Room absorption and source directivity shift the critical distance only by their square roots

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 (#qualifies, via linked claim)
