Reports on the finding that otoacoustic emissions may actually produce a type of hearing loss that occurs without physical damage to any parts of the ear. Evidence from chinchillas, rodents with hearing range similar to that of humans; Effects of the otoacoustic emissions from chinchilla's ears on its hearing; Details of the study by psychologist Richard Salvi and his colleagues at the Buffalo-based State University of New York.

    Transiently evoked otoacoustic emissions (TEOAEs) without and with contralateral acoustical stimulation, were recorded on 52 subjects ranging from 20 to 78 years. Subject selection was based on the hearing levels from 0.5 to 4 kHz being better than 25 dB HL, normal tympanograms and stapedial...

    Abstract The aim of this series was to assess hearing screenings; auditory brainstem responses (ABR), transient evoked otoacoustic emissions (TEOAE) and free field auditory responses (FF) for the prediction of permanent bilateral hearing loss in high-risk preterm infants at term...

    We measured otoacoustic emissions in anesthetized chinchillas evoked by short (1 ms) high-frequency (4 kHz) tone-pips (TEOAE) using either a compression or suppression method to separate the stimulus from the emission. Both methods revealed consistent features of the TEOAEs. The main spectral...

  • Modeling OAE Responses to Short Tones. Duifhuis, Hendrikus; Siegel, Jonathan // AIP Conference Proceedings;2015, Vol. 1703 Issue 1, p1 

    In 1999 Shera and Guinan postulated that otoacoustic emissions evoked by low-level transient stimuli are generated by coherent linear reflection (CRF or CLR). This hypothesis was tested experimentally, e.g., by Siegel and Charaziak[10] by measuring emissions evoked by short (1 ms) tone pips in...

    Otoacoustic emissions evoked with transient sounds (TEOAEs) are believed to originate within the tonotopic region of the stimulus in the cochlea via the same mechanisms as emissions evoked with single tones. However, we found that emissions evoked by low frequency (< 3 kHz) single-tones have an...

    The present study investigates the effect of small amounts of outer hair cell (OHC) loss on distortion product otoacoustic emission (DPOAE) levels and evoked potential permanent threshold shifts (PTS) in a population of 12 noise-exposed chinchillas. The group mean DPOAE level, which decreased by...

    Distortion product otoacoustic emissions are one form of evoked otoacoustic emissions. DPOAEs provide the frequency specific information about the hearing status in mid and high frequency regions. But in most screening protocols TEOAEs are preferred an it requires less time compared to DPOAE....

    This article describes the results of otoacoustic emissions testing in five patients with sensorineural hearing loss. We conducted an audiologic evaluation and performed image and cerebral function studies on each patient. Our investigation revealed that all five had spontaneous otoacoustic...
