Abstract

In this study, the ability of the auditory system to locate the direction of sound sources is evaluated in listeners with normal hearing (NH) and hearing loss (HL). The system, simulated via headphones in a binaural virtual environment, uses a software audiometer based on listener-individual head related transfer functions (HRTFs) and performs signal processing to synthesize 3D audio. The acoustic target was pink noise filtered with the listener specific HRTF to generate the corresponding angle. All NH listeners performed quite well the tested lateral angles ranged from -90º to -150º and from 90º to 150º with a spacing of 30º. However, degradation in localization abilities was observed in the HL results. The audiometric tests proposed complement the information provided by a conventional audiometric test, making them very helpful in the early detection and diagnosis of certain hearing disorders.
