Continuing with our senses theme from earlier in the day, we'd also like to direct you to some information concerning sound and hearing. Two recent animal studies, backed by the National Institute on Deafness, have demonstrated that temporary noise-induced hearing loss can be prevented by a combination of the antioxidants beta-carotene, vitamins C and E, and magnesium. There is some evidence that these nutrients may work to protect a structure in the ear which is related to the hearing loss issues of advanced age, though these findings were more tenuous.
Repeated incidents of temporary noise-induced hearing loss can lead to permanent hearing loss, and researchers have now begun more extensive studies to determine the relationship between these two types of hearing damage.
