• • Listen to sounds in a way that is enjoyable, but will not harm you
  • Hearing loss can occur from exposure for thirty second, or from long-term exposure.
  • between 10% and 20% of teenagers have hearing loss
  • Sound is measured in decibels (dB)
  • Pain usually begins around 125dB, a live concert easily hits from 100-150
  • 1 of 12 35-year-olds have hearing loss, and over a third of that is due to loud sounds
  • Once your hearing is damaged, it cannot be healed. You hear through hairs deep in your ear, and they develop before you are born, and you never get more
