This paper reviews the propagation of sound in the atmosphere to study the impact of aircraft noise, especially looking at the impact from large scale low altitude Unmanned Aircraft (UA) operations for Urban Air Mobility (UAM) in near future. Considering all potential attenuation sources and accounting for uncertainty in aircraft noise emission measurements, major noise sources in an electric Vertical Take-Off and Landing (eVTOL) aircraft are identified and experimentally characterised. Analysing the noise signature for both manned and unmanned aircraft will aid in identifying the models and tools essential for accurately predicting the aeroacoustic performance in varying atmospheric conditions. These surrogate acoustic models can be shown to be sufficient to predict the sound propagation in atmosphere without relying on elaborate computational models or the need to look up aircraft noise databases. The results derived from the analysis can potentially drive the design, test, and operation of noise certification standards for UAM and even improvement of current standards pertaining to noise for conventional aircraft operations.
