Older adults lose measurable suppression entirely when maskers are long

Evidence

With the short combined masker, all participants showed some low-side suppression, and all participants except for one older adult showed high-side suppression. With the long combined masker, 2/5 older adults had no measurable low-side suppression, and 3/5 older adults had no measurable high-side suppression. — Dijk, Pim van, Physiology, Psychoacoustics and…, 949

• QUESTION: Why would masker duration interact so sharply with age — is the loss of suppression with long maskers best explained by cochlear compression loss or central adaptation?
