Report No. R12.0505/DRK Broxtowe Borough Council

SUMMARY

1. At the request of Broxtowe Borough Council, Noise & Vibration Consultants Limited were commissioned to undertake an assessment of noise and provide technical advice, as required, for mitigation measures for the construction of the proposed residential development at the Hassocks Lane site located in Beeston, Nottinghamshire.

2. The aim of the assessment is to inform and guide the design of the

development such that any likely noise impact on the proposed residential dwellings is minimised and internal noise levels meet appropriate guidance.

3. To establish any likely impact from noise, it was necessary to

determine the existing noise climate at the proposed development site. In accordance with the recently removed Planning Policy Guidance 24 (“PPG24”), the baseline monitoring was carried out over a 24-hour period to establish the daytime and night-time average levels (Note: In the absence of any existing definitive planning guidance on noise, PPG24 is still referenced as advised by the EHO).

Noise Criteria:

4. To satisfy amenity requirements for any development the proposed

noise criteria reflects the guidance established within the recently removed Planning Policy Guidance 24 `Noise and Planning’ (PPG24) to meet acceptable noise levels for new dwellings.

5. Following consultation with the Local Authority Environmental Health

Officer, where there is any evidence of industrial noise we would consider the impact in accordance with BS4142: 1997.

6. According to guidance provided within PPG24, WHO and BS8233:

1999 internal noise levels within habitable rooms during night-time periods (i.e. 2300 to 0700 hours) a noise level below 30dB(A) Leq 1 hour would be appropriate. For daytime internal noise levels below 35dB(A) Leq1 hour would achieve a good to reasonable level.

7. The proposed development is for social and private residential

dwellings.

Existing Noise Climate:

8. The results of the investigations into the existing noise climate have established the following:


th May 2012


In accordance with previous planning guidance, the existing noise levels at the proposed site are shown to fall within noise exposure category NEC `A’ or `B’ during daytime periods.

For Category A: Noise need not be considered as a determining factor in granting planning permission, although the noise level at the high end of the category should not be regarded as a desirable level.

For Category B: Noise should be taken into account when determining planning applications and, where appropriate, conditions imposed to ensure an adequate level of protection against noise.

9. During night-time periods intermittent local and distant road traffic

movements dominate the noise climate and noise levels are shown to generally fall within NEC `B’. During daytime or night-time periods there was no industrial noise observed.

Construction Phase

10. During the construction phase of the development, there will be a

variety of noise sources in use at different stages and their associated activities will vary from day to day. The noisiest activities are likely to be generated during soil movements and infrastructure development at the initial stages of the development when excavators, HGVs and JCBs may be in use. Calculations of construction noise have been undertaken at the likely closest approach.

11. For the construction phase of the development we have proposed that

best practicable means and temporary localised screening of noisy construction activities is provided when these activities occur adjacent to residential property boundaries.

Noise Impact on Existing Residents

12. The impact of road traffic noise generated by the site development is

not expected to generate any significant increase on the local road network.

Amelioration of Noise Impact on Habitable Rooms at the Development

13. Calculations of internal noise levels within habitable rooms are based

on the methodology provided within BS8233: 1999 `Sound Insulation & Noise Reduction for Buildings – Code of Practice’. The noise mitigation measures proposed are aimed to achieve a `good’ design range for living rooms and bedrooms in accordance with the standard.

14. We have looked at measures to reduce noise to acceptable levels

within habitable rooms of the proposed development by introducing appropriate glazing and room ventilation systems.


th May 2012


Amelioration of Noise Impact on Private Garden areas of the Development

15. To control noise along the site boundaries where private garden areas

are adjacent to the local road network or the fire station facility, we have advised that the boundary is fitted with an acoustic screen.

16. We conclude from our detailed analysis [of the results obtained from

the land development area] that suitable attenuation measures can be adopted to ameliorate noise levels to an acceptable level according to the requirements of WHO guidance, BS8233: 199, BS4142: 1997 and the previous planning guidance provided in PPG24: 1994.

Expert Opinion

17. Taking into account the results of the noise survey, proposed type of

development and recommendations for noise mitigation (as detailed in section 7.0), it is our expert opinion that the resultant noise levels within the property would meet appropriate and reasonable guidance and noise criteria relevant to the proposed development and would therefore provide an adequate level of protection against noise for potential occupants of the building.

