Sound Source Identification for unattended aircraft noise monitoring
Recently, the commercial aircrafts are designed with low noise and high performance. And the aircraft noise level is decreased around the airport by each aircraft. So the noise monitoring system has to measure aircraft noise with low noise level and high frequency around airport that
amount of aircraft operation was increased. Under the condition that the different between the aircraft and other sounds is low, sound source identification of sound event is difficult. We tried to use several information sound level fluctuation, arrival direction, transponder from aircraft,
and others complexly.
