The guinea pig's natural diet is grass; their molars are particularly suited for grinding plant matter and grow continuously throughout their life.[93] Most mammals that graze are large and have a long digestive tract.
Preventing noise-induced hearing loss (NIHL) by antioxidants is based on the hypothesis that generation of reactive oxygen species is one of the causes of NIHL. -Tocopherol is a naturally occurring antioxidant with no noticeable side effects.

The goals of this study were to: 1) determine the contributions of both implantation surgery and EAS to hearing loss in a normal-hearing guinea pig Hybrid CI model; 2) determine which cochlear structural changes are associated with hearing loss after surgery and EAS. Guinea pigs have been used in diverse studies to better understand acquired hearing loss induced by noise and ototoxic drugs. The guinea pig has its best hearing at slightly higher frequencies relative to humans, but its hearing is more similar to humans than the rat or mouse. Based on the cellular ubiquity and antioxidant properties of vitamin C, we hypothesized that animals fed a vitamin C-decient diet would develop more PTS than control animals on a normal diet, whereas animals fed a vitamin C-enriched diet would develop less PTS than controls.
