Abstract

Auralisation of road traffic noise has gained an increased amount of attention in the literature in recent years. Tools are required that can form the basis for the proper evaluation of the subjective aural impact of planned or existing road transport developments in residential areas. This paper presents a new framework for the capture, analysis and synthesis of moving road vehicles within a virtual auditory environment rendered using spatial sound techniques for headphone or loudspeaker based systems. The new framework is presented in the context of the spatial sound rendering of a single car pass-by sourced from a roadside recording. The analysis and synthesis processing is performed in the time-frequency domain and incorporates changes at the listening position based on an approximation of the vehicle’s directional noise radiation pattern. The presented framework is then used to generate single vehicle pass-bys that simulate the original vehicle recording. Blind listening tests indicate that the processing framework can reliably synthesize vehicle pass-by noise in a manner that listeners deem subjectively plausible.
