Abstract

The form of head, torso and especially the form of the pinna play an important role for localizing sound sources. Reflections and deflections especially at the pinna induce filters, the so called head related transfer functions (HRTFs) which are dependent on frequency and location of the sound source. To numerically simulate these functions a 3D-boundary element model of the head was created. As we want to calculate HRTFs up to frequencies of 12000-13000Hz a fine grid is necessary, therefore a huge amount of calculations would be necessary. To avoid this high computational costs the BEM model was coupled with an appropriate fast multipole algorithm.
