Study on Evaluation about Aircraft Noise Around Airport

The measurements of aircraft noise around several airports and survey on reactions of people to aircraft noise were taken in 1984 and 1985. Some results about duration of aircraft noise and relations between PNL and Sound level A and D of aircraft noise are found by statistacal analysis of data obtained in the survey and measurements. These results indicate that WECPNL is an effective measure of aircraft noise not only in physical but also in psychological evaluation.
