Air absorption in rooms under 40 cubic meters is acoustically negligible

Evidence

The sound field in small listening rooms is not diffuse, statistical acoustics do not apply, and there is no critical distance, as classically defined. — Toole, Floyd E, Sound reproduction- the acoustics and…, 1312 (#corroborates, via linked claim)
