Temporal fine-structure sensitivity correlates with brainstem encoding and speech-in-noise ability

Evidence

The overall aim of this study was to examine the relationships between perceptual sensitivity to temporal fine-structure cues, brainstem encoding of complex harmonic and amplitude-modulated sounds, and the ability to understand speech in noise. Understanding these links will allow the development of an objective measure that could be used to detect changes in functional hearing before the onset of permanent threshold shifts. — Dijk, Pim van, Physiology, Psychoacoustics and…, 4161

Categorization

• QUESTION: The premise that functional-hearing decline can be detected before permanent threshold shift implies a staged cascade — when in noise exposure does TFS encoding degrade relative to audiometric thresholds?
• corroborated: 2 independent passages support this claim — Dijk, Pim van, Physiology, Psychoacoustics and…, 4161
