Pinnae and Head Movement: The Key to Pre-eminent Auditory Localization Patrice A. Searson Australian Catholic University: Strathfield Word Count: Tutor: Jaymee-Lee Owen Tutorial: Thursday, 4pm Abstract The aim of this current study was to examine people’s ability to locate sound with the use of head movements and the pinnae. 202 participant’s ranging from 18-25 years of age were seated in a chair and where tested on their sound localization in four different conditions; having normal pinnae and no head movement, distorted pinnae and no head movements, normal pinnae and permitted head movement, distorted pinnae and no head moment. Results show that both the pinnae and head movements when used together provide maximum effect to auditory localization. Pinnae and Head Movement: The Key to Pre-eminent Auditory Localization Auditory localisation is a crucial component involved in people’s everyday hearing. It is the ability to situate a source of sound in space; this refers to a person trying to detect the location of a potential sound in direction and distance. Auditory localization relies on the use of binaural cues, monaural cues (Licklider, 1951), the pinnae (Fisher Freedman, 1968) and head movements (Clifton, Perris, Bullinger, 1991). The first components binaural and monaural cues are both extremely important as they help people locate the direction of a sound source from the head. Monaural cues involve the use of only one ear to locate a
