Interaural phase differences can produce time-delay sensations measured at threshold.

Evidence

Time delay in this context is often thought of as being the delay between the onset of a click, of a tone burst, or of some other short impulsive sound. Another way to produce a delay using steady-state sinusoidal tones is to produce a phase shift between the two ears. If the phase of a tone presented to one ear is different from that of a tone of the same frequency presented to the other ear, the time delay produces a sensation from which threshold can be measured. — Professor Dr.-Ing.

• DEFINE: Clarifies that interaural time delay can be created not only by onset delays of impulsive sounds but by steady-state phase shifts between the ears — a core methodological concept for binaural psychoacoustics.
