Group delay audibility threshold is 1.6 to 2 milliseconds

Evidence

By comparing the timing and intensity of a sound at each ear, listeners can locate its source on the horizontal plane, and exploit these differences to hear out signals in background noise—an important component of ‘cocktail party listening’. Sensitivity to interaural time differences (ITDs) in particular has received much attention, due in part to the exquisite temporal performance observed; for sound frequencies lower than about 1.3 kHz, ITDs of just a few tens of microseconds are discriminable, observed both at the neural and behavioural levels. — Dijk, Pim van, Physiology, Psychoacoustics and…, 2949 (#complicates, via linked claim)
