Document Summary
Chapter 12: sound localization and the auditory scene. When you perceive objects located at different positions based on their sounds, you are experiencing auditory space. Auditory space extends around your head in all directions, existing wherever there is a sound. These feats of locating objects in space based on their sound are examples of auditory localization. To determine the location, the auditory system carries out a calculation that makes use of location cues created by the way sound interacts with the listener"s head and ears. Cues for location signals reaching the ears: The two binaural cues interaural time difference and interaural intensity difference are based on a comparison of the sound signals reaching left and right ears. Interaural time difference: difference between the times that the sound reaches the left and right ears. Interaural level difference: is based on the difference in the sound pressure level of the sound reaching the two ears.
