This is what happened to me. Loud noises—concerts, power tools, gunfire, heavy machinery, even loud headphones—damage the hair cells in your cochlea. Those cells don’t regenerate. Once they’re damaged, they’re damaged forever.

The science: Studies show that chronic noise exposure is the leading cause of tinnitus, accounting for up to 80% of cases. The damage is cumulative. One loud concert might not do permanent damage on its own. But years of lawn mowing, power tools, loud music, and traffic noise add up.
