Currently, many complaints have been filed by local residents on helicopter noise while the law on noise prevention and damage compensation at military airfields and military ranges has been in effect since November 27, 2020. The airfields operated by state agencies are inevitably used to defend the country, defend the country, and protect the lives of the people, but various efforts are needed to minimize noise complaints. In general, helicopters operating in a specific area exhibit different noise frequencies depending on the number or size of wings for each type, takeoff speed, and takeoff altitude. Therefore, by measuring and analyzing noise in the take-off stage of a number of helicopters operating in a specific area, this study aims to present more effective noise prevention measures by analyzing the compliance of each type of helicopter with variables such as take-off speed, take-off altitude, and rise rate. Therefore, the results of this study will be significant in terms of resolving complaints and reducing compensation expenditures of local residents around the airport.
