Abstract
Unmanned Aerial Vehicles (UAVs) and Urban Air Mobility (UAM) vehicles mark a major advancement in aviation technology, with the potential to reshape the future of aviation, particularly in the field of transportation and logistics in urban and rural environments.
Undoubtedly, the noise generated by their unique propeller-driven propulsion systems poses a significant public health concern. Operating at low altitudes throughout their missions and producing an acoustic signature characterized by strong tonal noise and prominent high-frequency components, these vehicles are expected to have a greater impact on communities than traditional aircraft....
