Few socioacoustic studies have examined the effect of noise on outdoor recreationists. The areas studied have been mountain and wilderness areas that people typically travel for a distance to visit. In this article we examine the reactions to aircraft noise in local recreational areas experiencing either decreased (1930 survey respondents), or increased noise exposure (1001 survey respondents). Field studies were conducted before and after the relocation the main airport of Norway in 1998 in one area near each airport. The relationship between individual noise exposure (LAeq for the aircraft events, percentage of time aircraft were audible, and LAsel) for the aircraft events. The analyses included the "situation" in which data were collected (before or after the relocation), and variables describing the recreational context. A strong effect of the "situation" was found in both cases, but the size of the effect was influenced by the choice of exposure variable in one of the study areas. Other context variables were also influencing annoyance. The effect of the situation (before/after a change in exposure) on the dose-response relationship may be influenced by the initial noise levels, the amount of change, and the time elapsed since the change at the time of the second survey. Further research should investigate the significance of these variables.
