The characteristic of otoacoustic emissions in full-term neonates according to ABO blood groups

open access: yesBrazilian Journal of Otorhinolaryngology, 2020
Introduction: Previous research has suggested that individuals with different blood groups show varied incidences of noise-induced hearing loss. The reduced otoacoustic emissions amplitudes indicate the higher possibilities of outer hair cell damage for ...

Otoacoustic Emissions in Smoking and Nonsmoking Young Adults [PDF]

open access: yesClinical and Experimental Otorhinolaryngology, 2015
ObjectivesThe present study investigates the usefulness of transiently evoked otoacoustic emissions (TEOAEs) and distortion product OAEs (DPOAEs) in detecting small changes in the hearing of young smoking adults.MethodsOtoacoustic emissions were acquired

Ototoxicity and otoprotection in the inner ear of guinea pigs using gentamicin and amikacin: ultrastructural and functional aspects

open access: yesBrazilian Journal of Otorhinolaryngology, 2008
Summary: Ototoxicity is still a challenge to medicine. The discovery of self-protecting endogenous mechanisms of the outer hair cells associated with their functional and ultra-structural assessment methods has opened new horizons in the understanding ...

Synchronization of Spontaneous Active Motility of Hair Cell Bundles. [PDF]

open access: yesPLoS ONE, 2015
Hair cells of the inner ear exhibit an active process, believed to be crucial for achieving the sensitivity of auditory and vestibular detection. One of the manifestations of the active process is the occurrence of spontaneous hair bundle oscillations in

Relating the variability of tone-burst otoacoustic emission and auditory brainstem response latencies to the underlying cochlear mechanics [PDF]

open access: yes, 2015
Forward and reverse cochlear latency and its relation to the frequency tuning of the auditory filters can be assessed using tone bursts (TBs). Otoacoustic emissions (TBOAEs) estimate the cochlear roundtrip time, while auditory brainstem responses (ABRs ...

Efferent auditory system: its effect on auditory processing

open access: yesBrazilian Journal of Otorhinolaryngology, 2008
Summary: Auditory processing depends on afferent and efferent auditory pathways integrity. The efferent auditory system may be assessed in humans by two non-invasive and objective methods: acoustic reflex and otoacoustic emissions suppression.

Spectral instabilities of spontaneous otoacoustic emissions. [PDF]

open access: yesThe Journal of the Acoustical Society of America, 1991
Attempts to model spontaneous otoacoustic emissions (SOAEs) have generally posited as self-sustained oscillators that are perturbed by noise [cf. Talmadge etal., J. Acoust. Soc. Am. 89, 2391–2399 (1991)]. The critical data against which to evaluate such models, based on short-term statistical variations in the frequency and amplitude, have been ...

Brainstem auditory evoked responses in an equine patient population: part I--adult horses. [PDF]

open access: yes, 2014
BackgroundBrainstem auditory evoked response has been an underused diagnostic modality in horses as evidenced by few reports on the subject.Hypothesis/objectivesTo describe BAER findings, common clinical signs, and causes of hearing loss in adult horses ...

Acquisition and Repeatability of High-Frequency Distortion Product Otoacoustic Emissions Using Two Different Calibration Methods in Newborns

open access: yesApplied Sciences, 2019
Distortion-product otoacoustic emissions (DPOAEs) elicited with high-frequency (HF; up to 16 kHz) stimuli are measurable and repeatable in normal-hearing adults and children, adult patients, and are sensitive to ototoxic insults in adults.
