摘要: A forward masking technique was used to measure cochlear gain reduction which might be consistent with the medial olivocochlear reflex (MOCR). 4-kHz signal set at 20 dB SL, and an on-frequency masker adjusted just mask signal. Adding a pink noise precursor before increased level of needed signal, in contrast what would expected from theories such as additivity masking. The magnitude pattern this increase similar threshold seen off-frequency following precursor.
