The psychophysical and physiological assessment of cochlear-origin tinnitus
… of the results, the combination of the Distortion Product Otoacoustic Emission(DPOAE) level, Input/Output slope, and tinnitus handicap questionnaire scores indicated a possible measure of tinnitus severity, and the further statistical data analysis is required to confirm its …

A Comparison of Commercially Available Otoacoustic Emission Newborn Hearing Screening Devices
… ILO 88. Two of the screeners compared were distortion product otoacoustic emission (DPOAE) devices and two were transient evoked otoacoustic emission (TEOAE) devices. The AuDX, the GSI 70, and the EchoScreen are all automated pass/fail hearing screeners and were compared to the ILO 88, which …

Fine structure in distortion product otoacoustic emissions and auditory perception
Otoacoustic emissions (OAE) are emitted from a healthy ear and can be recorded in the sealed ear canal. The measurement of otoacoustic emissions is well established as a tool for hearing screening. However, until now OAE measurements allow no precise individual prediction of hearing status. The aim …

Objective Measures of Tinnitus in Humans
… various levels of the auditory system were used. Distortion product otoacoustic emission (DPOAE) input/output functions were calculated to assess cochlear function, contralateral suppression of reflectance-based stimulus frequency otoacoustic emissions was calculated to assess central auditory …

Responses from electric stimulation of cochlear nucleus
… The reflex was monitored through its effects on distortion product otoacoustic emission (DPOAE). The MOC reflex was activated bilaterally by stimulating PVCN or AVCN shell, but not AVCN core. These results suggest that there are two groups of MOC interneurons in specific parts of CN.

Investigation of acquired hearing loss in dopamine beta hydroxylase (DBH)-mutant mice
… measured auditory brainstem response (ABR) and distortion-product otoacoustic emission (DPOAE) thresholds, as well as sound-induced umbo velocity, and used standard histological techniques to study normal and pathological middle-ear anatomy. Anatomical analyses included observation of tympanic …

Mutation of SLC7A14 Causes Syndromic Hearing Loss
… indicative of progressive hearing loss. However, distortion product otoacoustic emission (DPOAE) measurements showed normal OHC function in wildtype and knockout mice. To confirm syndromic disease, alteration in auditory functions were examined in knockin mice with the missense mutation …

Early identification and monitoring of cochlear damage using extended high-frequency audiometry : a systematic review
… conventional audiometry (six studies – 37.5%) or distortion product otoacoustic emission (DPOAE) testing (two studies – 12.5%), or both methods (one study – 6.25%). Comparing EHF audiometry to conventional audiometry and DPOAE testing, the majority of the studies included in the systematic review …

Interactive effects of developmental PCB exposure and relevant environmental risks on the auditory system
… of the offspring was tested by measuring distortion product otoacoustic emissions (DPOAEs). DPOAE amplitudes were decreased and thresholds were elevated in the 6 mg/kg PCB group. Exposure to PBDEs alone did not cause DPOAE deficits. Importantly, there was an interactive effect from …

The efficacy of strategies used to minimise and prevent cisplatin ototoxicity in patients
… of Extended High Frequency Audiometry (EHF) and Distortion Product Otoacoustic Emission (DPOAE) testing into the monitoring protocol where possible to allow for early detection and intervention of ototoxicity. Incorporation of otoprotectors into the prevention protocol is suggested as they have …
