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 ...

The Journal of the Acoustical Society of America, 1959
The just noticeable differences for changes of interaural time differences between two bursts of noise were investigated as a function of the interaural time difference of the first (reference) burst. Four normal hearing subjects listened through earphones to time differences between ears which were varied by electrical means.

Individual Differences in Sensitivity to Interaural Differences in Time and Level
Perceptual and Motor Skills, 1973Previous research had indicated the existence of two groups—people more sensitive to interaural time differences than to interaural level (intensity) differences and people more sensitive to level differences than to time differences. A population of undergraduates was surveyed in an attempt to estimate the relative proportions of people in the two ...

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.

Detection of sinusoidally modulated interaural time differences
The Journal of the Acoustical Society of America, 1976These experiments were designed to determine the capability of the binaural system to detect sinusoidally modulated interaural time differences. In the first experiments observers were required to discriminate sinusoidally frequency-modulated (FM) tones whose modulation frequencies were interaurally in phase (diotic) from the same FM tones with the ...

Binaural Vector Model: Relative Interaural Time Differences
The Journal of the Acoustical Society of America, 1966Further computations on the binaural vector model have been carried out [H. Levitt and E. A. Lundry, J. Acoust. Soc. Am. 39, 1232(A) (1966), and references cited therein]. The cumulative probability distribution of the phase angle between the left- and right-ear resultant vectors has been computed for the case where either the noise or the signal has ...
