Localization by interaural time difference (ITD): Effects of interaural frequency mismatch
The Journal of the Acoustical Society of America, 1999A commonly accepted physiological model for lateralization of low-frequency sounds by interaural time delay (ITD) stipulates that binaural comparison neurons receive input from frequency-matched channels from each ear. Here, the effects of hypothetical interaural frequency mismatches on this model are reported. For this study, the cat’s auditory system

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.

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 ...

Differential lateralization interference for interaural time and interaural level differences
The Journal of the Acoustical Society of America, 1991Lateralization thresholds were obtained in a 21FC task using 200-ms noise bands presented with either an interaural time or level difference. The elevation in lateralization threshold (interference) caused by a simultaneously presented noise band was measured.

Detecting interaural time differences and remodeling their representation
Trends in Neurosciences, 2014Interaural time differences (ITDs) represent an important cue in sound localization and auditory scene analysis. To assess this cue the auditory system internally delays binaural inputs to compensate for the outer delay, before neurons in the brainstem detect the coincident arrival of the inputs from the two ears.

Changes in interaural time sensitivity with interaural level differences in the inferior colliculus
Hearing Research, 2007We measured interaural time difference (ITD) sensitivity of 72 cells in the inferior colliculus of the anaesthetised guinea pig as a function of frequency and interaural level difference (ILD). For many units there was a "null" frequency, where varying the ILD made no difference to the position of the peak of the ITD sensitivity.

Threshold interaural time differences under optimal conditions
The Journal of the Acoustical Society of America, 2018Klumpp and Eady (1956, J Acoust Soc Am 28, p.859-860) reported preliminary data on human sensitivity to interaural time differences (ITD) with various stimuli. At 10 μs ITD the best discrimination of 79% correct was reported for band-pass filtered (150-1700 Hz) noise.

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.

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.

Discriminability of Interaural Time Difference
The Journal of the Acoustical Society of America, 1953Using earphone presentation and electrical lag lines which allow precise control of time delays, measurements were made of interaural time difference thresholds for pure tones and noise bands. The time difference threshold is here defined as the minimal change in interaural time difference which elicits a perceptible shift in the location of the sound ...
