A Clinical Test for Sound Localization and Its Applications

Abstract
Literature concerned with the physical, psychological and physiological factors governing sound localization is reviewed. Localization of sound in a horizontal plane by normal individuals was investigated. A Ferre-Rand perimeter to determine the angular deflection and a Maico H 1 audiometer to regulate the sound stimulus were employed. Five cases of temporal lobe lesions examined revealed an impairment in sound localization in the contra-lateral auditory field. The possibilities of this test as a clinical tool and the role of the temporal cortex in the function of sound localization are discussed.
