Planning noise survey

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: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.
