Auditory Localization Essay -- Hearing Sound Perception Essays

Auditory muddleAuditory placement is the ability to recognize the location from which a choke is emanating (Goldstine, 2002). There are many practical reasons for studying auditory localization. For example, previous research states that visual cues are necessary in locating a particular sound (Culling, 2000). However, blind people do not pose the luxury of sight to help them station a sound. Therefore, the ability to locate sound based only on auditory ability is important. It is likewise important to study different auditory processes. For example, when studying a elan for a blind person to maneuver through an environment, it is helpful to whap that people can most accurately locate sounds that happen powerful away in front of them sounds that are far off, to the side, or behind the transfer are the least likely to be properly located (Goldstein, 2002). 3 coordinate systems are utilized when attempting to locate a specific sound. The azimuth coordinate determines if a s ound is located to the left or the right of a listener. The elevation coordinate differentiates between sounds that are up or down relative to the listener. Finally, the distance coordinate determines how far away a sound is from the receiver (Goldstine, 2002). Different aspects of the coordinate systems are also requirement to sound localization. For example, when identifying the azimuth in a sound, three acoustic cues are used ghostlike cues, interaural time differences (ITD), and interaural level differences (ILD) (Lorenzi, Gatehouse, & Lever, 1999). When dealing with sound localizaton, spectral cues are teh distribution of frequencies reaching teh ear.
