Boundary Element Simulation of HRTFs and Sound Fields Produced by Virtual Acoustic Imaging Systems

Document Thumbnail

The goal of using the Boundary Element Method (BEM) in this study is two-fold: to replicate a set of measured, individualized HRTFs by a computer simulation, and also to visualize the resultant sound field around the head. This paper presents the results of a preliminary study carried out on a KEMAR dummy-head, the geometry of which was captured with a high accuracy 3-D laser scanner and digitizer. The scanned computer model was converted to a few valid BEM meshes with different polygon resolutions, enabling us to optimize the simulation for different frequency ranges. The results show a good agreement between simulations and measurements of the sound pressure at the blocked ear-canal of the dummy-head up to the maximum frequency investigated-(6 kHz). Also presented are some examples of the resultant sound fields for virtual acoustic imaging systems.
