Medial olivocochlear reflex requires roughly 20-70 ms of sound to engage.

Evidence

Masker durations were 20 (short) and 70 ms (long). The 20-ms masker should be too short to elicit the MOCR, while the 70-ms masker should be long enough to elicit full gain reduction from MOCR elicitation (Roverud and Strickland 2010 ). — Dijk, Pim van, Physiology, Psychoacoustics and…, 927

Medial olivocochlear inhibition is stronger apically and shifted half an octave
Medial olivocochlear reflex suppression requires maskers longer than 20 ms
Prior suppression studies may be confounded because long stimuli trigger the medial olivocochlear reflex
The efferent olivocochlear reflex takes 25-40 ms to begin acting
