I think I've got a pretty good sense of many of them. Do you find that some posters' first impressions are very different from what you perceive after a few months?
Perhaps you project your voice so that it reaches the back of the room? (My daughter & SIL practically shout during conversations, though the pandemic's online schooling has helped bring down their everyday volume.)
Haven't they changed theaters enough yet
(with technology and microphones, etc, not the building designs)
in recent decades,
so that actors would not need to project their voices as much, and cause damage for some of their throats?
