BACKGROUND The Bluetooth wireless headset has been promoted as a 'hands-free' device with a low emission of electromagnetic radiation. OBJECTIVE To evaluate potential changes in hearing function as a consequence of using Bluetooth devices, by assessing changes in pure tone audiography and distortion production otoacoustic emissions. DESIGN Prospective study. MATERIALS AND METHODS Thirty a...

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 tympanostomy tube insertion by Distortion Product Otoacoustic Emission (DPOAE) and Transient Evoked Otoacoustic Emission (TEOAE) as methods of evaluation of postoperative hearin...

Otoacoustic emissions, sounds generated in the inner ear, have become a convenient non-invasive tool to examine the efferent modulation of cochlear mechanics. Activation of the medial olivocochlear (MOC) efferents has been shown to alter the magnitude of these emissions. When the effects of efferent activation on the detailed spectral structures of these emissions have been examined, a shift of...

UNLABELLED The hormonal changes that occur in a short time span promote modifications all over the woman's body, with physical and emotional manifestations which are frequently observed. AIM to evaluate the activity of the external ciliated cells in women during their menstrual cycle, observing the effect of hormonal changes caused by the cycle in their 3 phases. METHODS this is a longitudi...

The clinical measurement of otoacoustic emissions can assist in differentiating between peripheral and central explanations for deficits in speech understanding. We present audiometric and distortion-product emission data in a case with sensorineural hearing loss and a deficit in speech understanding . The presence of evoked emissions argues against attributing the speech audiometric loss to co...
