Evaluation of Distortion and Transient Evoked Otoacoustic Emission in Tinnitus Patients with Normal Hearing
Introduction: Tinnitus is a perception of sound without external source. The exact etiology of tinnitus is not fully understood, although some researchers believe that the condition usually starts in the cochlea. The aim of this study was to determine the potential contribution of outer hair cell dysfunction to chronic tinnitus, by application of Distortion-Product Evoked Otoacoustic Emission (...
متن کاملSwept - Tone Evoked Otoacoustic Emissions: Stimulus Calibration and Equalization
of a thesis at the University of Miami. Master’s thesis supervised by Professor Ozcan Ozdamar. No. of pages in text. (53) Otoacoustic Emissions (OAE) are minute acoustic responses originating from the cochlea as a result of an external acoustic stimulus and are recorded using a sensitive microphone placed in the ear canal. OAEs are acquired by synchronous stimulation with an acoustic click or t...
متن کاملhearing status in neonatal hyperbilirubinemia by auditory brain stem evoked response and transient evoked otoacoustic emission
hyperbilirubinemia at neonatal period is one of the major deteriorating factors of the auditory system. if left untreated, it may cause certain cerebral damage. this study aims to evaluate the impact of hyperbilirubinemia on the hearing of neonate. this study was conducted on 35 newborn babies with jaundice (bilirubin more than 20 mg/dl). auditory brainstem response (abr) and transient evoked o...
متن کاملTransient Evoked Otoacoustic Emission in Neonates with and without Vernix
Transient evoked otoacoustic emissions (TEOAEs) are not necessarily recordable in all healthy neonates, before discharge, due to transient conditions (such as vernix in ear canals). To determine the possibility and feasibility of screening of very young newborns before discharge from hospital (JCIH, 2007), it is important to know how vernix in external ear during this time affects screening res...
متن کاملSignificance of a notch in the otoacoustic emission stimulus spectrum.
OBJECTIVE To explain a clinical observation: a notch in the stimulus spectrum during transient evoked otoacoustic emission measurement in ears with secretory otitis media. METHODS The effects of tympanic under-pressure were investigated using a pressure chamber. A model of the ear canal was also studied. RESULTS Tympanic membrane reflectance increased as a consequence of increased stiffness...
