Abstract

The purpose of this study was to examine the perceived location of broadband signals created via binaural recording and then replicated in a virtual listening space. Listeners were asked to localize an auditory target positioned in one of four horizontal quadrants in three vertical planes. A binaural recording was created in both anechoic and echoic environments and subjective tests were conducted. Tests were repeated, with a virtual reality headset to virtually replicate the testing space. Results showed the effectiveness of binaural recording in recreating the perceived source locations in “3-D” space around a specified listening position in different conditions. Statistical analyses revealed accuracy in listener localization response declined when transitioning from free-field to binaural recordings in both anechoic and echoic conditions. When transitioned to a virtual listening space, listeners displayed similar inaccuracy when compared to free-field testing, but neither greater nor lesser accuracy when compared to binaural recording results.
