Hearing loss often results in tinnitus and auditory cortical map changes, leading to the prevailing view that the phantom perception is associated with cortical reorganization. However, we show here that tinnitus is mediated by a cortical area lacking map reorganization. High-frequency hearing loss results in two distinct cortical regions: a sensory-deprived region characterized by a decrease i...

Neural mechanisms that detect changes in the auditory environment appear to rely on processes that predict sensory state. Here we propose that in tinnitus there is a disparity between what the brain predicts it should be hearing (this prediction based on aberrant neural activity occurring in cortical frequency regions affected by hearing loss and underlying the tinnitus percept) and the acousti...

Individuals with sensorineural hearing loss have difficulty understanding speech, especially in background noise. This deficit remains even when audibility is restored through amplification, suggesting that mechanisms beyond a reduction in peripheral sensitivity contribute to the perceptual difficulties associated with hearing loss. Given that normal-hearing musicians have enhanced auditory per...

Introduction The paramount goal for subjects with sensory-neural hearing loss is to make as precise a distinction as possible among the different sites in the sensory system where a casual lesion may lie. The usual tests of conventional audiometry· viz., pure tone sensitivity measures; tests of recruitment and abnormal tone decay; Bekesy audiometry; speech audiometry; stapedius reflex measureme...

Recent studies in normal-hearing listeners have used envelope-vocoded stimuli to show that the masking of speech by noise is dominated by the temporal-envelope fluctuations inherent in noise, rather than just overall power. Because these studies were based on vocoding, it was expected that cochlear-implant (CI) users would demonstrate a similar sensitivity to inherent fluctuations. In contrast,...

With the introduction of newborn hearing screening, infants are being diagnosed with hearing loss during the first few months of life. For infants with a sensory/neural hearing loss (SNHL), the audiogram can be estimated objectively using auditory brainstem response (ABR) testing and hearing aids prescribed accordingly. However, for infants with auditory neuropathy spectrum disorder (ANSD) due ...

BACKGROUND Multiple sclerosis (MS) has numerous neurologic signs and symptoms, including hearing impairment. The reports concerning the type and severity of hearing loss in MS patients vary and little is known about an association of the disease characteristics with changes in hearing status. OBJECTIVE To find the otologic and neuro-otologic manifestations of MS with the use of routine hearin...

Unhealthy ears may cause hearing loss. This issue affect children to have difficulty communicating with others and decrease learning achievement at school. community service activity aimed give knowledge about loss conduct examinations in orphanage children. was held the Aulia Al-Ikhlas Orphanage Sungai Pagar Village, Kampar Kiri Hilir District, Regency, Riau. At beginning of activity, we provi...

background & objectives: the purpose of this study was evaluating the hearing status of tinnitus patients referred to our center. materials & methods: a total of 144 patients, referred to our center by the end of december 2008 to june 2009, who have tinnitus complaints after initial examination and cleaning the ear duct in the audiology clinic were introduced and completed the questionn...
