A study on the correlation between aircraft noise units and weather conditions using automatic noise measurement data

Currently, an increase in the number of flights due to the development of the aviation industry, the airport noise problem has emerged as a social problem. Accordingly, major airports in Korea are implementing the Noise Abatement Operational Procedures recommended by the International Civil Aviation Organization. The major airports have established and operated the take-off noise limit standards for aircraft operating at airports by installing an automatic noise measurement around airports. The take-off noise standards of airports should be established in consideration of both the operating conditions and environmental factors of each airport. Furthermore, which can be a sensitive topic between the residents of the airport and the airlines operating at the airport, so it will be presented more scientifically and reasonably. This study statistically analyses the correlation between the noise measurement units Lmax and EPNL, and analyse the correlation between noise and temperature, humidity, wind direction, and wind speed by using 5 years of environmental data and noise data collected from 2015 through the automatic noise measurements around A airport.
