Study on the Delimitation of Noise-affected Areas Utilizing Local Governments’ Methods for Designating Residential and Settlement Districts

Residential areas affected by noise from civilian aircraft, military airfields, and shooting ranges are designated as compensation (damage) areas based on noise levels. However, residents living just outside these designated boundaries often file complaints, arguing that the noise they experience is comparable and requesting inclusion in the compensation areas. The criteria set by the Ministry of Land, Infrastructure and Transport for expanding these boundaries are inadequate for addressing the specific conditions of different regions. To better reflect regional realities, it is recommended to adopt the residential area and settlement zone designation methods used by local governments when establishing criteria for expanding compensation (damage) areas near civilian airports, military airfields, and shooting ranges.
