In the framework of the EPSRC-UK DroneNoise project, a multi-channel methodology for small Unmanned Aircraft Systems (sUAS) noise measurement was applied under controlled conditions. The measurement campaign was carried out in August 2022 in Edzell, a village in Scot-land. This paper presents preliminary results on the application of this on-field measurement protocol for a series of sUAS during hovering. Noise signals were recorded from two quadcopters and one hexacopter in stationary flight using a linear ground microphone array. The data were then analysed in both time and frequency domains. In addition , back-propagation techniques were applied for the calculation of noise directivity. Comparisons of the acoustic footprint of the tested sUAS were carried out using both acoustic metrics and Sound Quality Metrics (SQMs). The analysis procedure presented in this paper can also report SQMs at different receivers to aid the psychoacoustic assessment of sUAS noise.