1.0 INTRODUCTION 1.1 At the request of Broxtowe Borough Council, Noise & Vibration Consultants

Limited were commissioned to undertake an assessment of noise and provide technical advice, as required, for mitigation measures for the construction of the proposed residential development at Hassocks Lane site located at Beeston, Nottinghamshire.

1.2 This report provides detailed information on the existing noise climate and

where appropriate, provides recommendations for amelioration measures to reduce the effect of noise on the proposed facility to an acceptable level.

1.3 This study benefits from a site noise survey and inspection, which was

carried out by Noise & Vibration Consultants Ltd on 3rd to 4th May 2012. 1.4 The assessment addresses the following issues:

• Provides information on the existing background noise levels. • Establishes the noise exposure categories (NEC) as required by PPG24:

1994. • Assesses noise from movement of existing road traffic in relation to

general noise levels and frequency content. • Provide information on any identified industrial noise source in the

vicinity of the site and where appropriate assess its impact in accordance with BS4142: 1997.

• Provides recommendations for any relevant noise mitigation measures necessary to meet appropriate noise guidance and standards within private gardens and habitable rooms.

2.0 SITE DESCRIPTION 2.1 Introduction 2.1.1 The location for the proposed residential development is situated on land at

Hassocks Lane, Beeston, Nottinghamshire. The land area is currently clear of development.

2.1.2 The site adjoins existing residential properties off Hassocks Lane (northwest

boundary) and Herald Close to the west and southwest site boundary. Adjoining the site to the northeast and east is the Royal Mail depot with commercial buildings to the southeast off Padge Road. Along the western boundary of the site is the relatively new Fire Brigade Station.

2.1.3 The landform of the site is relatively flat and access would be via an

entrance off Hassocks Lane and the service road to the Fire Station. 2.1.4 The proposed development includes for the construction of social and private

residential properties. 2.2 General Environs 2.2.1 The main source of existing noise affecting nearest proposed properties

relates to the following:

(i) Movement of local road traffic along the local road network (i.e. Hassocks Lane and Padge Road).

(ii) Noise from vehicle activities from the Royal Mail depot during the daytime and night-time periods to the northern boundary.

2.3 Design Detail 2.3.1 The report will consider issues relating to the site layout and development

design including the following:

(i) Bedroom and Living Room positions relative to the main noise source. (ii) Suitable glazing and ventilation systems. (iii) Private garden areas to protect residents from road traffic and any

identified industrial noise.



3.0 NOISE POLICY, GUIDANCE AND STANDARDS 3.1 Introduction 3.1.1 Noise has been defined as sound that is unwanted by the recipient. The

effects of noise on the neighbourhood are varied and complicated, including such things as interference with speech communication, disturbance of work, leisure or sleep. A further complicating factor is that in any one neighbourhood some individuals will be more sensitive to noise than others.

3.1.2 In 2000, BRE conducted a national study of environmental noise levels for

the Department of the Environment (`The National Noise Incidence Study 2000’: DEFRA Feb 2002). The study found that 55 (+/- 3%) of the population of England and Wales live in dwellings exposed to day-time noise levels above the WHO level of 55dB LAeq,day. It also found that 63 (+/- 3%) of the population were exposed above the level of 45dB LAeq,night.

Planning Guidance

3.1.3 The Government has recently removed the existing Planning Policy Guidance

on noise, which was known as PPG24: 1994. The National Framework Planning Policy, which has recently been published states “109. The planning system should contribute to and enhance the natural and local environment by:

• preventing both new and existing development from contributing to

or being put at unacceptable risk from, or being adversely affected by unacceptable levels of soil, air, water or noise pollution or land instability;”

3.1.4 The Noise Policy Statement for England (NPSE) – March 2010 has the

following long term vision in policy aims:

“Through the effective management and control of environmental, neighbor and neighbourhood noise within the context of Government policy on sustainable development; • avoid significant adverse impacts on health and quality of life • mitigate and minimise adverse impacts on health and quality of life; and • where possible, contribute to the improvement of health and quality of

life. 3.1.5 Having consulted the EHO at we have been advised that we should still

consider PPG24 guidance and continue to make reference to the existing British Standards on noise relative to industrial noise and internal room design criteria (i.e. BS8233: 1999 and BS4142: 1997).

