1 EXECUTIVE SUMMARY
1.1 Instruction
Impact Acoustics Ltd have been instructed by Lodge Estates to undertake a background noise survey to British Standard
8233:2014 to determine the impact of existing noise sources on the proposed accommodation scheme at 10 Winchester
Street, Basingstoke, Hampshire, RG21 7DY.
1.2 Scope of Report
The measurements will be undertaken in accordance with ISO 1996 – Part 2: 2007 to determine the existing background
noise levels and British Standard 8233:2014 will be used to determine the impact of existing traffic on the internal noise
environment within the proposed residential dwellings. This report aims to establish the following:
- Existing background noise levels within the area;
- Assess the potential internal noise levels on the proposed rooms;
- Provide specifications for the ventilation and window glazing with the proposed rooms.
1.3 Summary of Results
1.3.1 Background Noise Levels
A 144-hour background noise survey was undertaken from 26th May – 1st June 2016 at two positions (front of site and
rear of site) in order to establish the underlying background noise levels. The maximum day time levels were found to
be LAeq, 16 hour 67.2 dB and the maximum night time levels were found to be LAeq, 8 hours 68.1 dB at position 1. The maximum
day time levels were found to be LAeq, 16 hour 60.2 dB and the maximum night time levels were found to be LAeq, 8 hours 57.9
dB at position 2.
Assessment Position Date Start Date Finish Daytime LAeq Night Time LAeq
Position 1 Front 26/05/2016 01/06/2016 67.2 68.1
Position 2 Rear 26/05/2016 01/06/2016 60.2 57.9
1.4 Conclusions
Levels have been recorded and assessments made in accordance with the relevant standards. Internal criteria’s have
been set and calculations made in order to determine the minimum construction details required in order to meet the
desired level within the proposed residential dwellings and satisfy the local council’s requirements.
The development should be designed with a 4mm glass / 14mm air gap / 6mm glass double glazed windows and an
acoustic trickle vent or similarly approved; to all rooms, except the front living room on the first floor which should be
designed with a 8.4mm glass / 12mm air gap / 6mm glass and an acoustic wall ventilator MA – 3051 or similarly
approved; to ensure the internal noise levels are acceptable in terms of the assessment to British Standard 8233: 2014.

2 INTRODUCTION
Impact Acoustics Ltd have been instructed by Lodge Estates to carry out the relevant noise assessments and calculations
at 10 Winchester Street, Basingstoke, Hampshire, RG21 7DY. It is proposed that the existing building is to be converted
to residential use on the ground floor, behind the retained shop space and also the first floor offices are to be converted
to flats.
Ambient noise levels were measured between 26th May – 1st June 2016. This report by Impact Acoustics Ltd gives the
results of these measurements and an assessment in accordance with government planning guidelines and relevant
standards together with mitigation measures as required.
With regards to external ambient noise, environmental noise levels are be monitored at the site in accordance with
British Standard 7445: 2003 'Description and measurement of environmental noise assessments and calculation made
in accordance with BS 8233: 2014 Sound Insulation and Noise Reduction for Buildings Code of Practice.
BS 8233: 2014 set the following parameters as target levels that should be designed to within rooms such as Living
Rooms and Bedrooms.
Indoor ambient noise levels in spaces when they are unoccupied and privacy is also important

Calculations and assessments are therefore to be carried out in order to satisfy the above requirements of BS8233:
2014.
References and evaluations are to be made to the National Planning Policy Framework 2012 (NPPF) and the Noise Policy
Statement for England 2010 (NPSE). The purpose of this document is to include all aspects of environmental noise
within assessments i.e. environmental noise, neighbour noise and neighbourhood noise. Noise is to be considered
alongside other relevant issues relating to the site and should not be considered in isolation, according to the NPSE.

