Purpose Distortion product otoacoustic emissions (DPOAEs) and audiometric thresholds have been used to account for the impacts of subclinical outer hair cell (OHC) dysfunction on auditory perception measures physiology. However, relationship between DPOAEs audiogram is unclear. This study investigated this by determining how well DPOAE levels can predict among individuals with clinically normal...

OBJECTIVES To determine whether patients with vestibulotoxic reactions to gentamicin have hearing thresholds worse than predicted by distributions of better-ear hearing thresholds in people of the same age and sex in the general population, and, if so, to measure the severity and audiometric pattern of that hearing loss. DESIGN Retrospective case series from previously published prospective a...

Presbycusis and noise-induced hearing loss result in characteristic audiogram curves with increasing levels of at higher frequencies. Another specific form curve is the cookie bite, which often inherited sometimes illness or injury. The influence on speech intelligibility was examined along a list words selected according to frequency range phonemes present. Dependence dominant loss, lower, mid...

Multiple auditory steady-state responses were evoked by eight tonal stimuli (four per ear), with each stimulus simultaneously modulated in both amplitude and frequency. The modulation frequencies varied from 80 to 95 Hz and the carrier frequencies were 500, 1000, 2000, and 4000 Hz. For air conduction, the differences between physiologic thresholds for these mixed-modulation (MM) stimuli and beh...
