The airport is chosen as the measurement airport in this paper to investigate the noise characteristics of piston engine aircraft used for training at Muan airport. Five measurement points near the runway are chosen. The maximum noise values of piston engine aircraft (C172) and SR20 take-off processes are measured. The results show that the average maximum noise values of the five measuring points range from 66.5 dB(A) to 76.7 dB(A), with point C having the greatest noise influence. During take-off, the maximum noise of an SR20 aircraft occurs near 500Hz of low frequency.
