City Noise Mapping
SLR can predict environmental noise impacts by mapping regional or local noise, which is a combined process of Geographical Information Systems (GIS) and acoustic analysis. It involves producing a 3D model which covers a large study area, and using this model to calculate the noise impact to the surrounding population. This is a critical tool used by all levels of government to understand noise impacts and to create strategic plans, procedures and policies to mitigate any undesirable effects on the community.
Noise mapping on a city or state wide scale can provide direction to: prevent and reduce harmful environmental noise exposure; identify areas where environmental noise is good, preserve the acoustic amenity of these good areas; and provide the public access to information on environmental noise and its effects.
Detailed noise mapping allows for noise investigations to be completed at the individual building level. This helps developers, builders and home owners understand current noise levels, to tailor construction or renovation of the building to address noise impacts for the occupants.
