Hearing loss patient has sharper category boundaries than the compression suggests

Evidence

Listener HL11 (4th row) has LDL that is within the ranges of a NH listener; the higher threshold level causes the spacing between category boundary curves to be compressed horizontally. Despite this compression, this listener with HL has well-defined perceptual boundaries between categories (i.e., sharply-sloped boundary curves). — Dijk, Pim van, Physiology, Psychoacoustics and…, 2549 (#corroborates, via linked claim)
