Environmental noise affects very large numbers of people throughout the world. Whatever the type of scheme, current legislation makes it necessary to be able to calculate accurately such things as:
- how much noise a new scheme will make;
- how the noise can be reduced, for example by:
- putting the scheme in a cutting;
- putting up a noise barrier;
- deciding on its length and height;
- moving the scheme to a different route;
- changing the noise-generating characteristics;
- changing the operating conditions;
- how close to build noise-sensitive developments ;
- how design self-shielding developments;
- how to create and preserve areas of quiet.
Where alternatives are being considered, it is necessary to be able to evaluate these in an objective way, for example, by calculating:
- how many people will be exposed to various levels of noise;
- whether any areas will be exposed to excessive levels of noise;
- how much noise levels and noise nuisance will change;
- economic indicators of noise impact.
NoiseMap is designed specifically to deal with all the above issues, on development schemes of all sizes and complexity, involving road, high-speed rail, metro, light rail, construction, energy and other open-air noise sources.
NoiseMap contains many tools to assist the development and testing of alternatives. This means that it can be used as an integral part of any design process, rather than merely being a post-design reporting system.
