Acoustical interference is non-minimum-phase but less audible than resonances.

Evidence

However, once the sound has left the loudspeaker system, phase, by itself, turns out not to be a significant audible factor. Because both amplitude and phase information are needed to describe sound pressure as a function of time, this means that we really don’t hear waveforms. Incredible? … Phase shifts and even complete polarity inversions turn out to be “is it there or not?” subjective issues when tested in blind circumstances. Using contrived signals in headphone or anechoic listening, some listeners report hearing a “difference,” but a reliably stated “preference” has been elusive. In normally reflective rooms using music, the differences, if real, become vanishingly small or non-existent. — , Toole, Floyd E - Sound reproduction-…, 504 (#corroborates, via linked claim)
