A method for plausible road tyre noise auralization

Interest in research relating to the impact and abatement of road traffic noise has increased since the Environmental Noise Directive was introduced. The World Health Organisation has recognized road traffic noise as a serious problem for public health, and annoyance with some aspect of our daily soundscape is well recognized as a common complaint. Auralization tools can allow designers, planners and relevant stakeholders to listen and converse on human response to a planned development or mitigation strategy. An ideally detailed road traffic noise auralization system would render the acoustic emission of every vehicle on the road network at any desired receptors. This work focuses on the sound emission from the road tyre interaction for the purpose of auralization and extends on previous work for synthesising road tyre noise based on a small dataset of roadside recordings. The proposed method discussed in comparison to a recently published approach and the plausibility of the proposed method is verified.
