국내 항공기 소음 성가심 조사 설계 시 고려해야 할 변수에 관한 연구

For the purpose of finding if aircraft noise annoyance response is affected to variables when noise survey is performed, the questionnaire survey is conducted around the Gimpo International Airport in Seoul, Republic of Korea. This residential area is exposed to the aircraft noise and road traffic noise, simultaneously. Research areas are classified according to three different aircraft noise exposure levels expressed in WECPNL, under 75, between 75 and 80, and above 80 WECPNL, on aircraft noise map. The 7-step numerical magnitude with verbal category scales is used to measure the annoyance level. This surrey suggests that aircraft noise annoyance is not affected to an important extent by other noise sources (road traffic noise, community noise) and demographic variables (sex, age, education, occupation, dwelling type, length of residence). Aircraft noise annoyance would be related to complaint activity which is one of attitudinal variables.
