Binaural transfer path synthesis

Abstract

In this chapter, the acoustic model of airborne and impact sound transmission and the subsequent auralization technique is generalized to other applications in acoustics and noise control engineering. It was shown that the resulting sound pressure signal at the listener’s ears can be constructed by using binaural filters. Sound transmitting elements are accounted for by their transfer function to achieve the correct level and colouration. Phase aspects can often be neglected in the diffuse field conditions in the listener’s environment. Components of early, primary sound, however, must be modelled with their phase or group delay which enhances the presence and immersion and the correct localization. From these components, sources and transfer paths can be constructed and combined into an efficient auralization model.
