Noise Modelling and Mapping
Noise mapping is a tool used in acoustic assessments, such as planning assessments. In this process, a proposed site and its surroundings are modelled as a 3D virtual environment. Noise sources can then be added to the noise model, either to represent existing sources such as roads and railways or proposed noise sources such as plant installations.
When is Strategic Noise Mapping Used?
Noise mapping is typically used for large or complex sites. It is particularly valuable when a large number of sources must be considered cumulatively or when complex topography or obstacles on or around a site may affect how noise propagates to different areas. Sound levels can vary significantly based on factors including weather conditions or the time of day.
When a noise-sensitive development is proposed close to multiple surrounding noise sources, it can be useful to accurately predict the effects of the sources on each façade and even each window in the development. This will ensure that all sensitive spaces are adequately protected from noise and that there are no needless over-specifications.
When proposals are to introduce noise-generating activity close to sensitive receivers, the noise map can accurately predict whether a negative impact is likely and whether mitigation should be installed. Further, it can accurately predict the most effective way to provide the required reductions, for example, the best location to place screens based on the location and heights of sound sources and receivers.
Noise mapping could be a requirement stipulated by a Local Authority or Employer, or it could be beneficial to strengthen and better represent an application.