3.1.6 Within the introduction of the previous Planning Policy Guidance PPG24:

1994 `Planning and Noise' the Department of the Environment gives advice about noise and stated that:



3.1.7 “The aim of this guidance is to provide advice on how the planning system

can be used to minimise the adverse impact of noise without unreasonable restrictions on development or adding unduly to the costs and administrative burdens of business.”

3.1.8 The guidance introduces the concept of Noise Exposure Categories (NEC) for

the assessment of the suitability of sites affected by transportation noise. The NEC procedure is only applicable for the introduction of a new residential development into an area with an existing noise source. At Annex 3 guidance is given for various types of noise sources, which include commercial developments, road traffic, aircraft and railways.

3.1.9 For reference, the recommended noise exposure categories for new

dwellings near existing sources are shown below in Table 3.1. Note that these noise categories are based on measurements taken in an open site (i.e. without any proposed noise attenuating features in place).

0 Noise Levels: the noise level(s) (LAeq,T) used when deciding the NEC of a site should be representative of typical conditions.

1 Night time noise levels (2300-0700 hrs): sites where individual noise events regularly exceed 82dB

LAmax (S time weighting) several times in any hour should be treated as being in NEC C, regardless of the LAeq,8hr (except where the LAeq,8hr already puts the site in NEC D).

3.1.10 The night-time level of 45dB L Aeq,8 hour

is based on achieving an internal noise

level of 30-35dB L Aeq,8 hour

with a bedroom window open, which is defined as

providing an attenuation of 10-15dB(A) [Ref.: Annex 2 of PPG 24]. On the basis of the explanation of this criterion the daytime noise criterion of 55dB

LAeq,16hour must therefore assume achieving an internal noise level of 40-45dB

LAeq,16hour.



3.1.11 In applying these noise exposure categories, it states:

"Traditionally, different indices have been used to describe noise from different sources, and limits have been set over different time periods. This has caused confusion, and a move towards consistency has been made here by expressing all noises of L

07.00."

Aeq,T

over the periods 07.00-23.00 or 23.00-

3.1.12 The level at the boundary of NEC A and NEC B is based on guidance

provided by the WHO health criteria from 1980 that “general daytime outdoor noise levels of less than 55dB(A) Leq are desirable to prevent any significant community annoyance”.

3.1.13 The night-time noise level at the boundary of NEC A and NEC B is also based

on the WHO health criteria, which states that “based on limited data available, a level of less than 35 dB(A) is recommended to preserve the restorative process of sleep”.

3.1.14 The following table gives an interpretation of the NEC categories in terms of

granting planning permission.

Table 3.2: NEC Category description in terms of planning issues NEC Category

Description

A Noise need not be considered as a determining factor in granting planning permission, although the noise level at the high end of the category should not be regarded as a desirable level.

B Noise should be taken into account when determining planning applications and, where appropriate, conditions imposed to ensure an adequate level of protection against noise.

C Planning permission should not normally be granted. Where it is considered that permission should be given, for example because there are no alternative quieter sites available, conditions should be imposed to ensure a commensurate level of protection against noise.

D Planning permission should normally be refused.

Existing Guidance on Acceptable Internal Room Noise Levels, Environmental and Industrial Noise

BS 8233:1999

3.1.15 The British Standard BS8233: 1999, `Sound insulation and noise reduction

for buildings – Code of Practice’ provides additional guidance on noise levels within buildings. These are based on the WHO recommendations and the criteria given in the standard for unoccupied spaces within residential properties include the following:



Table 3.3: BS8233: 1999 Internal noise level guidance for dwellings

Criterion Typical Situation

Design Range, LAeq, dB Good Reasonable

Reasonable conditions for sleeping and resting

Living Rooms 30 40

Reasonable conditions for sleeping and resting

Bedrooms 30 35

For a reasonable standard in bedrooms at night, individual noise events (measured with the F time-weighting) should not normally exceed 45dB LAmax

BS4142: 1997 `Method for rating industrial noise affecting mixed residential and industrial areas'

3.1.16 BS 4142: 1997 `Method for Rating industrial noise affecting mixed residential

and industrial areas’ is based on the measurement of background noise using L A90

noise measurements, compared to source noise levels measured in L Aeq

units. The differential between the two measurements; once any corrections have been applied for source noise tonality, distinct impulses etc. (i.e. the `rating’ level); determines the likelihood of complaints. If the resultant `rating’ level has a differential of +5dB(A) above background noise, then the standard says that the noise is of `marginal significance’, if the differential is +10dB(A) then `complaints are likely’. This standard is suitable for assessing fixed noise sources of an industrial nature.

