Mechanisms of Sound Localization in Mammals
Physiological Reviews, 2010The ability to determine the location of a sound source is fundamental to hearing. However, auditory space is not represented in any systematic manner on the basilar membrane of the cochlea, the sensory surface of the receptor organ for hearing. Understanding the means by which sensitivity to spatial cues is computed in central neurons can therefore ...

Synaptic depression in the localization of sound
Nature, 2003Short-term synaptic plasticity, which is common in the central nervous system, may contribute to the signal processing functions of both temporal integration and coincidence detection. For temporal integrators, whose output firng rate depends on a running average of recent synaptic inputs, plasticity modulates input synaptic strength and thus may ...

The Journal of the Acoustical Society of America, 1938
The binaural cues for sound localization are effective only in determining the angle between a given direction of sound and the axis of the ears (lateral angle). Since there is localization in the median plane, a second factor should be found which determines the direction of sound in this dimension.

The Journal of the Acoustical Society of America, 1959
When one listens to a transient type signal from two equidistant loudspeakers in free space, he experiences the sensation of a single well-defined source. The apparent position of the source can be altered by adjusting the relative outputs of the two speakers, by delaying the signal from one or by a combination of level and delay adjustments.

The ability to localize the source of a sound is important to the survival of human beings and other animals. Although we regard sound localization as a common, natural ability, it is actually rather complicated. It involves a number of different physical, psychological, and physiological, processes.

Neural Mechanisms for Sound Localization
Annual Review of Physiology, 1984Although the efforts to find a place map of sound direction within the auditory system of mammals has been reinspired by the recent discoveries in owl, progress to date has not been encouraging. Neither the inferior colliculus nor auditory cortex has yielded immediate evidence of such a map, despite ingenious and persistent efforts to find it. Thus, at

Active stereo sound localization
The Journal of the Acoustical Society of America, 2003Estimating the direction of arrival of sound in three-dimensional space is typically performed by generalized time-delay processing on a set of signals from a fixed array of omnidirectional microphones. This requires specialized multichannel A/D hardware, and careful arrangement of the microphones into an array.

Hearing: recognition and localization of sound
2008In this chapter the problem of recognition and localization of a sound source is discussed. The starting point is the solution adopted by the cricket able to identify an auditory stimulus and to reach the sound source. The auditory process has been modelled with a network of neurons with the aim to realize a bio-inspired auditory system for robotic ...

Underwater sound localization in humans
The Journal of the Acoustical Society of America, 1973Theory and some empirical evidence would predict that humans should exhibit little ability to localize sounds underwater; however, other observations seemed to contradict this position. In order to provide relavant data on the issue, a pilot study was conducted; its results suggested that man can localize sounds underwater—at least to some degree ...

The Role of Posture in Sound Localization
Quarterly Journal of Experimental Psychology, 1974Studies of auditory localization revealed that where a subject hears a sound is dependent on both his perceived head position and the auditory cues at his ears. If an error is induced between his true and registered head posture, then errors in his auditory localizations of corresponding size and time course result.
