Optimal codes for processing interaural time differences.
The Journal of the Acoustical Society of America, 2010It has been argued that a graded code with two populations of neurons tuned at two symmetrical delays is optimal for ITD estimation. However, this theoretical result critically relies on the assumption that the only source of uncertainty is the randomness of spiking, while the source signal is fixed (a pure tone).

Auditory spatial attention using interaural time differences.
Journal of Experimental Psychology: Human Perception and Performance, 2000Previous probe-signal studies of auditory spatial attention have shown faster responses to sounds at an expected versus an unexpected location, making no distinction between the use of interaural time difference (ITD) cues and interaural-level difference cues.

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.

Detectability was measured as a function of signal duration for a dichotic condition in which there was only an interaural difference in level and for one in which there was only an interaural difference in time. For four subjects, performance improved as duration increased, and it did so in essentially the same way for the two dichotic conditions ...

Detection of a low-frequency tonal signal in the presence of various types of masker was studied using a two-alternative temporal forced-choice paradigm. The first experiment employed a tonal masker of the same frequency as the signal (500 Hz). The phase angle between signal and masker was either 0°, 45°, 90°, or 135°.

Detection of dynamically varying interaural time differences
2010Humans are highly sensitive to Interaural Time Differences (ITDs) in stimuli presented via headphones. For broadband noise stimuli of long durations, ITD detection thresholds can be as low as 10 to 15 ms. When the stimulus duration is shortened, thresholds increase by about a factor 2 for a tenfold decrease in duration.
