Noise is defined as ‘unwanted sound’ or ‘undesired sound’. Recently, the aviation industry has been rapidly developing through convergence with cutting-edge technologies such as UAM. Accordingly, it is expected that new aviation industry models will continue to be created in Korea. In addition, it is expected that aircraft noise will be raised as a new social problem. The characteristic of aircraft noise is that it has a wide transmission range. Therefore, the area affected by aircraft noise is extensive, and the damage area varies depending on the flight path and flight environment. Additionally, it tends to occur continuously in certain areas. This study is an extension of the previous studies 󰡔Study on noise measurement and analysis of C172 aircraft at Muan Airport󰡕 and 󰡔Study on noise measurement and analysis of SR20󰡕, and investigated the noise characteristics of various piston engine trainer aircraft operated in Korea. We want to measure and analyze noise.
