Abstract
The noise characteristics of civil and military aircraft operations differ significantly. For example, the difference in flyover noise from a fighter aircraft and jet plane is easily heard. Civil traffic also tends to be spread out relatively evenly over a day, whereas military training operations can often be characterized by short periods of high activity followed by long periods of comparative silence. Such clearly noticeable differences are disregarded in commonly used noise dose indicators, but may be expected to significantly affect noise annoyance levels within a community. Therefore, an attitudinal survey was conducted by means of telephone interviews in the vicinity of the airports of the Norwegian cities Trondheim and Bodø. While those living near Trondheim's airport are predominantly exposed to noise from civil air traffic, Bodø has a runway that is shared by the city's civil airport and a military airbase. The focus of the study was not on demographic factors, which is typical for an attitudinal study, but instead on acoustical and operational aspects. This study is part of an ongoing research project with the aim of explaining why observed dose-response relationships differ widely from one community to the next.
