How To Comply With A BS 8233 Noise Assessment For Planning Applications

For developers of residential projects, which includes houses, rental apartments, and hotels, a noise assessment is a key element of the planning application process. BS 8233 is a critical component that must be considered if consent is to be awarded by the local authority.

As part of the National Planning Policy Framework (NPPF), BS 8233:2014 outlines acceptable internal and external noise levels for habitable areas, specifically bedrooms, living rooms, dining rooms, and gardens at two different times of the day: daytime (between 0700 and 2300) and night-time (between 2300 and 0700). BS 8233 also offers guidance on how sound insulation or noise reduction strategies may be used to reduce the impact of noise in new build properties.

Why Is A BS 8233 Noise Survey Required?

If a planned residential development, school, or hospital is to be sited close to transport noise, a BS 8233 noise survey report will probably be requested by the local authority. This is to assess the likely impact of noise on residents or occupants of the new buildings, both inside and outside, so that appropriate mitigating measures can be put in place.

If noise is a factor in determining whether planning consent will be granted, the local authority may request the survey at the pre-application stage of the process. Alternatively, planning permission may be conditional on the outcome of the assessment and the implementation of mitigating measures, if these are considered necessary. The BS 8233 survey is necessary to ensure that the proposed development complies with the NPPF and Noise Policy Statement for England.

How Is A Noise Survey Conducted?

A BS 8233 survey establishes a baseline measurement of the noise in the local environment from key points on the site. This allows a prediction of the future impact of noise to be gauged, with reference to BS 8233:2014.

  • The baseline noise level is measured, at different times, and acoustic calculations completed to establish the level of noise across the development.
  • Suitable mitigation measures may be recommended to reduce the impact of noise on external areas.
  • Internal noise levels are calculated to enable the fitting of sound insulation, double glazing, and ventilation, to ensure that the impact is minimised.
  • A technical report will be produced which can be supplied to the local authority by their stated deadline.
