Acoustics, acoustic, noise
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, enabling the categorisation of the site into a Noise Exposure Category (NEC). 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. The next step would be the categorisation of the site into one of four NECs (A to D).
