Job description

Aircraft noise is a cause of annoyance and severe adverse health effects to millions of people living in the vicinity of airports. In addition, noise emissions remain the biggest inhibitor to aviation growth, since strict noise regulations limit the capacity of airports. The continuous growth of air traffic, only worsens this situation and brings urgency to this matter.

One of the crucial remaining challenges in order to protect the quality of life and living environment around airports is to perform accurate assessment and modelling of the noise annoyance caused by aviation. Conventional sound metrics typically employed for by authorities for noise assessment do not properly consider human perception of sound and, as such, it is highly questionable to use them to assess noise annoyance. In contrast, novel sound quality metrics from the psychoacoustics field are expected to be more suitable for this purpose.

This PhD project will focus on the development of novel perception-based assessment techniques and modelling of aircraft noise annoyance. The PhD researcher will benefit from the extensive in-house expertise in the field. To perform the necessary experiments, the PhD researcher will be able to use the state-of-the-art equipment present at the research group, such as microphone arrays for acoustic measurements and the newly-developed psychoacoustic listening room.

The main objectives of this PhD project are to:

• Determine the main sound characteristics of aircraft noise that influence the perceived annoyance via listening experiments.
• Develop semi-empirical noise annoyance prediction models for current aircraft (turbofan and turboprop), as well as for near-future aviation concepts (unconventional aircraft configurations, drones, urban air mobility vehicles).

Based on experiments in wind tunnels (and potentially full-scale aircraft flyover measurements), assess how innovative aircraft technologies (such as those designed to reduce fuel burn and pollutant emissions) would affect the noise annoyance experienced around airports.

Department
Faculty Aerospace Engineering

The Faculty of Aerospace Engineering at Delft University of Technology is one of the world’s most highly ranked (and most comprehensive) research, education and innovation communities devoted entirely to aerospace engineering. More than 200 science staff, around 250 PhD candidates and over 2,700 BSc and MSc students apply aerospace engineering disciplines to address the global societal challenges that threaten us today, climate change without doubt being the most important. Our focal subjects: sustainable aerospace, big data and artificial intelligence, bio-inspired engineering and smart instruments and systems. Working at the faculty means working together. With partners in other faculties, knowledge institutes, governments and industry, both aerospace and non-aerospace. Working in field labs and innovation hubs on our university campus and beyond.

Additional information

The mission of the department of Control and Operations is to improve the safety and efficiency of operations in aerospace and to reduce their impact on the environment. The department comprises three sections: Control and Simulation, which focuses on the development of advanced automatic control systems (including the role of the human operator), Air Transport Operations, which aims to improve operational performance in terms of capacity, safety, and economy, and Aircraft Noise and Climate Effects, which focuses on reducing aircraft noise, emissions, and the effects of aviation on climate change.

The Aircraft Noise and Climate Effects (ANCE) section focuses on modelling the effects of aviation on the environment with respect to noise and emissions. The section works on detailed aircraft noise source modelling, considering both the engines and airframe, e.g. for the assessment of new aircraft technologies. The section develops models capable of assessing the aviation-induced climate effects by calculating the contribution of individual climate agents such as carbon dioxide and ozone. This enables assessing the effectiveness of mitigation measures such as climate­optimised routing.
