Planning noise survey

Planning Noise Surveys 

Once you have received the go ahead from the local authority, the developer will need to ensure all the recommendations and mitigations measures that have been proposed within the BS8233 Noise Survey Report are installed on the development. It is worth noting that once on site it is especially important to maintain a high standard of workmanship and quality control to ensure the correct execution of the acoustic detailing throughout the construction phase of the project.

BS8233 planning noise survey to new development

A planning noise survey may be required at the application stage or once planning permission has been granted. A noise survey and report are required if:

                • The proposed development with commercial areas that may create noise which may affect nearby noise sensitive properties. For example, a new commercial activity near existing residential properties.
                • The proposed development location will be sensitive to noise and is likely to be affected by existing noise sources i.e. busy roads, railway, airports or commercial activity.

A planning noise survey is undertaken to demonstrate that:

                • The source of noise is evaluated and The noise impact assessment is to demonstrate that its quantified
                • Nearby noise sensitive receptors identified
                • Noise receptors have been determined with reference to noise standards

The planning noise survey may also detail the control measures which are necessary to reduce noise to acceptable levels. For example, the installation of different glazing e.g. from double to triple glazed panels or acoustic trickle vents are installed so that internal noise standards are met.

Where the noise levels are shown as NEC category B and above, the local authority will look for noise reduction measures that will achieve the “good” internal noise level criteria in bedrooms and living rooms set out in BS8233:2014 (shown Below).  For outdoor garden areas, noise levels should be less than or equal to 55 dB(A) as recommended in the World Health Organisation Guidelines on Community Noise. Where the noise levels are shown as NEC category D, the local authority usually recommends that planning consent be refused.

There can be a large variety of scenarios and requirements that may be present during noise impact assessments, with this in mind it is important to liaise with the case officer and environmental health team, in order to ensure that the appropriate legislation and British Standards are being adhered to at all times.

Need help with your BS8233 Noise Assessment?

Then please let us know, we listen to our clients’ acoustic needs and present them with practical, cost-effective solution for BS8233 noise surveys as well the precompletion sound testing. This means that we can offer comprehensive and bespoke acoustic consultancy service. More information for BS8233 can be found here.

We use a team of highly skilled and experienced engineers along with the latest Norsonic acoustic equipment (and expert guidance) to ensure our clients are getting a high-quality service every time they decide to get in touch. For more information please check our new guidance for BS8233 noise surveys.

If you have a new development and the local authority has a BS8233 Noise Assessment, then please speak with our noise consultants today. The noise assessment process isn’t intrusive, lengthy or costly. Normally we would leave one of our class 1 sound meters over a 24-hour period, which gathers the necessary acoustic data automatically, which also considers other factors such as construction, setting and external variables. Using acoustic data, we then provide a detailed report and offer valuable advice on mitigations measures if required.

If you would like to know more about or noise impact assessment service, please contact us at or contact Darren directly on 07775 623464. Alternately if you would like more information on noise assessments then please visit our checklist page which has lots of useful information or visit our guidance for BS8233 noise surveys.
