Cinema RT targets balance dialog clarity against realistic hall ambience.
Evidence
Cinemas exhibit mid-frequency RTs of 0.3 s to 0.6 s for good dialog intelligibility, and so that the acoustics of the often-large venue displayed on the screen will can be convincingly delivered. In terms of speech intelligibility, anything below 0.5 s is considered to be safe, but the elevated RTs seen at low frequencies can amplify lower vocal formants, causing chestiness. — Toole, Floyd E, Sound reproduction- the acoustics and…, 1240