3.1.17 The BS4142 standard is appropriate to fixed industrial noise sources affecting residential properties and is therefore relevant to this application. Providing noise associated with any fixed industrial noise source (at the proposed nearest residential property) is no more than 5dB(A) above background noise (measured in terms of LA90) then this would be a good indication that complaints are unlikely at the development.

World Health Organisation (WHO) Guidelines for Community Noise: April 1999

3.1.18 This document provides further updated information on noise and its affects

on the community. Within the document for noise `In Dwellings’ it states that “The effects of noise in dwellings, typically, are sleep disturbance, annoyance and speech interference. For bedrooms the critical effect is sleep disturbance. Indoor guideline values for bedrooms are 30dB LAeq for continuous noise and 45dB LAmax for single sound events. Lower noise levels may be disturbing depending upon the nature of the noise source. At night- time, outside sound levels about 1 metre from facades of living spaces should not exceed 45dB LAeq, so that people may sleep with bedroom windows open. This value was obtained by assuming that the noise reduction from outside to inside with the window open is 15dB. To enable casual conversation indoors during daytime, the sound level of interfering noise should not exceed 35dB LAeq. To protect the majority of people from being seriously annoyed during the daytime, the outdoor sound level from steady, continuous noise should not exceed 55dB LAeq on balconies, terraces



and in outdoor living areas. To protect the majority of people from being moderately annoyed during the daytime, the outdoor sound level should not exceed 50dB LAeq. Where it is practical and feasible, the lower outdoor sound level should be considered the maximum desirable sound level for new development.”

3.1.19 In 2009, the World Health Organisation published `Night Noise Guidelines

for Europe’, which it describes as an extension to the WHO `Guidelines for community noise’ (1999). It concludes that “Considering the scientific evidence on the thresholds of night noise exposure indicated by Lnight,outside as defined in the Environmental Noise Directive (2002/48/EC), an Lnight,outside of 40dB should be the target of the night noise guideline (NNG) to protect the public, including the most vulnerable groups such as children, the chronically ill and the elderly. Lnight,outside value of 55dB is recommended as an interim target for those countries where the NNG cannot be achieved in the short term for various reasons, and where policy-makers choose to adopt a stepwise approach.” The target of 40dB(A) outside would relate to an internal noise level within bedrooms of 25-30dB(A) Leq8hours.

3.2 Proposed Noise Criteria 3.2.1 Following consultation with the Local Authority, in order to meet sleep

disturbance criteria and guidance found within PPG24: 1994 and WHO we conclude that the design of the building should provide the following internal noise levels:

<=30dB(A) Leq8 hours in living rooms from 0700 to 2300 hours <=35dB(A) ) Leq16 hours in bedrooms from 2300 to 0700 hours <45dB LAmax in bedrooms from 2300 to 0700 hours

3.2.2 For any private garden areas the noise criteria would relate to an absolute

level <55dB(A) Leq16hours and where industrial noise exists, BS4142 guidance should be considered.

3.3 Construction Noise 3.3.1 For construction noise British Standard BS 5228 is the relevant standard.

This is an approved code of practice under the Control of Pollution Act and consequently there is a legal requirement for construction noise to be controlled according to the recommendations given in BS5228. The standard does not give noise limits for construction sites, but emphasis is placed on ensuring that best practical means are adopted to control noise on site.

3.3.2 Noise emission levels emanating from the site due to associated construction

works for the proposed development will vary from day to day. In order to give an indication of the probable noise levels generated by the works, the highest noise sources are considered at the closest approach. The procedures set out in British Standard, BS5228-1 2009 `Code of practice of noise and vibration control on construction and open sites', have been used to estimate construction noise levels at the nearest existing property.



