacent to the north eastern part of the proposed development Site.

6.1.2 A BS4142 assessment has been carried out to assess the potential noise impact fromindustrial/commercial sources at the proposed sensitive receptors. As the

industrial/commercial noise sources on the RKTP premises have been observed to

operated continuously for 24-hours, daytime, evening and night-time periods will beused in this assessment.

Selection of the Background Noise

6.1.3 Section 8 of BS4142 provides guidance on the selection of the background sound tobe used in the assessment. BS4142 states that the background sound levels used for

the assessment should be representative of the period being assessed (i.e. daytime or

night-time periods), and that there is no “single” background sound level.

6.1.4 Therefore, some assessment of the measured noise levels is required to select themost appropriate and representative background sound level. An assessment has

been carried out based upon the measured noise levels during daytime, evening and

night-time periods.

Analysis of Background Data

6.1.5 The background noise levels used in the BS4142 assessment are the LA90 levels

measured at ML6, which were measured in the absence of noise from anyindustrial/commercial sources. The daytime and evening noise levels have been

assessed over 1-hour reference periods, and night-time noise levels assessed over 15-

minute reference periods.

6.1.6 For the purpose of this assessment, the background noise level of 62dB LA90 measured

at ML6 (over the period 1000-1100 hours) on 1st February 2018 is considered to be

typical of the background noise level during the daytime period.

6.1.7 For the purpose of this assessment, the background noise level of 61dB LA90 measuredat ML6 (over the period 2100-2300 hours) on 1st February 2018 is considered to be

typical of the background noise level during the evening period.

6.1.8 For the purpose of this assessment, the background noise level of 57dB LA90 measuredat ML6 (over the period 0000-0400 hours) on 2nd February 2018 is considered to be



Page 27

typical of the background noise level during the night time period.

6.1.9 Measurements were carried out during a representative period, and the results aretherefore considered robust.

Analysis of Existing Noise Sources

Red Kangaroo Trampoline Park

6.1.10 During the noise survey the RKTP site was at the final stages of construction before

opening. It is understood that trampoline park operates 7 days a week between 0900

hours and 2000 hours on Monday, 1600-2000 Tuesday- Thursday, 1000-2000 onFriday, 0900-2000 on Saturday and 0900-2100 Sunday. Consultation with the site

manager at the completion stage of the newly developed trampoline park, indicates

that the current external plant systems are temporary and are to be replaced withquieter systems. The site manager also stated that all deliveries will take place on the

eastern side of the premises near the site entrance, well away from the proposed

residential development land.

6.1.11 Onsite observations indicate that the only noise from RKTP which is audible on theproposed development Site, is the constant noise from two temporary external AHU

and generator plant systems, approximately 1.5m in height, and currently operational

24-hours in the south west corner of the RKTP premises. It is understood that thecurrent external units are only temporary and are to be replaced permanent systems

which are likely to have lower sound emissions. However, to ensure that the future

noise levels will be acceptable we have been assessed the current noise from the RedKangaroo Trampoline Park to establish a bench mark.

6.1.12 A noise level of 63dB LAeq was measured at ML4 between 0422 hours and 0444 hours

on 2nd February 2018. The measurement included noise from the AHU (External plant1), with the lowest contribution from other noise sources. This was measured at the

closest boundary where noise from the AHU external plant system was dominant. The

measured noise level during this period has been used for this assessment.

6.1.13 A noise level of 62dB LAeq was measured at ML5 between 0409 hours and 0419 hourson 2nd February 2018. The measurement included noise from the generator (External

Plant 2), with the lowest contribution from other noise sources. This was measured at

the closest boundary where noise from the generator was dominant. A sound powerlevel of 87dB(A) LWA was displayed on the external plant. The predicted sound pressure

level at the boundary using this reference level, is 62dB(A). The predicted sound



Page 28

pressure level is therefore identical to the measured sound pressure level during the

quiet night-time. This demonstrates that the measured level during this period issuitable for use during the day, evening and night time.

On time Correction

6.1.14 The measurement period is considered to be representative of typical operations atthe RKTP, therefore no on-time correction has been applied.

Acoustic Feature Corrections

6.1.15 BS4142 includes guidance on the application of a noise penalty which should beapplied should the industrial type noise be considered to be tonal, impulsive, or

intermittent at the proposed sensitive receptors.

6.1.16 Noise from both external plant systems is considered to contain tonal characteristicswhich are just perceptible, at adjacent proposed receptor locations. Therefore, a 2dB

penalty for tonality has been applied. No other characteristics are present in the noise;

therefore, no further noise penalties are required.

Comparison of Background and Specific Noise Levels – Daytime, Evening and Night-time

6.1.17 In accordance with BS4142, the specific night-time noise level from the

industrial/commercial premises, in the vicinity of the proposed dwellings has beencompared with the measured background noise level, shown in Table 11.

Table 11: BS4142 Assessment of industrial noise during the night-time at proposed dwellings inthe north western part of the Site (Figures in dB(A)).

