Apparent spatial deficits in hearing loss may really be audibility deficits

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

Categorization

• SEED: A hearing-aid design angle: if SRM deficits are audibility-driven rather than spatial-mechanism-driven, fitting strategy changes meaningfully.
• corroborated: 5 independent passages support this claim — Dijk, Pim van, Physiology, Psychoacoustics and…, 1722
• XREF: connects to: Elevated hearing thresholds impair spatial separation of direct sound from room reflections.; Reduced target audibility, not spatial processing loss, explains much of the hearing-loss speech deficit — Dijk, Pim van, Physiology, Psychoacoustics and…, 1719; Hearing-impaired deficits persist even when only energetic glimpses are presented (+4 more)
