Perceived loudspeaker sound quality depends only on amplitude responses

Evidence

All dimensions perceived in the performed listening tests correspond with features extracted from the sound pressure response of the diffuse and direct field at the listener’s position. There was no hint of a relation to phase response or to nonlinear distortion. — Toole, Floyd E, Sound reproduction- the acoustics and…, 711