3.3.3 The construction activities will include the movement of soils and construction of the new building and infrastructure. The unit used to assess construction noise is the Equivalent Continuous Sound Pressure Level, L

Aeq.. For the purpose of establishing the ‘worst case’ scenario for construction noise, calculations have been based on the resultant noise at the nearest property.

3.3.4 It must be noted that Local Authorities have statutory powers to reduce or

counteract the effects of noise from construction sites via the Control of Pollution Act 1974. The Local Authority would specify maximum noise levels.

3.4 Road Traffic Noise 3.4.1 No guidance is given in PPG24 on assessment of increased traffic noise from

existing roads as a result of traffic generated by new developments. Furthermore, noise generated by traffic on the public highway as a result of a particular development is not considered to be the responsibility of the promoter of that development. However, any change in noise levels along affected roads is relevant to future planning applications.

4.1.2 The following set-up parameters were used on the sound level meters during noise measurement:

Time Weighting: Fast Frequency Weighting: `A’ Measurement Period: 15 minutes

4.2 Calibration 4.2.1 The noise meters were calibrated with the electronic calibrator prior to

commencement and on completion of the survey. No significant drift in calibration was observed.

4.3 Survey Dates and Personnel 4.3.1 Sound pressure levels were taken at four fixed positions and spot roaming

positions on site. This enabled us to establish typical ambient noise data during typical weekday and weekend periods. Mr D. R. Kettlewell of Noise & Vibration Consultants Ltd undertook these measurements on the 3rd to 4th

May 2012. 4.3.2 Measurements were recorded over a period of 24 hours at four positions.

Data logging of LAeq, LA10, LA90 and LAmax were recorded at 15-minute intervals.

4.3.3 Position 1 was at the western site boundary opposite the fire station service

yard entrance. Position 2 was adjacent to the southwestern boundary adjacent to the fire station. Position 3 was at the northeastern boundary of the site adjacent to the Royal Mail security gate entrance. Position 4 was at the northern boundary site. See Figure 1 showing the relative monitoring positions.

4.3.4 Some additional short term noise monitoring was undertaken at other

locations for information on the variation of noise at greater distance from the site boundary for analysis. This included frequency spectra analysis for the purpose of room calculations in accordance with BS8233: 1999.



4.4 Meteorological Conditions 4.4.1 Weather details were recorded during the period of the survey and are

detailed below:

Thursday 3rd to Friday 4th May 2012 4.4.2 Generally dry conditions, overcast with occasional light rain and a light north

northeast wind (2-3m/sec). Temperature ranging from 6-8deg C. 4.4.3 The night-time period was dry, mostly cloudy, winds remaining light, variable

at 0-2m/sec. Temperature around 5-6deg C. 4.4.4 The above climatic conditions were suitable for monitoring environmental

noise levels in accordance with advice given in BS7445: 2003 `Description and measurement of environmental noise’



5.0 NOISE RESULTS AND CALCULATIONS 5.1 Introduction 5.1.1 The results of average measurements taken at the fixed monitoring

position at site are presented below in tables 5.1 to 5.2, graphs 5.1 to 5.4 and detailed measurements in Appendix 2.

5.1.2 The results of typical octave band spectra measurements are shown in

graph 5.5. 5.1.3 The LAmax measured levels from 2300 – 0700 hours showed noise levels did

not exceed the 82dB limit (i.e. free field level set in PPG24). 5.1.4 For calculation of noise levels within the rooms of the proposed dwellings,

we have used the methodology given in Tables 3 and 4 of BS 8233: 1997.

5.1.5 We have calculated the noise level the living room and bedrooms to

represent the highest likely noise levels. 5.1.6 The results of the noise prediction calculations to the most sensitive

internal Living Rooms and Bedroom positions with the recommended double glazing are presented below in Table 5.4 below.

5.1.9 To ensure that the occupants of the proposed dwellings are protected, we

have used the 16-hour noise measurements to calculate the noise level in the nearest potential living room and the 8 hour measurements for night- time in bedrooms. This assumes the double-glazing and building construction recommendations are implemented. The spectra shape shown above is used to calculate the internal noise levels.

5.1.10 For the room calculations, the following external noise levels have been used

for the predictions, based on the survey results and provisional layout drawing provided by Broxtowe Borough Council:

5.1.12 The results of the calculations show that with the proposed double glazing, ventilation and building construction measures in place, the internal noise levels would fall within acceptable noise criteria.

