Protect your ears from loud noises with N-acetylcysteine (NAC).

Hear No Evil

NAC prevents permanent eardrum damage due to loud sounds.
Two studies here and here show that taking N-acetylcysteine (NAC) after being exposed to loud noises can prevent noise-induced hearing loss (NIHL). In the first study, Col. Richard Kopke, M.D., the study's director, demonstrated that 900MG of NAC prevented "temporary cochlear changes" in humans when exposed to 102 decibles (dB) (the same as a jackhammer, and louder than a lawnmower) using a 2 kHz tone (a medium-pitched sound) for ten minutes. The second study exposed 18 small rodents to an extremely high sound level of 155 dB for 150 repetitions. The animals that got NAC showed significantly reduced hearing loss.

Shearing forces caused by any sound have an impact on the stems of the hair cells of the basilar membrane of the cochlea (the inner ear), and if excessive these forces can cause cell death.

NAC works in protect the ear due to NAC's function as an potent antioxidant, protecting human cells from damage in a wide variety of scenarios. NAC also has been shown to be an effective mercury chelating agent. Chelate (v.) is defined as "To remove a heavy metal, such as lead or mercury, from the bloodstream by means of a chelate."
