The Contribution of Individual HRIRs on Externalization
* Presenting author
Listeners perceive the sounds of the real world to be externalized. For sound sources in closed environments this is largely due to interaural cues provided by the reverberation of the room described by the room impulse response (RIRs) and the filtering by head, torso, and pinna expressed as head-related impulse responses (HRIRs). The latter vary with listeners and it is known that individual HRIRs improve the externalization. To provide more insights into the relative contribution of RIRs and HRIRs on the externalization we performed a listening experiment. Listeners were asked to rate the externalization of speech convolved with different RIRs with individual and generic HRIRs. The results of the experiment suggest that the importance of individual HRIR diminishes with increasing reverberation time.
