Abstract: Noise generation due to civil use of unmanned aerial vehicles (UAV) has been identified as an important issue, since they can fly over densely populated areas and the number of potential applications of UAV will increase. This research will help in the small unmanned aerial vehicles (sUAV) noise prediction for commercial and community use of rotorcraft sUAV for take-off and landing operations in vicinity of vertiport. The objective of this study is the development of the simplest noise model of sUAV operations based on acoustic characteristics of its operational modes. Acoustic noticeability is introduced in order to limit the influence of distant sUAV to noise metrics. The model presented in this paper serves as a research platform for assessment and understanding the extent of population exposure to sUAV operation noise in low-altitude urban airspace. Traffic distribution of sUAV flights is proposed based on entropy approach.

Keywords: noise prediction; rotorcraft; small unmanned aerial vehicles; sUAV; annoyance; acoustic noticeability; unmanned traffic management; unmanned aerial vehicles; UAV.
