This presentation will overview the current state-of-the-art methods to model and assess aircraft noise, with a particular focus on conventional practices used in regulatory and operational contexts. It will highlight key research gaps in extending these approaches to assess noise from emerging innovative air mobility (IAM) technologies, such as electric vertical take-off and landing (eVTOL) aircraft. These gaps include challenges related to novel vehicle configurations, complex noise signatures, and particular operational conditions with IAM aircraft operating closer to communities. The presentation will also showcase recent work at the University of Salford aimed at advancing modelling tools and assessment methods for IAM noise, including integrated efforts within an innovative framework of perception-driven engineering. Progress in auralisation and psychoacoustic methods for IAM noise will be presented and discussed.
