Head-Tracked Auralization of Acoustical Simulation

A desirable feature of modern acoustical simulation programs is the easy, fast and reliable auralization of prediction results. To be considered as a serious tool, the auralization results should be equivalent to human perception in reality. In this paper we consider a new auralization technique, based on a head-tracked headphone system with high spatial resolution and real-time convolution. We discuss the measurement of directional head-related transfer functions, the calculation of directional binaural impulse responses and the realisation as a real-time convolution software. A listening test was performed, comparing reality, measurement and prediction results for an example room.
