Binaural hearing transforms in-room comb filtering into perceived spaciousness

Evidence

Comb filtering is often thought to be involved in all delayed sounds. However, a delayed sound arriving from a different horizontal angle than the direct sound is perceived as spaciousness, not comb filtering. It adds to the information about the room. — , Toole, Floyd E - Sound reproduction-…, 729 (#corroborates, via linked claim)

Beyond the first few rows in a concert hall, most of what one hears is reflected sound. Two ears and a brain, binaural hearing, in the live venue are able to separate the direct sound from later arrivals: the sound source from the room (Section 1.6). A microphone at the same location combines them, without discrimination, so such recordings, when replayed, sound far too reverberant. This is why recordings are made using different techniques, with multiple microphones closer to the instruments and voices. To record successfully in audience locations one needs binaural methods (Section 3.3). — Toole, Floyd E, Sound reproduction- the acoustics and…, 376 (#expands, via linked claim)
