Design and Verification of HeadZap, a Semi-automated HRIR Measurement System

This paper describes the design, development and acoustic verification of HEADZAP, a semi-automated system for measuring head-related impulse responses (HRIR) designed by AuSIM Inc. and modified by the NASA Ames Research Center Spatial Auditory Display Laboratory. HEADZAP utilizes an array of twelve loudspeakers in order to measure 432 HRIRs at 10° intervals in both azimuth and elevation, in a non-anechoic environment. Application to real-time rendering using SLAB software an audio-visual localization experiment is discussed.