6.1.18 Table 11 shows noise from the external AHU plant exceeds the background noise levelduring the daytime, evening and night-time periods by 1dB, 2dB and 6dB respectively.

This is an indication that the specific noise level is likely to have an adverse impact,

depending on the context.

6.1.19 Table 11 shows noise from the external generator plant exceeds the background noise

level during the daytime, evening and night-time periods by 0dB, 1dB and 5dB

respectively. This is an indication that the specific noise level is likely to have anadverse impact, depending on the context.

Context

6.1.20 BS4142 states that the acceptability of this level depends on the context. BS4142:2014states “The significance of sound of an industrial and/or commercial nature depends

upon both the margin by which the rating level of the specific sound sources exceeds

the background sound level and the context in which the sound occurs”.

6.1.21 The first requirement of this statement has been determined within the noise impact

assessment section above. To determine the context in which the proposed industrial

sound will reside, three factors must be considered, these are;

The absolute level of sound;

The character and level of the residual sound compared to the character and levelof the specific sounds; and,

The sensitivity of the receptor.

Absolute Level of Sound

6.1.22 The impact of a given difference between rating level and background noise level willdepend upon whether the residual sound level is low or high. Where residual sound

levels are very high, the residual sound might itself result in adverse impacts or



Page 30

significant adverse impacts, and the margin by which the rating level exceeds the

background might simply be an indication of the extent to which the specific soundsource is likely to make those impacts worse.

6.1.23 The residual noise level at the proposed development Site is high, during the daytime,

evening and night-time periods. Therefore, the exceedance level shown in Table 11becomes more significant, and the exceedance is likely to make any impacts worse.

Character and Level of Residual Sound Compared with the Specific Sound

6.1.24 The character of the residual noise during the daytime is dominated by road traffic

noise from School Lane and the M6. Road traffic contains low to mid-frequency noise,

which is similar to the character of the external plant noise from the premises of RKTP.

Therefore, the noise from external plant is likely to be less distinctive, particularlywhen at a distance from the north east Site boundary of the proposed development

Site.

6.1.25 To assess the noise levels at receptors caused by noise from the premises of RKTP, thespecific noise levels have been compared with the residual noise level taken at ML6

during the daytime, evening and night time periods. The assessment is shown in Table

12 below.

6.1.26 Noise from the premises of RKTP will exceed the residual sound level at future

receptors at the proposed development Site of between 2dB and 3dB during the

daytime. However, during the night-time, External plant 1 and 2 exceed the residualnoise level by 4dB. This is an indication that the specific noise level may cause an

adverse impact. However, it is reasonable to assume that the permanent external

plant due to replace the existing temporary external plant, will be at least 5dB(A)quieter. Therefore, this will reduce the impact of the noise from RKTP at nearest

proposed receptors to a low impact in accordance with BS4142.

Sensitivity of Receptor

6.1.27 Residential receptors are sensitive, but the sensitivity changes throughout the day,

with the evening periods being more sensitive due to the occupants’ need for quiet

for rest and relaxation.

The industrial noise from the RKTP is unlikely to have a significant impact during the

daytime. However, as stated in BS4142 Section 11.3, mitigation measures can be

incorporated, if required, to achieve a good acoustic environment in both internal and

external living areas, effectively reducing the sensitivity of the dwelling as a receptorlocation. However, it is reasonable to assume that the permanent external plant due

to replace the existing temporary external plant, will be at least 5dB(A) quieter.

Therefore, this will reduce the impact of the noise from RKTP at nearest proposedreceptors to a low impact in accordance with BS4142.

Summary of BS4142 Assessment

6.1.28 The results of the BS4142 assessment, of the existing temporary equipment, when thecontext assessment is taken into consideration, indicate that noise from the premises

of RKTP will cause an impact at proposed sensitive receptors.



Page 32

6.1.29 Details of the potential external plant systems to replace the temporary generator and

AHU currently running at the RKTP premises could not be obtained. However, it isreasonable to assume that the permanent external plant due to replace the existing

temporary external plant, will be at least 5dB(A) quieter. Therefore, this will reduce

the impact of the noise from RKTP at nearest proposed receptors to a low impact inaccordance with BS4142.

7 CONCLUSIONS

7.1 Road Traffic Noise

7.1.1 WA has carried out a noise assessment for the proposed residential development

located at Land off School Lane, Exhall, Coventry. The dominant noise source, which

would potentially affect the residents of the proposed residential development, isroad traffic on the M6, M6 slip roads and School Lane.

7.1.2 Industrial noise associated with the RKTP located adjacent to the north eastern part

of the proposed development Site is also audible.

7.1.3 Baseline noise monitoring was undertaken in addition to noise modelling using

SoundPLAN version 8.

7.1.4 WA have assumed locations and orientations of dwellings based on the providedConcept Masterplan (dwg. no. 27290-9302). The proposed buildings represent a

theoretical layout for illustrative purposes only. The theoretical layout includes a

standoff of approximately 85m from the southern boundary of the proposed

development Site.

