Assessment of the impact of existing noise upon a proposed residential developmentResidential planning applications focus on the existing level of noise to determine the site’s suitability for development. In general, the noise impact is assessed through monitoring at one or more locations around the development site to determine the typical daytime and night-time noise levels, which can then be assessed against relevant criteria (i.e. design guide values in BS 8233).
Specification of noise mitigation measures to be incorporated into the development design In the event that a noise impact assessment finds that the existing noise
Noise Assessment levels exceed the design criteria, mitigation measures can be included into the development design. Excess noise in external areas can often be mitigated by the installation of appropriate acoustic screening (e.g. bunds, walls of fences), or by orientating garden areas such that they are shielded from the primary noise source. Internal noise levels can be reduced through installation of enhanced double glazing or structural elements, or through the modification of internal room layouts, placing the most noise sensitive rooms away from the external noise source. Assessment of the impact of noise emitted by a proposed developmentThe noise emitted by any proposed commercial or industrial development must be given due consideration in order to protect the local amenity (generally nearby residential properties). Noise of this type is generally assessed using BS 4142 for both planning and compliance purposes. For a planning application, this involves the comparison of the predicted

Predicted Noise Levels without protection for a recent development schemenoise (based on number, type and location of noisy
activities) against the measured background noise level to determine the likely significance of effects.
The impact of noise due to construction of a proposed development Noise and vibration from construction is predicted and assessed using BS 5228, which refers to the need for the protection against noise and vibration of persons living and working in the vicinity of construction sites. It recommends procedures for noise and vibration control in respect of construction operations, including the supervision, planning, preparation and execution of works. Methods for calculating the levels of noise resulting from construction activities are provided, in addition to noise control targets, and example criteria for the assessment of the significance of noise effects.
Office to Residential Change of UseClass O of the Town and Country Planning Order 2015 permits change of use from office to residential usage subject, where determined to be necessary by the Local Authority, to the assessment of the impact of noise from commercial premises on the intended occupiers of the development. Surface has considerable experience assessing noise from commercial premises to satisfy the requirement of the order and, where appropriate, recommending mitigation measures to ensure the intended occupiers are not unreasonably impacted by existing commercial noise.
FeasibilityBy appointing Surface Acoustics to assess a site or scheme early in the development process, noise risks to future consent can be identified and minimised.
ConsultationWe undertake effective communication with councils and statutory bodies to develop concise scope of works that meet the requirements of consultees, while allowing cost-effective and timely services.
MitigationWhere existing noise issues arise, we use our technical expertise to provide innovative solutions tailored to each project.
Acoustics in Practice
DesignSurface Acoustics provide advice throughout the project life to ensure noise mitigation is incorporated as part of the ongoing design, maximising chances of consent.
AssessmentWe are experts in the measurement, modelling and data analysis of noise, and communicate our findings in clear, concise and comprehensible reports.

measured by the equipment during the survey period, including LAeq,15min, LA90,15min and LAmax,15min. Survey record sheets showing the grid reference, photographs and specific details of the monitoring location, along with the calibration certificate for the noise monitoring equipment deployed on site can be found in Appendix 1. Figure 1 shows the background sound monitoring location, and an overview of the local area.
5.1 Background Sound Survey Data Analysis Chart 1 provides a summary of the sound levels measured during the survey period, detailing LAeq,15min, LA90,15min and LAmax,15min sound levels. As can be seen, background noise levels exhibit a typical diurnal pattern, with the quietest background levels found around midnight. Chart 1: Background Sound Survey Time History
Weather conditions during the survey period were generally suitable for noise monitoring, with wind speeds less than 5 ms-1 throughout the survey period. However, some periods were found to be unsuitable due to rainfall. Such periods were identified and excluded from the data analysis process. In determining the representative background sound level for the purposes of the assessment, BS4142:2014 advises against the assumption that this can be determined from the minimum or average measured value but that it should account for the range of measured avlues. In light of this, Charts 2 and 3 present a statistical analysis of LA90,15min background noise levels recorded for daytime and night-time periods, along with the percentage of periods for which they occurred. It should be noted that the data set from which Charts 2 and 3 were derived excludes periods of rainfall as described above.
