광주공항 주변의 소음도 분포 조사 연구 = A Study on Assessment of Aircraft Noise in Kwang-ju Airport

다국어 초록 (Multilingual Abstract)

This study investigates the measurement and analysis of aircraft noise around Kwang-ju airport the results were as follows:
The Flights per day at the Kwangju Airport are about 20 for civilian passenger airliner and about 40 for military plane but since military planes have irregular flight schedules and frequency, their operation is flexible according to military operations and other conditions.
The noise of airplane around the populated area of the Airport indicates a serious situation of around 85 WECPNL in Woosan-dong, Songdae-dong and Shinchon-dong. Noise levels are within the expected noise pollution limits in dukheung-dong, Chipyung-dong and Bonduk-dong.
Airplane noise in the density populated areas is lower than 80 WECPNL, the expected the noise pollution levels, and that for military planes is higher than that of civilian passenger airliners by 10 WECPNL and that of Woosan district is the highest of the three districts.
In general, the frequency spectrum of military planes is around the 1000~2000Hz band, compared to that of civilian passenger airliners and noise level is higher by over 20dB. This is why the sound of the military plane is much louder and sharper, and it occurs in the frequency band causing sensitive response upon being heard.
