Elevated hearing thresholds impair spatial separation of direct sound from room reflections.
Evidence
Finally, it has been observed that SRM is often inversely related to the severity of hearing loss (e.g. Marrone et al. 2008 ). This raises the question of whether in some cases apparent spatial deficits might be related to reduced audibility in spatialized mixtures. — Dijk, Pim van, Physiology, Psychoacoustics and…, 1722 (

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 (
