Abstract

We realize a perceptual comparison of spatial sound localization using a synthetic pink noise and four recognizable sound sources: male and female speech, a closing door, and a sea-sound recording. Spatialization is created via binaural recording (Soundman OKM binaural microphones) or HRTF post-processing using filters available in Logic Pro, Protools, and Matlab. Eleven participants had to locate the source position of 72 stimuli combining different locations in azimuth. Results show that location recognition is generally low (36%). Although Soundman recordings show better results, no significant difference in localization accuracy is found between HRTF filtering systems and the binaural microphone recordings. We conclude that binaural 3D sound can easily be implemented with available commercial software, with no clear difference between systems.
