Background: it has been suggested that the function of the medial olivocochlear system (MOCS) can be evaluated by the suppression effect of the transient evoked otoacoustic emission (TEOAE). The competitive noise has an inhibitory effect on the functioning of the outer hair-cell, reducing the level of otoacoustic emissions. Despite the fact that there is no postnatal growth of the cochlea, midd...

Introduction Analysis of the suppression effect is a simple method to evaluate cochlear status and central auditory mechanisms and, more specifically, the medial olivocochlear system. This structure may be involved in the generation of mechanisms that cause tinnitus and in the pathophysiology of tinnitus in patients with tinnitus and normal hearing. Objective To review the literature of the eti...

This study verifies the effects of contralateral noise on otoacoustic emissions and auditory evoked potentials. Short, middle and late auditory evoked potentials as well as otoacoustic emissions with and without white noise were assessed. Twenty-five subjects, normal-hearing, both genders, aged 18 to 30 years, were tested . In general, latencies of the various auditory potentials were increased...

OBJECTIVE The aim of this study is to investigate otoacoustic emissions (OAEs) in young children with autism compared with those in an age-matched control group. MATERIALS AND METHODS Thirty-eight children with autism aged 3-6 years and 27 typically developing (normally developing) control subjects participated in this study. All the participants had normal hearing and middle-ear function. Au...

Multifrequency, complex-component tympanograms and transient evoked otoacoustic emissions (EOAEs) were recorded in 55 neonates less than 24 hours of age. The purpose of the investigation was to determine the normal middle ear immittance characteristics of neonates less than 24 hours old (the approximate discharge age of well-babies) and to assess whether an association exists between transient ...

introduction deafness is one of the most important sensory disturbances at birth. hearing loss can affect the development of speaking and learning during life. early diagnosis and intervention improve language outcome. the  current study aimed to determine the frequency of profound congenital hearing loss in healthy newborn infants in fars province. methods in a multicenter prospective study, f...

AIM This study was designed to investigate the function of outer hair cells and medial olivocochlear efferents in type II diabetes mellitus (DM). MATERIALS AND METHODS There were 50 patients with type II DM and 51 age- and sex-matched healthy controls included in the study. Both groups were compared in terms of transient evoked otoacoustic emissions (TEOAEs), distortion product otoacoustic em...