7.1.5 The resultant noise levels can be assessed against the guideline values suggested by

the World Health Organisation. It should be remembered that the internal guideline

values are health-based and are therefore relatively inflexible; however adequatenoise mitigation is relatively straightforward to engineer. The external guideline

values are based on amenity and allow noise to be balanced against any benefits which

flow from the location of the proposed scheme.

7.1.6 Noise contour Drawing BM11200-025 shows the predicted external daytime noise

levels within proposed gardens. The results indicate that noise levels in the majority

of proposed outdoor living areas across the southern part of the Site, closest to theM6, will achieve the upper guideline level of 55dB LAeq, within the majority of garden

areas. However, some gardens contain small areas which exceed 55dB LAeq.

7.1.7 The results of the noise survey and assessment indicate that to meet the guideline

value of 55dBLAeq (16 Hour) in outdoor living areas, acoustic mitigation should be providedfor those areas located with direct line of sight to School Lane, in the northern parts

of the development.

7.1.8 Gardens could be located on the screened sides of dwellings i.e. not located with adirect line of sight to School Lane. Alternatively, it is recommended a 15m standoff



Page 34

combined with a standard close boarded fencing of 1.8m in height between gardens

and School Lane should be sufficient to protect external living areas in the northernpart of the Site.

7.1.9 The results indicate that enhanced thermal double glazing would be required to

ensure that internal noise guideline levels, are met in living rooms and bedroom areaswith a direct line of sight to School Lane and the M6 and slip road, during the daytime,

with windows closed.

7.1.10 Alternatively, to meet the required noise levels, living rooms and bedrooms could belocated on the screened side of the proposed buildings, away from School Lane. A 10m

standoff would provide the required attenuation to ensure that recommended

internal noise levels can be met with standard thermal double glazing, with windowsclosed, within living room and bedroom areas in northern parts of the Site, closest to

School Lane.

7.1.11 The results indicate that enhanced thermal double glazing will be required for

dwellings located closest to, or with a direct line of sight to School Lane and the M6and slip road, during the night-time, with windows closed.

7.1.12 A 15m standoff, combined with standard thermal double glazing, should ensure that

recommended internal noise levels are met within bedrooms of dwellings in northernparts of the Site, closest to School Lane with windows closed during the night-time.

7.1.13 With the windows open, the attenuation provided by the façade would allow the

internal daytime and night-time noise guideline levels to be exceeded in some livingroom and bedroom areas in the southern and northern parts of the development Site.

7.1.14 Acoustic ventilation would therefore need to be installed in some of the living rooms

and bedrooms located nearest to, and a direct line of sight to School Lane and the M6and slip road, during the daytime and night-time. Alternatively, to meet the required

noise levels, living rooms and bedrooms could be located on the screened side of the

proposed buildings, away from the main source of noise.

7.1.15 The requirement for glazing and acoustic ventilation will be confirmed, on a plot byplot basis at the detailed application/reserved matters stage.

7.2 Commercial/Industrial Noise

7.2.1 A BS4142 assessment has been carried out to assess the potential noise impact fromindustrial/commercial sources at the proposed sensitive receptors. The noise sources



Page 35

have been observed to be operational 24 hours. However, it is understood that the

current noise sources are only temporary but will be replaced by permanentequipment in due course. For the purpose of this assessment, the

industrial/commercial sources have been assessed during daytime, evening and night-

time periods, to establish a benchmark against which the future equipment can beassessed.

7.2.2 The results of the BS4142 assessment, when the context assessment is taken into

consideration, indicate that noise from the current external plant at the premises ofRKTP, located to the north east of the proposed development Site, will cause an

impact at the nearest proposed residential dwellings.

7.2.3 Details of the potential external plant systems to replace the temporary generator andAHU currently running at the RKTP premises could not be obtained. Therefore, it is

recommended the temporary systems are replaced with external plant systems that

cause an equal or reduced noise impact on the proposed development Site.

Furthermore, any noise penalties, for tonal, intermittent, or impulsive noise must beconsidered in the final design stage for the proposed sensitive receptors.

7.2.4 It is reasonable to assume that the permanent external plant due to replace the

existing temporary external plant, will be at least 5dB(A) quieter. Therefore, this willreduce the impact of the noise from RKTP at nearest proposed receptors to a low

impact in accordance with BS4142.

7.3 Summary

7.3.1 In policy terms, there is no presumption against development in places with high noise

levels, provided that the noise can be adequately mitigated taking into account the

economic and social benefits of the proposed scheme.

7.3.2 With the proposed mitigation measures put in place, indoor living areas are able to

meet the upper guideline limit of 55dB LAeq and therefore, meet the health based WHO

guidelines. In outdoor garden areas, with few exceptions, the 55dBLAeq (16 Hour) value is

also largely met. However, this is an amenity guideline value and therefore, the fewexceptions to meeting this value should not preclude development.
