Abstract

Noise-induced hearing loss could be caused by mechanical destruction of the delicate membranes of the inner ear, hair cells and supporting structures of the organ of Corti, and by intense metabolic activity, which increases free radical formation in the cochlea. When exposure is continuous, injury is a consequence of the total amount of energy to which cochlear tissues are exposed and a hearing conservation program is essential including hearing protection devices. Several therapeutic trials including antioxidant agents have been shown at least partially effective in prevention of hearing loss and hair cell death.
