Listener ‘clarity’ ratings correlate with intelligibility but are not a direct measure

Evidence

Shirley and Kendrick (2004) investigated the effects of differing amounts of “extra” sound on listener impressions of dialogue clarity, overall sound quality and enjoyment. Clarity is a quality that corresponds to intelligibility, although it is not a direct quantitative measure of that parameter. Some of their listeners had measurably normal hearing, while others had varying degrees of impairment. — Toole, Floyd E, Sound reproduction- the acoustics and…, 1907
