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 that 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, and preserve the acoustic amenity of these good areas
- 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, and tailor construction or renovation of the building to address noise impacts for the occupants.
