Abstract : While numerous studies have examined auditory localization processes for relatively distant sound sources very few were interested in sources within 1m of a listener’s head. This study examines the precision of hand reaching movement towards an auditory object. An experimental platform semicircle, radius 1m was constructed with 35 small loudspeakers placed under an acoustically transparent grid. This setup was also established in a virtual auditory environment using binaural synthesis. Blindfolded subjects were seated within the platform at table height. Stimulus positions consists of seven different azimuth angles -30, 0, 30, 60, 90, 120 and 150 degrees with five distances conditions 35, 48 61, 74 and 87 cm. Test protocol consisted of a brief audio stimulus followed by the subject placing their index finger at the location of the sound object. The current experiment explores the effect of the used hand on the reaching error and comparing the performance of real sound localization with virtual sound localization.
