Scientists found when they administered nicotinamide riboside to mice, the mice with high level of sirtuin 3 were resistant to noise induced hearing loss.

Our ears are very sensitive and can be damaged when exposed to very loud noise, experience head/ear trauma and from certain diseases. For example intense noise can lead to hearing loss caused by the degeneration of hair cells in our ear.

Scientists at Weill Cornell Medical College investigated whether it was possible to protect these cells from harm and thus reduced the likelihood of noise induced hearing loss.

Their experiments on mice showed that under certain conditions, they were able to protect the nerve ending when the mice were exposed to loud noise.

The researchers believe this new knowledge could open a new avenue to treat age related hearing loss.
