During the planning stage of a development, it is always necessary to assess a proposed site in accordance with National Planning Policy Framework requirements.

For this reason, a noise survey would be necessary. The noise survey would be organised in such a way so that it can encompass the simultaneous investigation of all possible noise sources (noise from road traffic, rail traffic, air traffic or a combination of noise sources).

Its duration would be 24hrs, however longer noise monitoring periods can be undertaken should it be required, in order to obtain a better statistical sample of the noise profile around the proposed development site. A vibration survey would also be undertaken should the site be close to a railway line, or any other source of vibration.

The data analysis would involve breaking down the measured time-history into daytime and night-time and calculating the corresponding average noise levels in order to better understand the acoustic identity of the proposed development site and its acoustic footprint.

We recognise that glazing specification is a very delicate procedure which can have a significant impact on the project's budget. For this reason, detailed calculations would be undertaken, based on the outcomes of the environmental noise survey, providing a pragmatic glazing specification, rather than just a "worst case scenario".

The final noise assessment report would be robust, consice and fully compliant to all requirements of current British Standards and Good Practice Documents (WHO Guidelines, BS8233, Local Authority's planning requirements).
