The brain possesses a remarkable capacity to compensate for changes in inputs resulting from a range of sensory impairments. Developmental studies of sound localization have shown that adaptation to asymmetric hearing loss can be achieved either by reinterpreting altered spatial cues or by relying more on those cues that remain intact. Adaptation to monaural deprivation in adulthood is also pos...

The main objective of this study is to provide an overview of the basic mechanisms of blast induced hearing loss and review pharmacological treatments or interventions that can reduce or inhibit blast induced hearing loss. The mechanisms of blast induced hearing loss have been studied in experimental animal models mimicking features of damage or injury seen in human. Blast induced hearing loss ...

Because hearing is accomplished by the brain (with neural input from the cochlea), presbyacusis can be ultimately accounted for by changes in brain activity that accompany aging. The anatomic and physiologic changes that accompany aging are of two basic types: the central effects of biological aging (CEBA) and the central effects of peripheral pathology (CEPP). Research using inbred mice and ot...

improvements in science and technology and the use of modern machinery in manufacture have led to increase in the number of workers exposed to hazardous agents including noise. this study evaluated the effects of occupational noise on hearing loss and blood pressure in welders after 4 years.in this cohort study, all of the welders working at one of neyshabur's water heater producing factories w...

background: hearing loss due to chronic otitis media is common. the purpose of this study was to evaluate hearing before and after canal wall up, canal wall down mastoidectomy and tympanoplasty. methods: from 2004 to 2007, all patients with chronic otitis media who were admitted at the department of otolaryngology, babol medical university were studied. for 126 patients' canal wall up, can...
