Drones, also known as Unmanned Aerial Vehicles (UAVs), have rapidly integrated into various industries, from delivery services and agriculture to surveillance and disaster response. However, their increasing use has brought concerns about noise pollution, particularly in urban and residential areas. Unlike traditional aircraft, drones produce high-frequency, tonal noise, which can be more annoying to people. This study explores different methods for assessing drone noise, understanding its impact on communities, and identifying ways to mitigate it. This research also analyzed how drone noise propagates outdoors, how much enters buildings, and how it affects people indoors—especially during sleep. Factors like drone size, the number of rotors, flight maneuvers, and weather conditions significantly influence noise levels.