Industrial Noise

5.1.13 Based on observations at site during the 24-hour weekday period, there was

no evidence of any industrial noise. The Royal Mail site generates vehicle movements, which are assessed above in terms of LAeq and LAmax levels within bedrooms.



6.0 CONSTRUCTION NOISE

6.1 Introduction 6.1.1 No specific advice is provided at this stage of the development by the Local

Authority. Typical planning consent conditions relating to construction noise will be based on the application of `best practice’ in accordance with BS5228-1: 2009 and restriction on operating hours.

6.2 Construction Activities 6.2.1 Initial site preparation works is likely to involve the demolition of existing

buildings, movement of soil and the construction of infrastructure. 6.2.2 It is considered that excavators, JCB’s, dumpers, generators, concrete mixers

and asphalt spreading machines etc would be required to construct the site. 6.2.3 The above noise sources and their associated activities will vary from day to

day and may be in use at different stages of the development for relatively short durations.

6.3 Construction Noise Prediction 6.3.1 We have given below an indication of expected highest noise levels at the

nearest receptors based on soil movement and general site activities at the closest approach to existing residential areas.

6.3.2 The calculations use the calculation methodology given in BS 5228: Part 1,

2009. For this method the sound power level of the noise source is defined and the attenuation is calculated between its location and the selected receiver, taking account of distance, ground attenuation and the time that a noise source will be operating.

6.3.3 The results of calculations for soil movement and general site activities are

shown below in Table 6.1

Table 6.1: Noise Predictions for Worst Case Construction Noise Position Distance to

receptor (m) Activity Noise Level

Soil Movement Infrastructure General site activities Road Construction

50-78 50-74 47-77 50-73

Note: Construction noise prediction levels given above assume no screening attenuation and plant equipment at close approach.



6.3.4 The noise of activities during the construction of the site would vary

throughout the day and would depend on the particular work being undertaken. The highest community noise levels are likely to be created during the movement of soil when this is close to dwelling garden boundaries. This would be within the level of noise normally found to be acceptable for an activity of this type and duration. The movement of soil may be part of the initial site preparation works and it is unlikely that any other significant sources of noise would be present on the site while these activities were being carried out.

6.3.5 In accordance with BS5228, best practical means would be employed to

control the noise generation.

e.g.

� Using equipment that is regularly maintained. � Where practicable use equipment fitted with silencers or acoustic hoods. � Construction of temporary screening on boundary of site adjacent to

existing residential areas to provide some screening of plant noise sources relative to existing residential properties (i.e. properties off Hassocks Lane and Herald Close).

� Restriction of construction hours to non-sensitive times of day would normally form part of the planning consent conditions.

� Planned routing of plant onto site to avoid sensitive dwellings. � Avoiding un-necessary revving of engines, engines switched off when

not in use. � Locating plant away from sensitive boundary positions

6.3.6 The construction of site boundary screening adjacent to existing residential

properties (2m to 2.5m in height) would reduce construction noise by between 5-10dB(A).



7.0 CONCLUSIONS AND RECOMMENDATIONS 7.1 Conclusions 7.1.1 Subjective observations at site indicate that the noise climate is dominated

by intermittent road traffic noise along the northern to southeastern boundary and distant road traffic noise from the Queens Road East (A6005).

7.1.2 The results of site noise measurements show that the existing noise levels at

the nearest facade of the proposed residential dwellings would fall within the following Noise Exposure Categories:

Table 7.1: NEC Categories (refer to Appendix 3 noise maps for contours)

Position Time Period NEC Category (According to PPG24) Refer to App 3 noise maps

1 (western boundary) Daytime Night-time

A/B B

2 (south western boundary) Daytime Night-time

A/B B

3 (north eastern boundary) Daytime Night-time

A/B B

4 (northern boundary) Daytime Night-time

B B

7.1.3 Category A: “Noise need not be considered as a determining factor in granting planning permission, although the noise level at the high end of the category should not be regarded as a desirable level.”

7.1.4 Category B: “Noise should be taken into account when determining planning

applications and, where appropriate conditions imposed to ensure an adequate level of protection against noise.”

