Neural coding of interaural time difference
[Proceedings 1992] IJCNN International Joint Conference on Neural Networks, 2003The authors present several ideas relevant to the neural coding of interaural time difference for binaural sound localization. The nonhomogeneous Poisson point process is used to model neural activity in the auditory nerve. A simple paradigm is proposed for relating acoustic stimuli to the intensity function of the Poisson process.

Measurements of Interaural Time- and Intensity-Differences
The Journal of the Acoustical Society of America, 1955Measurements of interaural time-differences and of interaural intensity-differences have been made, employing five subjects and a variety of azimuth positions for the sound source. The time measurements were made using clicks from a movable loudspeaker.

Temporal quantization deteriorates the discrimination of interaural time differences
The Journal of the Acoustical Society of America, 2020Cochlear implants (CIs) often replace acoustic temporal fine structure by a fixed-rate pulse train. If the pulse timing is arbitrary (that is, not based on the phase information of the acoustic signal), temporal information is quantized by the pulse period. This temporal quantization is probably imperceptible with current clinical devices.

Interaural time and amplitude differences together
The Journal of the Acoustical Society of America, 1981Interaural time jnds were measured for a 500-Hz and 1000-Hz tone-burst signal using a 2IFC adaptive procedure. The time delay was presented to one ear in one interval. In addition, an interaural amplitude difference was presented simultaneously. Thus, perceptual movement was created by both an interaural time difference and an interaural amplitude ...

Aging and discrimination of interaural time differences
The Journal of the Acoustical Society of America, 1991Discrimination of interaural time differences (ITDs) was compared between ten younger adults (18–24 years) and ten older adults (66–80 years, with normal or near-normal hearing). Both the mean thresholds and standard deviations for older adults were elevated approximately fourfold compared to the younger subjects.

The problem of different interaural time differences at different frequencies
The Journal of the Acoustical Society of America, 1981Recent research reveals that the interaural time difference produced by a sound source located off the median plane of the body is not frequency independent. The problem this poses for the auditory nervous system is discussed.

Interaction in the perceptual processing of interaural time and level differences
Hearing Research, 2006Phillips and Hall [Psychophysical evidence for adaptation of central auditory processors for interaural differences in time and level, Hear. Res., 202 (2005) 188-199.] recently described the frequency-specific, selective adaptation of perceptual channels for interaural differences in level (ILD) and time (ITD).

Effects of the frequency of interaural time difference in the human brain
NeuroReport, 2006The two cues to the horizontal location sound sources are interaural time differences and interaural level differences. For low-frequency tones, interaural time differences provide effective and unambiguous information. For higher frequency sounds, however, interaural time differences provide ambiguous cues. In order to evaluate the effect of frequency

Interaural Intensity and Time Differences in Anechoic and Reverberant Rooms
Journal of Speech and Hearing Research, 1967The purpose of this investigation was to describe the physical characteristics of an artificial head and to determine the interaural time and intensity changes which occurred at selected azimuths. Measurements were conducted in a reflection free environment and in controlled reverberation conditions.

Cochlear microphonic measurements of interaural time differences in the chick
Hearing Research, 1994The major cues for the sound localization are the interaural differences in the timing and intensity of acoustic information. This poses a difficult coding problem for animals with relatively small heads, such as birds, because interaural time differences (ITDs) would have a small range and magnitude and interaural intensity differences (IIDs) would be
