Multimodal Perceptual Training Improves Spatial Auditory Performance in Blind and Sighted Listeners

Authors: Oana Bălan, Alin Moldoveanu, Florica Moldoveanu in: Archives of Acoustics (Accepted for publication) Abstract: The use of individualized Head Related Transfer Functions (HRTF) is a fundamental prerequisite for obtaining an accurate rendering of 3D spatialized sounds in virtual auditory environments. The HRTFs are transfer functions that define the acoustical basis of auditory perception of a sound source… Continue Reading Multimodal Perceptual Training Improves Spatial Auditory Performance in Blind and Sighted Listeners
