Pure-tone thresholds capture hearing aspects that speech reception thresholds miss

Evidence

The results for PTA are somewhat surprising given that all speech testing was done at sensitivity-adjusted levels, which might have been expected to equate for PTA differences. The PTA measure may therefore capture some aspect of hearing that is not well represented by SRT. — Dijk, Pim van, Physiology, Psychoacoustics and…, 1229

• QUESTION: What aspect of hearing beyond the speech reception threshold does the pure-tone average still capture after sensitivity adjustment? Worth chasing the mechanism literature.
