Comparison of Road Tyre Noise Auralisation Methods

Since the Environmental Noise Directive was introduced there has been an increase in the number of publications considering the impact and abatement of road traffic noise. The World Health Organisation has recognised road traffic noise as a serious problem for public health and annoyance with some aspect of our soundscape is well recognised as the most common complaint. Auralisation tools can allow designers, planners and stake holders to listen to the effect that a planned development and any associated noise mitigation can have on people. An auralisation generally consists of three key components sound sources, acoustic transmission paths and a calibrated soundscape listening system. The overarching goal of this work is to achieve a detailed road traffic noise auralisation system where the acoustic emmission of every vehicle on the road network is accounted for at the desired listening position. This work extends on a previously presented method for synthesising road tyre noise based on a small dataset of road side recordings and validates the plausibility of this method in comparision to a recently published approach.
