otoacoustic emissions


Also found in: Acronyms.

otoacoustic emissions

echoes emitted by the outer hair cells of the inner ear. These echoes are used to evaluate the integrity of the inner ear and to screen hearing in newborns.

On the other hand, 79 cases (158 ears) of the 134 patients with complete data of DP otoacoustic emission test were selected as an AN2 group, which was compared with 30 normal subjects (60 ears) regarding the results of DP otoacoustic emission test.
The inclusion criteria were age >10 months and <72 months with a speech delay based on the early language milestone criteria (ELM) for children <3 years old and the Peabody Picture Vocabulary Test-Revised criteria for children >3 years old and normal routine auditory tests like behavioral auditory, impedance audiometry, and distortion-product otoacoustic emission (DPOAE) tests as well as normal neurological examinations by a neurologist.

The otoacoustic emissions (OAE) technology delivers clicks or tone bursts through the newborn's ear canal via a probe inserted into his or her ear.
A more definitive study would test patients' hearing, including the attainment of extended high frequencies (beyond 8000 Hz), measurement of otoacoustic emissions, immittance testing, and speech testing, before (baseline testing) and after they started using the medication.
As outer hair cells become permanently damaged or nonfunctional, otoacoustic emissions provide greater accuracy and efficiency in predicting cochlear status than the audiogram.
At 45 months, the children also underwent otological and auditory testing, including an assessment of distortion product otoacoustic emissions (DPOAEs), a measure of cochlear function.
To determine how the inner ear responded to the signal, the researchers took advantage of a phenomenon referred to as spontaneous otoacoustic emissions (SOAEs).
This form of telemedicine can be used to interpret video otoscopy, audiometry, immittence, otoacoustic emissions, and auditorybrainstem response readings.
There are two methods by which new born hearing screening is done -- otoacoustic emissions (OAE) and automated auditory brain stem responses (BR).
