Wider stimulus bandwidths improve listeners’ ability to detect temporal gaps

Evidence

If a patient were to have a high gap detection threshold, we have to ask, “Is the gap detection threshold high because the patient can’t hear it? Or is it because of poor temporal processing?” This is a problem if this test were used diagnostically in isolation — a high gap detection threshold does not automatically imply poor temporal processing, particularly if the patient has a hearing loss. — Jennifer Lentz, Psychoacoustics- Perception of Normal…, 965 (#corroborates, via linked claim)
