BRIR Refinement with Bone Conduction Headphones to Improve Spatial Sound Reproduction in Conventional Headphones

摘要

Conventional BRIR (Binaural Room Impulse Response) measurement uses only miniature microphones plugged on the entrance of the ear canal to pick up acoustic sound entering the subject's ears. Though simple, this method does not consider the resonance of the ear canal, among other factors. In this paper, the measured BRIRs are refined by using bond conduction headphones to include these factors. Experimental results show that the refined BRIRs produce better distance localization than without the refinement.
