New evidence that noise exposure directly damages the brain

As if we didn’t already know noise exposure is not good for us, a recent Italian study has found that noise directly damages the brains of rats. That is, noise doesn’t simply affect the tiny structures of the inner ear, which we already know, but also damages the brain. The research reveals that noise results in changes to DNA, neurotransmission, and structural changes to the brain itself.

While this study was done on rats using high noise levels, we would likely see a similar effect on humans. At the very least we should try to limit noise exposure as much as possible. This means avoiding loud noise where possible and using hearing protection when you are exposed, whether it is for work or play.
