High-side suppression diminishes or disappears with age
Evidence
There is psychoacoustic evidence that suppression measured with suppressors above the signal frequency (high-side suppression) and below the signal frequency (low-side suppression) may show different aging effects. — Dijk, Pim van, Physiology, Psychoacoustics and…, 921
Categorization
- XREF: Connects to the reader’s broader interest in how cochlear nonlinearity degrades with age, distinct from pure threshold elevation. — connects to: Band-widening suppression studies show inconsistent age effects on suppression; Outer-hair-cell damage raises high-side but not low-side suppression thresholds.
- corroborated: 2 independent passages support this claim — Dijk, Pim van, Physiology, Psychoacoustics and…, 921
