Room resonances shift from isolated to overlapping at the Schroeder frequency
Evidence
If the anechoic loudspeaker data do not reveal evidence of resonances, fluctuations in steady-state room curves are almost certainly attributable to acoustical interference. It is highly improbable that the propagation path from the loudspeaker to the microphone/listener contains a potent acoustical resonance mechanism above the transition frequency. — , Toole, Floyd E - Sound reproduction-…, 412 (