There are several key phrases within the NPSE aims and these are discussed below.
2.1 “Significant adverse” and “adverse”
There are two established concepts that are currently being applied to noise impacts, for example, by the World Health
Organisation. They are:
2.2 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 life due to the noise.
2.3 LOAEL – Lowest Observed Adverse Effect Level
This is the level above which adverse effects on health and quality of life can be detected.
Extending these concepts for the purpose of this NPSE leads to the concept of a significant observed adverse effect level.
2.4 SOAEL – Significant Observed Adverse Effect Level
This is the level above which significant adverse effects on health and quality of life occur.
It is not possible to have a single objective noise-based measure that defines SOAEL that is applicable to all sources of
noise in all situations. Consequently, the SOAEL is likely to be different for different noise sources, for different receptors
and at different times. It is acknowledged that further research is required to increase our understanding of what may
constitute a significant adverse impact on health and quality of life from noise. However, not having specific SOAEL
values in the NPSE provides the necessary policy flexibility until further evidence and suitable guidance is available.
It is understood that there will be no provision for outside living space, therefore this has not been assessed within this
technical report.
Finally, assessments and references are to be made to the World Health Organisation Night Time Noise Guidance 2009.

4 PROCEEDURE
External noise levels were recorded over a typical period and analysis date extrapolated between 07:00 hrs 26th May –
and 07:00 hrs on 1st June 2016 at positions 1 and 2 as detailed on the attached plan sketch layout.
Position 1 was located at the front façade of the site in order to capture the noise levels associated with the adjacent
pedestrianised area , position 2 was located to the rear of the site in order to capture any noise associated with the
lower noise levels and the car park area. Sample measurements were recorded over continuous 5 minute samples and
from this data the hourly LAeq daytime values have been evaluated. Sound Pressure Levels were recorded on the
following setting along with a full octave band frequency analysis measured simultaneously and between 31.5 Hz and
16.0 kHz.
Daytime 07:00 – 23:00
LAeq 1 HOUR dB LA10 1 HOUR dB
LAMAX 1 HOUR dB LA50 1 HOUR dB
LAMIN 1 HOUR dB LA90 1 HOUR dB
Night Time 23:00 – 07:00
LAeq 5 MINUTES dB LA10 5 MINUTES dB
LAMAX 5 MINUTES dB LA50 5 MINUTES dB
LAMIN 5 MINUTES dB LA90 5 MINUTES dB
Calculations have been made in accordance with BS 8233: 2014 ‘Sound Insulation and Reduction of Buildings - Code of
Practice’. Recommendations were made for any additional acoustics measures to conform to these standards.
From the downloaded recorded results, the daytime and night time periods were assessed and used within the above
calculations as LAeq 16 HOUR dB levels for daytime and LAeq 8 HOUR dB levels for night time. These are detailed within this
report. All data averaged throughout the day has been done so on a logarithmic basis to give accurate LAeq 16 Hour dB
daytime and LAeq 8 Hour dB night time noise levels.

7.13 Discussion of Results
It can be seen from the measurement data that the external noise levels have followed the expected path and remained
fairly constant throughout the day. The levels then gradually increased as the evening progressed due to the property
being in a town centre including associated commercial operations and patron noise.

8 RECOMMENDATIONS
For the purpose of this assessment, the corresponding façade levels will be used within the BS 8233: 2014 calculations
in order evaluate the worst case scenario and select the correct window specification. Therefore, in order to achieve
the required noise levels of LAeq 16 HOUR 35 dB for habitable rooms daytime and LAeq 8 HOUR 30 dB for Bedroom at night
within the proposed, the following additional acoustic measures have been calculated. It should be noted that the
calculations have been made with the proposed windows closed. Additional calculations were made for the top floor
due to the influence of sound transmission into the various rooms via the roof / ceiling i.e. an increased impeding façade.
8.1 Calculation Procedure BS 8233: 2014

The development should be designed with a 4mm glass / 14mm air gap / 6mm glass double glazed windows and a
acoustic trickle vent or similarly approved to all rooms, except the front living room on the first floor which should be
designed with a 8.4mm glass / 12mm air gap / 6mm glass and an acoustic wall ventilator MA – 3051 or similarly approved

