Too Loud! For Too Long!

Loud noises damage hearing

Hearing loss is costly.

The cost for the first year of hearing loss treatment in older adults is projected to increase more than 500% from $8 billion in 2002 to an estimated $51 billion in 2030.

Hearing loss from loud noise can be prevented.

About 70% of people exposed to loud noise never or seldom wear hearing protection.

How hearing loss occurs.

Common noises can be loud.

  • 70dB (decibels) Washing machine
  • 80dB Traffic noise inside a car
  • 90dB Leaf blower  2 hours can cause damage
  • 100dB Sporting Event  14 minutes can cause damage
  • 110dB Rock concert  2 minutes can cause damage
  • 120dB Siren  1 minute can cause damage
  • 85dB is the approximate point at which extended exposure can cause hearing damage.

How noise causes permanent hearing damage.

Graphic showing silhouette of a man using a blower on a yard. The sound of the blower is shown penetrating a big ear, going to the inner ear to the right of the man, and causing hear loss. Images of  healthy hair cells and damaged hair cells are shown to the right of the big ear.

Sound vibrates the eardrum and tiny bones in the ear which in turn vibrate the hair cells in the inner ear. Exposure to loud noises over time can permanently damage the hair cells, causing hearing loss.
