Noise Level Analysis by Aircraft Type in Service in Korea: Case Study of Gimhae Airport

Countermeasures for the abatement of aircraft noise include relocation of runways, building new runways, implementing measures pertaining to the noise propagation path such as installation of noise barriers and tree belts, and following point measures such as installing soundproof windows in residential areas in the vicinity. However, in order to reduce aircraft noise, which is a point source generated in the air, the former two measures are difficult to adopt from a practical perspective, and therefore, more efficient and practical measures must to be considered. Currently, the most efficient noise control measures are the methods related to controlling the noise source such as the introduction of low-noise aircrafts, regulation of flights, and low-noise flight procedures. In order to assess these noise reduction measures, accurate noise level analysis of the noise source, i.e., the aircraft, is necessary. In this study, we aim to analyze the noise level of each aircraft type, primarily in the Gimhae region so that the results can be used as basic aircraft noise data for reflection and application in the formulation of airport noise policies.
