Acoustic and Psychoacoustic Characterisation of Unmanned Aircraft Systems as a Function of Vehicle Mass and Flight Procedure (2024)
Presentation / Conference Contribution

Previous studies have found the noise emission of Unmanned Aircraft Systems (UAS) highly dependent on the vehicle mass and flight procedure. These changes in noise emission, as well as the position of the UAS relative to the receiver, have led to cha...

Boundary Layer Ingestion Ducted Fan: Aeroacoustic and Psychoacoustic Insights (2024)
Presentation / Conference Contribution

An in-depth experimental study was conducted to investigate the noise characteristics of a ducted fan ingesting an adverse pressure gradient turbulent boundary layer, typical of those encountered in novel airframe-integrated propulsion systems. To ga... Read More about Boundary Layer Ingestion Ducted Fan: Aeroacoustic and Psychoacoustic Insights.

Synthesis and Auralisations of Quadcopter Flyovers for Psychoacoustic Assessment. (2024)
Presentation / Conference Contribution

This paper describes a methodology to generate auralisations of quadcopter flyovers from recordings of hovering operations. The primary focus of this investigation is reproducing changes in the tonal components at the blade passing frequencies and th...

This paper presents the results of a listening experiment designed to assess annoyance and perceived loudness (PL) for several unmanned aircraft system (UAS) operations, with the listener simulated in indoor and outdoor positions. This research inves... Read More about Perception of noise from unmanned aircraft systems: Efficacy of metrics for indoor and outdoor listener positions.

sUAS noise characterisation during hovering operations (2024)
Presentation / Conference Contribution

In the framework of the EPSRC - UK DroneNoise project, a multi-channel methodology for small unmanned aerial systems (sUAS) noise measurement was applied under controlled conditions. The measurement campaign was carried out during August 2022 in Edze... Read More about sUAS noise characterisation during hovering operations.

Investigating the Dose Response of UAS Noise: Designing a Listening Experiment (2024)
Presentation / Conference Contribution

In collaboration with the UK Civil Aviation Authority, the University of Salford is carrying out research to better understand the human perception and dose response of Unmaned Aerial Systems (UAS) noise. A listening experiment has been conducted to... Read More about Investigating the Dose Response of UAS Noise: Designing a Listening Experiment.

Journal Article

Purpose of Review: This review aims to evaluate and discuss the current advances in the measurement and assessment of the noise generated by unconventional aircraft, such as unmanned aircraft systems (UAS) and urban air mobility (UAM) vehicles. Build... Read More about Noise from Unconventional Aircraft: A Review of Current Measurement Techniques, Psychoacoustics, Metrics and Regulation.

On-field measurement for sUAS noise characterization (2023)
Presentation / Conference Contribution

With the imminent introduction of multi-rotor aircraft systems
in airspace and the expectation of their operation
near urban areas, noise emissions from this new type of
noise sources have become an important research topic,
mainly because they h... Read More about On-field measurement for sUAS noise characterization.
