There are several ways in which EHPs help to control the amount of noise in the environment.  The ideal approach is to try and prevent excessive amounts of noise occurring in the first place, for example by advising on suitable noise limits when planning applications for new developments are being considered.

Where excessive noise does occur, EHP investigates and suggest solutions to the problem. In most cases, the person or business making the noise is unaware they are causing a problem.  The situation may be resolved by offering them advice on reducing the noise, or by getting them to talk with those living or working nearby to agree a mutually acceptable solution. In large perspective EHPs are working to ensure that overall levels of noise in the environment are gradually reduced.
