while most tinnitus cases have some degree of hearing impairment, a small percent of the patients admitted to ear, nose and throat clinics or hearing evaluation centers are those who complain of tinnitus despite having normal hearing thresholds. present study was performed in order to better understanding of the probable causes of tinnitus and to investigate possible changes in the cochlear and...

abstract   introduction: conductive hearing loss attenuates and delays sound transmission in the middle ear. it can make variety of central auditory processing disorders; that persists even after resolve of peripheral auditory system problems. one of the aspects of central auditory processing is the temporal processing, which is important for understanding speech, including temporal resolution,...

normal 0 false false false en-us x-none ar-sa background: considering the presence of squamous epithelial cells and fibroblasts in the tympanic membrane (tm), topical estrogen application may influence the repair of tm perforations. therefore, this study was designed to investigate the healing effect of topical estrogen on chronic tm perforations and improvement in hearing threshold. materials ...

Background: Previous studies showed that one of the complications of rheumatoid arthritis disease was auditory disorder. The goal of the present study was to compare the auditory status in patients with rheumatoid arthritis and healthy individuals. Methods: In the present case-control study, 30 normal persons and 60 persons with rheumatoid arthritis with mean age of 46.72 and standard deviatio...

introduction: neonatal hyperbilirubinemia is one of the most important factors affecting the auditory system and can cause sensorineural hearing loss. this study investigated the relationship between behavioral hearing thresholds in children with a history of jaundice and the maximum level of bilirubin concentration in the blood.   materials and methods: this study was performed on 18 children ...

introduction: hearing loss is one of the most common occupational diseases. in most workplaces, workers are exposed to noise and solvents simultaneously, so the potential risk of hearing loss due to solvents may be attributed to noise.  in this study we aimed to assess the effect of exposure to mixed aromatic solvents on hearing in the absence of exposure to hazardous noise.   materials and met...

Background: Many elderly individuals complain of difficulty in understanding speech in noise despite having normal hearing thresholds. According to previous studies, auditory training leads to improvement in speech-in-noise perception, but these studies did not consider the etiology, so their results cannot be generalized. The present study aimed at investigating the effectiveness of envelope-b...
