Abstract
A social survey investigation was made in 20 areas around eight shooting ranges for heavy weapons to test the applicability of a non-linear dose–response relationship with a breakpoint for number of events. The noise exposure was expressed using the integrated value L CDN as well as the number of events at different levels and the noise levels from the noisiest events. The extent of annoyance was determined among 1483 randomly selected persons using a postal questionnaire. Heavy weapon shooting noise (HWSN) caused interference with rest, recreation and sleep and the effects were experienced as most annoying in the evening and at night. When the exposure was expressed as the number of shots with a level higher than 90 L CS and the highest L CX value at each side as independent variables, a non linear dose–response relationship with a breakpoint for the number of events at a very low number was found. The shape of the dose–-response curve was similar to the one earlier found for other types of environmental noises. It is suggested that guidelines for HWSN be based on this type of dose–response relationship.
