註釋DESCRIPTORS: (*Public opinion, *Sociology, *Jet engine noise, A IRPL E ENGI E NOISE, Jet plane noise.) To determine preliminary relationships b twe n variations in acoustic situations and disturbance, annoyance, and complaint potentials, personal interviews were held with almost 2500 residents at different air ba es. The detailed acoustic conditions at three bases were measured. From these studies, the instruments and procedures for assessing neighborhood reactions were fully developed, pretested, and validated. The data provided valuable findings and the development of prototype statistical models for estimating neighborhood disturbance, annoyance, and complaint readiness. Community reactions are directly related to the intensity noise levels. A person is more disturbed, annoyed, and ready to complain if he is fearful of crashes and feels the air base is less important to local welfare and is less considerate of neighborhood feelings. Greatly disturbed people are also less satisfied with general living conditions in their areas, are more sensitive to noi e of cars and trucks, and have less experience with flying. Time by itself has been proved no automatic cure of the annoyance problem. People who have lived n ar air ba es longer are even more bot ered by the airplane noise. (Author).
