Summer 2008: Identification of Candidate Acoustic Cues for Sound Localization

By Rishi Kothari

Sound localization is an important ability for all animals for a variety of reasons, including avoiding predation and finding food. The localization of sound in animals, as well as humans, has been investigated extensively with respect to varying azimuth, but substantially less study has been done on the effects of changing the distance or elevation of the sound source. Here, we investigate candidate acoustic cues for the determination of distance and elevation using head-related transfer functions (HRTFs) from the dutch-belted rabbit due to the wealth of information available about its auditory system.
