Environmental NoiseIssue Date March 2006

This Environmental Noise information is an extract from the GIB Noise Control® Systems literature March 2006.

SPECIFIC DESIGN

The design information set out in this literature is

necessarily generalised and only applicable to normal

situations. Specific acoustic design advice should

be sought from an experienced acoustical engineer

in less common situations. For instance, inner city

apartment developments of more than 5 storeys

would usually benefit from specific design since

even minor optimisation in construction can result in

appreciable cost reductions.

Specific design is also required where a residential

development is located in a business or industrial zone

and a specified internal noise level must be achieved

for compliance with a building consent. The information

given in this publication is based on normal free flowing

traffic as the noise source and different types of noise

could change the noise reduction values given. In

particular this information should not be used where

the noise source is loud or amplified music. Specific

design is required in this case.

VARIATION IN SOUND RATINGS

The ability of building materials to resist the

transmission of sound is dependent on their density,

thickness and stiffness. Generally speaking light and

stiff materials have poor sound insulation properties

because they allow sound at certain frequencies (near

the so-called critical frequency) to transmit easily.

Materials of similar thickness and weight can have

different sound reduction performance if they have

different critical frequencies. For example, laminated

glass has a better sound reduction because it reduces

the effect of the critical frequency by damping vibration

and reducing the stiffness of the window.

MULTI-STOREY BUILDINGS

In multi-storey buildings typical of apartment

developments there are fewer transmission paths

than traditional, single occupant, single level houses.

For instance in the case of a bedroom on a mid level

there will be no significant external noise transmission

through the roof or the floor since these are shielded by

the apartments above and below.

Because there are fewer transmission paths the

overall noise reduction is greater than a house with

roof and floor paths. This factor can be included in

the design by using the partial system performances

detailed for types A, B and C construction. Thus for

the apartment with only a wall and window path the

performance is about 3 dBA higher than the overall

system performance.

Multi-storey buildings do not often use weatherboards

as an external cladding. However, 6mm fibre cement

board can be used as an equivalent to 20mm

weatherboards. It should be noted that the noise level

does not reduce significantly with height in multi-storey

buildings even up to 30 storeys and so the same

construction must be used on all levels.

WINDOW TO WALL RATIO

There is no optimum window to wall ratio. Generally

speaking, from an acoustic point of view, the smaller

the window the better as it is often the weakest

ENVIRONMENTAL NOISE

path and thicker glazing or double glazing is more

expensive in comparison to other building systems.

The newer types of laminated glazing using a PMM

interlayer (e.g. Pilkington HUSH Glass) provide about

a 3 dBA improvement over similar thickness float

glass. A 3 dBA reduction would otherwise require an

increase from 6mm to 10mm float glass.

ASSUMPTIONS IN DESIGN

The major assumption in design is that the noise

spectrum is a traffic noise spectrum. The noise

reduction may be a little more for industrial noise, which

generally has more mid to high frequency, and less for

low frequency dominated noises such as pubs or night-

clubs etc.

Another significant assumption is that windows are

perfectly sealed. This is a reasonable assumption for

aluminium joinery but a poor assumption for timber

joinery. We would not recommend standard timber

joinery for any noise reduction application above

standard construction. Also all design assumes closed

windows. Open windows will generally lower the noise

reduction to between 10 and 15 dBA.

Fibre cement board (6mm) can be used as an

equivalent to 20mm weatherboards. However, if a brick

veneer is specified a slightly higher dBA loss can be

expected.

Noise levels quoted are average levels. These are

Leq for traffic noise, Ldn for aircraft noise and L10 for

industrial noise.


ENVIRONMENTAL NOISE

Knowing the environmental noise levels for the area will determine which construction type is most suitable to achieve the indoor noise level required.

TRAFFIC NOISE

The average Leq traffic noise levels quoted in the table

below will assist in determining the likely noise levels

faced when building within a certain distance of a

particular type of road.

AIRCRAFT NOISE

Ldn noise levels quoted are the average levels for aircraft

noise. Each airport prepares a set of noise boundaries

called the Inner Control Boundary and the Outer

Control Boundary. These are based on the 65 dBA

Ldn contour and the 55 dBA Ldn contour respectively.

