Abstract

This paper describes and evaluates a measurement setup for individual Head-Related Transfer Functions (HRTFs) in high spatial resolution in a short time period. The setup is constructed to have as little impact on the measurement as possible. It consists of a circular arc segment of approximately 160 degrees on which a large number of broadband loudspeakers are placed forming one continuous surface. By rotating the subject or the arc horizontally, HRTFs are acquired along a spherical surface. To evaluate the influence of the measurement setup a solid sphere and an artificial head are measured and are compared with both the presented system, simulation data using Boundary Element Method, and a traditional, well evaluated HRTF measurement system with only one loudspeaker.
