Abstract
In order to evaluate the need for noise measures as well as the improvement that can be obtained with different measures, there is a need for a system that rates environmental noise on the basis of noise maps. Based on empirical exposure-response relationships, a rating system and a stepwise procedure for its implementation have been developed. It gives insight in the environmental noise impact on the basis of Lden or Lnight, but additionally can take into account the influence of sound insulation, quiet side of a dwelling, and ambient noise in the neighbourhood. It gives ratings for: • Overall noise climate in residential areas: percentage highly annoyed (%HA); • Night-time noise climate in residential areas: percentage highly sleep disturbed (%HSD); • Hot spots in residential areas: (weighted) number of individuals above limit value L (nL); • Non-Quiet area: percentage area with Lden > 50 dB(A) (AREA50). The indicators can be calculated for a city or parts of it (neighbourhoods), for different types of sources (aircraft, road traffic, railways) separately or for the combined noise from these sources, and for the present situation as well as future situations based on scenarios
