Adjustment of interaural-time-difference analysis to sound level [PDF]

, 2010
To localize low-frequency sound sources in azimuth, the binaural system compares the timing of sound waves at the two ears with microsecond precision. A similarly high precision is also seen in the binaural processing of the envelopes of high-frequency ...

Anatomical limits on interaural time differences: An ecological perspective [PDF]

Frontiers in Neuroscience, 2014
Human listeners, and other animals too, use interaural time differences (ITD)to localize sounds. If the sounds are pure tones, a simple frequency factorrelates the ITD to the interaural phase difference (IPD), for which there areknown iso-IPD boundaries,

Computation of interaural time difference in the owl's coincidence detector neurons. [PDF]

J Neurosci, 2011
Both the mammalian and avian auditory systems localize sound sources by computing the interaural time difference (ITD) with submillisecond accuracy. The neural circuits for this computation in birds consist of axonal delay lines and coincidence detector ...

Change in the coding of interaural time difference along the tonotopic axis of the chicken nucleus laminaris [PDF]

Frontiers in Neural Circuits, 2015
Interaural time differences (ITDs) are an important cue for the localization of sounds in azimuthal space. Both birds and mammals have specialized, tonotopically-organized nuclei in the brain stem for the processing of ITD: medial superior olive (MSO) in

A Bayesian computational basis for auditory selective attention using head rotation and the interaural time-difference cue. [PDF]

PLoS ONE, 2017
The process of resolving mixtures of several sounds into their separate individual streams is known as auditory scene analysis and it remains a challenging task for computational systems.

Fiber Track Length Gradients in the Avian Sound Localization Circuit Require Conduction Velocity Gradients to Maintain Isochronicity. [PDF]

J Comp Neurol
The gross anatomy of the sound localization circuit in the chicken brainstem was quantified with 3D reconstructions from serial sections and measurements of the interconnecting pathways. A rostral‐to‐caudal length gradient was measured in both the crossed dorsal cochlear track and the ipsilateral loop.

The Effect of Modulation Enhancement Scheme on Speech Recognition in Spatial Noise Among Young Adults with Normal Hearing [PDF]

Audiology Research
Background/Objectives: Speech understanding in noise relies on both temporal fine structure (TFS) and temporal envelope (ENV) cues. While TFS primarily conveys interaural time differences (ITDs) at low frequencies, ENV cues can also support ITD ...

Adaptation in sound localization processing induced by interaural time difference in amplitude envelope at high frequencies. [PDF]

PLoS ONE, 2012
BACKGROUND: When a second sound follows a long first sound, its location appears to be perceived away from the first one (the localization/lateralization aftereffect).

Comparison of Interaural Electrode Pairing Methods for Bilateral Cochlear Implants

Trends in Hearing, 2015
In patients with bilateral cochlear implants (CIs), pairing matched interaural electrodes and stimulating them with the same frequency band is expected to facilitate binaural functions such as binaural fusion, localization, and spatial release from ...

A functional circuit model of interaural time difference processing.

J Neurophysiol, 2014
Inputs from the two sides of the brain interact to create maps of interaural time difference (ITD) in the nucleus laminaris of birds. How inputs from each side are matched with high temporal precision in ITD-sensitive circuits is unknown, given the differences in input path lengths from each side.
