Abstract

This study examined the sound localization of a broadband pink noise burst at various azimuth and elevation angles in a critical listening room. A total of 33 source positions were tested, ranging from 0° to 180° azimuth and -30° to 90° elevation angles with 30° intervals. Results indicated that sound source elevation was localized inaccurately with a large data spread; however, it was improved on the off-center planes. It was observed that elevation localization accuracy was worse on the back compared to the front. Back to front confusion was observed for the sources raised to 60° elevation angle. Proposed listening response method showed consistent localization result and is therefore considered to be useful for future studies in 3D sound localization.