7.1.5 By applying the recommendations detailed below, we conclude that the

resultant noise levels in gardens and sensitive rooms of the proposed dwellings would be within relevant guidance and standards relating to noise.

7.2 Recommendations 7.2.1 The following amelioration measures are designed to provide additional

attenuation from the road traffic noise such that an adequate level of protection is provided.

Design Layout

7.2.2 The draft design layout places the social housing to the northern and

western boundaries, which avoids having to have private garden areas in the noisier areas of the site (i.e. adjacent to the Royal Mail site and Hassocks Lane).



Boundary Screening Measures

7.2.3 Although there are no proposed private garden areas adjacent to the

northern boundary with the Royal Mail site (i.e. social housing area), we would recommend that a solid boundary acoustic screen is incorporated to a height of 2.1 metres to provide some protection of sensitive rooms and external areas at ground level. The screen should have a minimum mass of 10kg/m2 and an example of a close-boarded screen is provided in Appendix 4 for information.

7.2.4 To protect other sensitive garden areas of the site we would also

recommend boundary screening at the following positions:

a) 2.1m high along South eastern boundary adjacent to Padge Road (refer to Figure 2)

b) 2.1m high along South western boundary adjacent to the Fire Station (refer to Figure 2)

c) Intermediate garden boundaries with standard 1.8m high close-boarded fencing.

Glazing & Ventilation

7.2.5 Our calculations of noise entering the residential rooms of the proposed

building indicate the following glazing and ventilation configurations would be required in order to meet the noise criteria:

Attenuated forced ventilation system:

7.2.15 Ventilation of the sensitive rooms identified in Table 7.2 above would require

a forced ventilation system incorporating attenuators to ensure that the internal noise criteria is achieved and noise `break-in’ from road traffic movements at night-time is controlled.

7.2.16 If a `whole-house’ ventilation system is provided, the air into the building

should be brought in from the facade facing away from the noise source (i.e. away from Royal Mail site or Padge Road) to minimise noise `break-in’.

7.2.17 The noise level from the vent opening into the rooms will need to be

reduced so that internal noise levels are maintained (i.e. achieve a noise level of approximately NR20 in the rooms). To meet this design level may require an in-duct silencer upstream and/or downstream of the fan to achieve this but the overall noise reduction may need to be higher if the in- duct fan noise is contributory. Further advice should be sought from the system provider.

7.2.18 `Whole-house’ ventilation systems are commercially available and advice can

be sought via companies providing this type of product. 7.2.19 Alternatively, there are also independent acoustic ventilation systems

available commercially to provide air into a specific room which incorporate acoustic baffles or silencers.

Top Floor Ceilings:

Plots adjacent to northern boundary and Padge Road

7.2.20 Top Floor Ceiling: 1 x 15mm layer of `Soundbloc’ plasterboard (sealed and

skimmed) to ceiling joists with minimum 250mm loft insulation above. Note: The above subject to Building Regulation Requirements applicable at the time of construction.

All other plots

7.2.21 Top Floor Ceiling: Standard construction in accordance with Building

Regulation requirements applicable at the time of construction.

All plots: 7.2.22 Walls: Cavity wall construction for example, a 100mm cavity blockwork or

similar approved insulation block in accordance with current Building Regulations.

7.3 Industrial Noise 7.3.1 There was no evidence of any industrial noise on site, the Royal Mail noise

sources related to vehicle movements and loading/unloading of vehicles.



7.4 Expert Opinion 7.4.1 Taking into account the results of the noise survey and recommendations for

noise mitigation and design layout, it is our expert opinion that the resultant noise levels within the proposed residential dwellings would meet appropriate and reasonable guidance and noise criteria relevant to the proposed development and would therefore provide an adequate level of protection against noise for potential occupants of the dwellings.

APPENDIX 1

BASIC ACOUSTIC TERMINOLOGY

Sound is produced by mechanical vibration of a surface, which sets up rapid pressure fluctuations in the surrounding air.

Sound Pressure Level is a measurement of the size of these pressure fluctuations. It is expressed in decibels (dB) on a logarithmic scale. Each 3 dB increase in sound pressure level represents a doubling of the sound energy. The threshold of hearing is approximately 0 dB.

