Room effects minimally influence steady-state response above 1 kHz
Evidence
Above about 1 kHz the curves agree very well, indicating minimal room effects. The curves were normalized to this frequency range. Below about 150 Hz the variations are of a kind expected for differing amounts of reflected energy, adjacent boundary effects and, in the smaller venues, room modes. — Toole, Floyd E, Sound reproduction- the acoustics and…, 1331
