OBJECTIVE To determine whether there is any influence of systemic arterial hypertension on the peripheral auditory system. METHODS This was a cross-sectional study that investigated 40 individuals between 30 and 50 years old, who were divided into groups with and without systemic arterial hypertension, using data from high-frequency audiometry, transient-evoked otoacoustic emissions and disto...
Background: Different studies have shown that Otoacoustic Emission (OAEs) is generated by Outer Hair Cells (OHCs) and these sensory cells are first structures exposed to damage of high level noise. Therefore minor impairment in OHCs can lead to lack of response of OAE. The purpose of the current study is to compare the pure tone thresholds, Transient Evoked Otoacoustic Emission (TEOAE...
UNLABELLED Exposure to loud music is increasing among young people, and so could be the number of hearing impairment cases in this population. Otoacoustic emission tests are sensitive in capturing the effects of exposure to noise, and allow the detection of early cochlear disorders. OBJECTIVE This study aims to look into the prevalence rates of injuries to outer hair cells in a population of ...
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 (...
Introduction The most commonly used method in neonatal hearing screening programs is transient evoked otoacoustic emissions in the first stage of the process. There are few studies comparing transient evoked otoacoustic emissions with distortion product, but some authors have investigated the issue. Objective To correlate the results of transient evoked and distortion product otoacoustic emissi...
OBJECTIVE To correlate the annoyance of tinnitus assessed by the Tinnitus Handicap Inventory and on a visual analogue scale with the evoked otoacoustic emission test result in tinnitus patients with normal hearing. STUDY DESIGN Case-control study. SETTING Public tertiary hospital. SUBJECTS AND METHODS The sample was initially based on a population of 80 subjects with tinnitus; 20 of them ...
Introduction: Otoacoustic emissions are low density sounds produced from intact cochlea measureable in the presence of an intact conduction structure. The goal of this study was to assess the surgical success rate after stapes surgery by standard audiometric tests, Distortion Product Otoacoustic Emission (DPOAE) and Transient Evoked Otoacoustic Emission (TEOAE) as methods of evaluation of post...
OBJECTIVES To determine the output levels of a commercially available MPEG layer-3 (MP3) player and to evaluate changes in hearing after 1 hour of listening to the MP3 player. DESIGN First, A-weighted sound pressure levels (measured in decibels [dBA]) for 1 hour of pop-rock music on an MP3 player were measured on a head and torso simulator. Second, after participants listened to 1 hour of pop...
