Characteristics of aircraft flypast noise around Singapore Changi international airport

There is an increased concern about aircraft flypast noise, especially for residents living near an airport. Airlines typically fly at lower heights near the airports for taking off and landing. In this study, we measured the aircraft flypast noise near the Singapore Changi Airport, and the measurement locations were about 1.5 km away from the tip of the nearest runway. For the incoming flights, the average continuous sound pressure levels for the 12 aircraft recorded were 69.6 dB(A) and 77.8 dB(C), with an average difference of 8.3 dB between dB(A) and dB(C) scales. The plane flypast noise for the taking-off aircraft was significantly higher than that of incoming aircraft. The average continuous sound pressure levels for the 17 aircraft were equal to 75 dB(A) and 84 dB(C). The present study has shown a significant difference in the noise level between taking off and landing and between A-weighting and C-weighting measurements. (C) 2021 Elsevier Ltd.
