The human efferent reflex to sound has an onset delay of 25-40 ms
Evidence
The human MOCB response (as measured using otoacoustic emissions: OAEs) has an onset delay of between 25 and 40 ms and rise and decay time constants in the region of 280 and 160 ms, respectively (Backus and Guinan 2006 ). — Dijk, Pim van, Physiology, Psychoacoustics and…, 5953
