Study of organized data processing method complement each other of aircraft noise and flight path in aircraft noise monitoring

摘要

The performance of the aircraft improved, the way of operation was devised, and the noise situation around the airport was improved as a result. However, the introduction of a new operation method such as area navigation causes low-level and . high-frequency aircraft noise problems, monitoring low-level aircraft noise under environmental noise becomes important, noise detection and sound source identification has become an issue. On the other hand, we observe the flight path and disclose it as information or use it for noise prediction. Trying to associate the track data with the result of the noise monitoring is quite difficult because the difference between the aircraft and the background noise is small and the noise event cannot be observed even if the aircraft fly near the monitoring point. On the other hand, aircraft not equipped with ADS-B are still operating in Japan. The flight path of such aircraft, small passenger compact aircraft and military aircraft cannot be acquired unless it is a pseudo radar type observation device. Therefore, we examined a method to comprehensively complement the results of noise monitoring and observation of multiple flight paths and to comprehensively grasp the operational status of aircraft around the airport.
