Guinea pigs exposed to a loud, continuous noise may show the way for a nutrient treatment to reduce hearing loss.
A University of Michigan study on guinea pigs showed that a combination of high doses of vitamins A, C and E, along with magnesium, was very effective at preventing hearing damage from loud noises.
One group of the animals was given a dose an hour before being subjected to a 120-decibel-level noise (about the same as a jet engine at takeoff) for five hours. The guinea pigs then received the same dose daily for five days afterward, and testing showed "significantly less noise-induced hearing loss than the other groups,'' according to a press release on the study.
Clinical trials could start soon for a snack bar or pill to protect soldiers, workers and musicians who are exposed to loud noises, the statement said. Marianne Rzepka, News staff reporter
