Otoacoustic Emission in Tinnitus Patients
نویسندگان
چکیده
The purpose of the study was to determine the effect of tinnitus and total effect of tinnitus and the hearing loss function on the distortion product otoacoustic emission. Tinnitus patients were selected to exhibit normal hearing and such tinnitus patients who exhibited the increasing or notch-like sensorineural hearing loss. It was found that the cochlear hearing activity expressed in terms of DPOAE response differed between tinnitus patients and normal-hearing subjects. The DPOAE levels in the tinnitus patients with normal hearing threshold have been lower than those in the nontinnitus subjects. The differences depended on the frequency and the age of the patients suggesting the effect of presbyacusis.

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 (...

UNLABELLED The workings of the auditory pathway of patients with tinnitus and normal hearing can be associated with an auditory efferent pathway dysfunction at the level of the superior olivary complex. Otoacoustic emission suppression with contralateral noise can represent an alternative to its evaluation. AIM to investigate Transient Otoacoustic Emission suppression in normal hearing adults...

INTRODUCTION The medial olivocochlear bundle effect is studied through the suppression of otoacoustic emissions and seems to be influenced by the laterality of the central nervous system, presenting no symmetry between right and left ear. A dysfunction of this bundle may be involved in the generation of tinnitus, although this fact was not confirmed. OBJECTIVES Study the suppression of distor...
