Such pills are coming ever closer to reality. Researchers at the University of Michigan Kresge Hearing Research Institute found that a cocktail of vitamins A, C and E, plus magnesium was able to prevent hearing loss from noise exposure prevented about 80 percent of possible hearing loss in guinea pigs. Now they have launched human tests of this cocktail, branded AuraQuell. Human tests are being done in military, industrial, and loud music exposure settings.
AuraQuell was able to be developed because of an earlier scientific discovery that loud noise exposure triggered the production of molecules that damaged the inner ear hair cells, resulting in hearing loss. Growth of these molecules is prevented by the AuraQuell cocktail.
We could soon see a future in which soldiers about to head onto the battlefield take a pill or eat a special "candy" bar, people heading to jobs in the factory take a pill, or parents ask their teenagers about to leave for a concert, "did you take your hearing loss prevention pill?"
