Head-shadow ILDs and efferent gain inhibition combine to drive the cocktail-party effect

Evidence

The present analysis shows that this role manifests during ‘free-field’ listening and results from a combination of head-shadow frequency-specific ILDs with frequency-specific contralateral MOCR inhibition of cochlear gain. — Dijk, Pim van, Physiology, Psychoacoustics and…, 1939