Outside the Outer Control Boundary no noise control

is deemed necessary. Between the Outer and Inner

Control Boundaries housing is a permitted activity but

the walls and roof of the house must provide sufficient

sound insulation to achieve a reasonable indoor noise

level. Inside the Inner Control Boundary housing is

generally a controlled or discretionary activity subject

to meeting the internal noise levels. The relevant Local

Authority sets the indoor level. The most common level

is 45 dBA Ldn. These noise levels are subject to change

from time to time. The building designer must consult

the local authority to ascertain the required indoor level

and consult the relevant planning maps to determine

the aircraft noise exposure at the proposed

building location.

INDUSTRIAL NOISE

L10 noise levels quoted are the average levels for

industrial noise. Generally when dwellings are built in

an industrial or business zoned area the building must

be built with sufficient sound insulation to reduce the

noise level inside to a reasonable level, assuming that

the industry next door is making the maximum noise

level permitted by the District Plan rules for that zone.

Often this ‘reasonable’ level will be left to the acoustic

consultant to determine. The usual indoor level used

is a level of 35 dBA for bedrooms at night and 45

dBA for other habitable spaces during the day. The

maximum noise level will vary from zone to zone and

also from Local Authority to Local Authority. Generally

the noise levels will be between 60 dBA and 75 dBA.

Zonings are subject to plan changes and the building

designer must consult the local authority to determine

the current zoning and noise rules.

Polyester Sound Control Infill Issue Date September 2017

It is acceptable to replace the specified Pink® Batts® glass wool infill in GIB Noise Control® Systems with polyester fibre infill of the same or greater thickness (if not compressed) provided the polyester manufacturer can prove it meets the minimum properties shown in the table below.

Based on testing carried out by Winstone Wallboards

in April 2017, subject to the conditions below, the

noise attenuation ratings specified in ‘GIB Noise

Control® Systems, 2017’ will be retained when

polyester fibre infill with the minimum properties listed

in the table above are substituted for either R1.2

(50mm), R1.8 (75mm) or R2.2 (90mm) Pink® Batts®

glass wool insulation of the same or greater thickness

(refer to the thickness of the Pink® Batts® specified in

the applicable GIB Noise Control® System).

In most cases GIB Noise Control® Systems also

provide Fire Resistance Ratings (FRRs). Subject to

the conditions below, substituting 100% polyester

fibre infill with the minimum properties listed in the

table above for either R1.2 (50mm), R1.8 (75mm) or

R2.2 (90mm) Pink® Batts® glass wool of the same or

greater thickness will retain the published FRRs for

these systems.

To maintain the specified STC and IIC ratings, it is

allowable to use the same thickness of polyester fibre

infill as the originally specified Pink® Batts® glass wool

infill. A greater thickness of polyester fibre infill may be

used, provided it is not compressed when installed

into the framing cavity.

The performance of any other infill product type must be

independently verified.

Conditions

— Except to the extent expressly stated in this

Testing Statement, where any substitution of

cavity infill takes place, independent verification

must be obtained to confirm that the noise control

performance of the system will be maintained.

Polyester fibre infill, and other insulation products’,

properties and characteristics may vary by

product type and manufacturer.

— It remains the responsibility of the specifier,

supplier and user to ensure compliance with the

performance and requirements in this document,

all other requirements and conditions of ‘GIB

Noise Control® Systems, 2017’, all applicable

manufacturer’s requirements, all required quality

and durability standards, and all Building Code

requirements.

Additional Two way FRR Noise Control SystemsIssue Date June 2018

Complementing the full range of systems within the GIB Noise Control Systems® literature, Winstone Wallboards has recently completed testing on an additional range of systems for both intertenancy and sub-intertenancy situations.

In addition to releasing a range of systems that utilise

a single layer of GIB® plasterboard on either side, this

release includes specific systems codes that correlate

to systems utilising GIB Toughline® and GIB Toughline®

Aqua (formerly GIB Superline®). While GIB® alternative

tables can still be used to substitute different GIB®

plasterboards within a GIB® system to gain additional

performance characteristics, we are responding to

an industry desire to have specific codes for systems

utilising specific boards.

For any further information, please contact the

GIB® Helpline on 0800 100 442.

Additional GIB Barrierline® junction details incorporating a rigid air barrier

Issue Date May 2020

It is becoming more common for terrace home designs to include a rigid air barrier. Careful consideration is required where terrace home intertenancy walls intersect with the external walls that incorporate a rigid air barrier.

Figures 1 to 8 show a number of junction details

where a GIB Barrierline® intertenancy system meets

an external wall or roof. All details incorporate GIB

Weatherline® as the rigid air barrier, solid timber or

mineral wool insulation fire stopping and include

both light and heavy wall cladding types.

For any further information, please contact the

GIB® Helpline on 0800 100 442.