The rate at which the pressure fluctuations occur determines the pitch or frequency of the sound. The frequency is expressed in Hertz (Hz), that is, cycles per second. The human ear is sensitive to sounds from about 20 Hz to 20,000 Hz. Although sound can be of one discrete frequency - a 'pure tone' - most noises are made up of many different frequencies.

The human ear is more sensitive to some frequencies than others, and modern instruments can measure sound in the same 'subjective' way. This is the basis of the A- weighted sound level dB(A), normally used to assess the effect of noise on people. The dB(A) weighting emphasises or reduces the importance of certain frequencies within the audible range.

Noise Measurement

The measurement of sound pressure level is only really meaningful where the level of noise is constant. In the typical industrial environment noise levels can vary widely and sometimes short duration high levels of noise are interspersed with periods of relative quiet. The most widely used means of 'averaging' the noise over a period of time is the Equivalent Continuous Sound Level. Normally written as LAeq this value takes into

account both the level of noise and the length of time over which it occurs. There are many meters available which are capable of measuring LAeq by electronic integration

over the measurement period.

The LAeq or A-weighted equivalent continuous noise level is a measure of the total noise

energy over a stated time period and includes all the varying noise levels and re- expresses as an 'average', allowing for the length of time for which each noise level was presented.

The L

An parameters are defined as the noise levels which are exceeded for n% of the

monitoring period, thus, for example, the L A90

parameter is the noise level exceeded for

90% of the 15 minute period, ie. 13.5 minutes. The L A50

parameter is the noise level

exceeded for 50% of the hourly period, i.e. 30 minutes, etc. The Lmax parameter is the

maximum RMS A-weighted noise level occurring during the measurement period.



The definition in layman’s terms is given below for terminology used in the measurement and results obtained during the survey work.

A-weighting: Normal hearing covers the frequency (pitch) range from about 20Hz to 20,000 Hz but sensitivity of the ear is greatest between about 500Hz and 5000Hz. The "A-weighting" is an electrical circuit built into noise meters to mimic this characteristic of the human ear.

Ambient noise: The totally encompassing sound in a given situation at a given time usually composed of sound from many sources near and far.

Attenuation: Noise reduction

Background noise: The general quiet periods of ambient noise when the noise source under investigation is not there.

Decibel (dB): The unit of measurement for sound based on a logarithmic scale. 0dB is the threshold of normal hearing; 140dB is the threshold of pain. A change of 1dB is only detectable under controlled laboratory conditions.

dB(A) [decibel A weighted]: Decibels measured on a sound level meter incorporating a frequency weighting (A weighting) serves to distinguish sounds of different frequency (or pitch) in a similar way to how the human ear responds. Measurements in dB(A) broadly agrees with an individual's assessment of loudness. A change of 3dB(A) is the minimum perceptible under normal everyday conditions, and a change of 10dB(A) corresponds roughly to doubling or halving the loudness of sound.

dB(C): [decibel C weighted]: Frequency weighting which does not alter low frequency octave band levels by very much compared to `A' weighting. Similar to linear reading (i.e. linear does not alter frequency spectra at all)

Frequency (Hz): The number of sound waves to pass a point in one second.

LAeq: This is a noise index used to describe the "average" level of a noise that varies

with time (T). It allows for the different sensitivities of the human ear to different frequencies (pitch), and averages fluctuating noise levels in a manner, which correlates well with human perceptions of loudness.



LA10,T: This noise index gives an indication of the upper limit or peak levels of the

fluctuating noise. It is the "A weighted" noise level exceeded for 10 per cent of the specified measurement period (T). e.g. If the measurement period was over 10 hours and the LA10 reading was say 60dB, then this means that for 1 hour out of 10 the level

went above 60dB.

LA90,T: This noise index gives an indication of the lower limit or levels of the

fluctuating noise. It is the "A weighted" noise level exceeded for 90 per cent of the specified measurement period (T). e.g. If the measurement period was over 10 hours and the LA90 reading was say 50dB, then this means that for 9 hours out of 10 the level

went above 50dB.

LAmax: This is the highest A weighted noise level recorded during a noise

measurement period.

Residual noise: The ambient noise remaining at a given position in a given situation when the noise source under investigation is not there.

Specific noise: The noise source under investigation for assessing the likelihood of complaints
