A Combined Laboratory and Field Study of Traffic Noise

Introduction» e 13 !simulated livingroom listening facility has been designed to investigate subjective response to combinations of enviromental noise sources (1).Previous dose-response type research has tended to concentrate on one source only, eliminating or balancing out noise from other sources.It is useful however, to have some information on the differences in response to different noise sources and to changes in noise environment (2).A social survey and measurement programme becomes unwieldy if it is stretched to accomodate several sources at several different levels, quite apart from the difficulty in finding large enough groups of residents with homogeneous noise exposure environments.
