Sound localization is a listener's ability to identify the location or origin of a detected sound in direction and distance. The sound localization mechanisms of the mammalian auditory system have been extensively studied. The auditory system uses several cues for sound source localization, including time difference and level difference (or ...
Acoustic wayfinding, the practice of using auditory cues and sound markers to navigate indoor and outdoor spaces; Animal echolocation, animals emitting sound and listening to the echo in order to locate objects or navigate; Echo sounding, listening to the echo of sound pulses to measure the distance to the bottom of the sea, a special case of ...
Unlike most sound-localization maps, this map was found to be two-dimensional, with units arranged spatially to represent both the vertical and horizontal location of sound. Knudsen and Konishi discovered that units in this structure respond preferentially to sounds originating in a particular region in space.
3D sound reconstruction is the application of reconstruction techniques to 3D sound localization technology. These methods of reconstructing three- dimensional sound are used to recreate sounds to match natural environments and provide spatial cues of the sound source.
A general way to implement 3d sound localization is to use the HRTF(Head-related transfer function). First, compute HRTFs for the 3D sound localization, by formulating two equations; one represents the signal of a given sound source and the other indicates the signal output from the robot head microphones for the sound transferred from the source.
The central nucleus of the IC is a nearly obligatory relay in the ascending auditory system, and most likely acts to integrate information (specifically regarding sound source localization from the superior olivary complex [13] and dorsal cochlear nucleus) before sending it to the thalamus and cortex.

Ida Zündorf, Hans-Otto Karnath and Jörg Lewald carried out a study in 2010 which investigated the advantages and abilities males have in the localization of auditory information. [27] A sound localization task centered on the cocktail party effect was utilized in their study. The male and female participants had to try to pick out sounds from ...
Lloyd Alexander Jeffress (November 15, 1900 – April 2, 1986) [1] was an acoustical scientist, a professor of experimental psychology at the University of Texas at Austin, [1] and a developer of mine-hunting models for the US Navy during World War II and after, [2] Jeffress was known to psychologists for his pioneering research on auditory masking in psychoacoustics, his stimulus-oriented ...
