HRTF SIMULATIONS THROUGH ACOUSTIC RAYTRACING

The determination of individual head-related transfer functions (HRTF) for 3D sound rendering remains a challenging task. The measurement of individual HRTFs is not practical, due to the requirements of heavy and expensive equipment as well as an anechoic chamber for the measurement itself. Some techniques have been proposed to individualize general HRTFs, but still many restrictions apply. This work describes an alternative approach for measuring individual HRTFs through acoustic raytracing. We designed a system that is able to load individual 3D meshes and perform an HRIR simulation. Although, we mainly focus on spectral reflections, we also simulate frequency dependent diffraction, absorption and transmission effects.
