Developing a noise and soundscape conceptual framework for fair and equitable distribution of aircraft (2024)
Presentation / Conference Contribution

Fair and Equitable Distribution (FED) of aircraft, was introduced in 2015 as an aspirational objective by communities affected by aircraft noise from Gatwick Airport, the third-busiest airport by total passenger traffic in the UK. This paper present... Read More about Developing a noise and soundscape conceptual framework for fair and equitable distribution of aircraft.

Noise from Unconventional Aircraft: A Review of Current Measurement Techniques, Psychoacoustics, Metrics and Regulation (2023)
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.

Auditory Alerts for E-scooters: Relationship Between Pedestrian Auditory Detection Rates and Alert Sound Level (2023)
Journal Article

Electric micromobility has the potential to transform the urban transportation system by offering increased personal mobility, whilst reducing congestion and air pollution. Standing electric scooters (e-scooters) are considered as the most popular mo...

sUAS Noise characterization during hovering operations (2023)
Presentation / Conference Contribution

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,... Read More about sUAS Noise characterization during hovering operations.

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.

Acoustic and Psychoacoustic Characterisation of Small-Scale Contra-Rotating Propellers (2023)
Journal Article

This paper reports an experimental investigation of noise radiation and psychoacoustic evaluation of contra-rotating propellers with different blade counts over multiple emission angles and thrust settings. A series of aeroacoustic and psychoacoustic... Read More about Acoustic and Psychoacoustic Characterisation of Small-Scale Contra-Rotating Propellers.

On-field noise measurements and acoustic characterisation of multi-rotor small unmanned aerial systems (2023)
Journal Article
