Medial olivocochlear reflex suppression requires maskers longer than 20 ms
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