9 NIGHT NOISE GUIDELINES EUROPE 2009
The Night Noise Guidelines 2009 make direct reference to the World Health Organisations Guidelines for Community
Noise 1999 with recommended guideline criteria of LAeq 30 dB indoors for continuous noise. The document goes on to
explain that sleep disturbance correlates best with LAmax and effects have been observed at 42 dB or less. This is
particularly true if the background noise level is low. Noise events exceeding 42 dB(A) should therefore be limited.
It should be noted that BS 8233: 2014 makes no reference to a criteria under this British Standard to LAmax dB limits
within bedrooms at night. The aforementioned documents are Guidelines and therefore should be used for reference
purposes only.
Table 8.7 calculates an internal bedroom level at night of LAeq 8 HOUR 28.4 dB. The corresponding night time external level
of LAeq 8 HOUR 57.9 dB was calculated as detailed within this report thus giving an overall façade attenuation of 29.5 dB.
Applying this to the LAmax 42 dB level above results in an LAmax target level of LAmax 71.5 dB.
There have been several periods where this value has been exceeded within the measurement periods and therefore
given the location and enhanced glazing and ventilation, it is felt that this would be satisfactory to mitigate against noise
problems.

10 NPPF & NPSE
The National Planning Policy Framework 2012 (NPPF) and assessments to the Noise Policy Statement for England 2010
(NPSE) should be made in conjunction with each other. Paragraph 123 of the National Planning Policy Framework (NPPF)
states the following:
Planning polices and decisions should aim to:
avoid noise from giving rise to significant adverse impacts on health and quality of life as a result of new
development;
mitigate and reduce to a minimum other adverse impacts on health and quality of life arising from noise
from new development, including through the use of conditions;
recognise that development will often create some noise and existing businesses wanting to develop in
continuance of their business should not have unreasonable restrictions put on them because of changes
in nearby land uses since they were established; and
Identify and protect areas of tranquillity which have remained relatively undisturbed by noise and are
prized for their recreational and amenity value for this reason.
The Noise Policy Statement for England gives various levels of effect as detailed within this report.
With the glazing / ventilation specifications achieved within this report, the development can be implemented within
the guidelines of the aforementioned documents and ensure a development conclusion of 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 life due to the noise.

11 CONCLUSION
Levels have been recorded and assessments made in accordance with the relevant standards. Internal criteria’s have
been set and calculations made in order to determine the minimum construction details required in order to meet the
desired level within the proposed residential dwellings and satisfy the local council’s requirements.
The development should be designed with a 4mm glass / 14mm air gap / 6mm glass double glazed windows and a
acoustic trickle vent or similarly approved to all rooms, except the front living room on the first floor which should be
designed with a 8.4mm glass / 12mm air gap / 6mm glass and an acoustic wall ventilator MA – 3051 or similarly approved
to ensure the internal noise levels are acceptable in terms of the assessment to British Standard 8233: 2014.
The development does not propose external living areas and therefore an assessment to the World Health
Organisation’s ‘Guidelines for Community Noise’ has not been carried out.
This report and subsequent calculations and assessments have demonstrated that mitigation measures can be
introduced to the site in order to ensure compliance with BS 8233: 2014 for predicted internal noise levels within
dwellings.
Section 14 of the National Planning Policy Framework 2012 suggests that planning permission should be granted unless
any adverse impacts of doing so would significantly and demonstrably outweigh the benefits, when assessed against
the policies in the framework taken as a whole, or specific policies in the framework indicate the application should be
restricted.
Based on the calculations and assessments made within this report it is the professional opinion of Impact Acoustics Ltd
that the proposed development can demonstrate compliance with the National Planning Policy Framework 2012, NPPF
& NPSE and that, with regards to sound, planning permission can be granted.
