What is Noise-Induced Hearing Loss?

We live in a noisy world and dangerously loud sounds are all around us from many sources.  Loud and repeated sound exposure can permanently damage your child’s hearing and cause hearing loss and/or tinnitus (aka ringing in the ears). The risk of hearing damage increases with louder sounds, higher volume settings, and longer listening times and it is also cumulative (increases over time). Loud and possibly dangerous sounds may include:

  • Personal music players
  • Power tools and farm machinery
  • Music concerts
  • Sporting events
  • Video games
  • Shooting sports

Sign and Symptoms of Noise-Induced Hearing Loss

Since noise-induced hearing loss can occur over time, your child may or may not be experiencing immediate symptoms. Possible symptoms of noise-induced hearing loss include:

  • Tinnitus (ringing in the ears)
  • Temporary muffled hearing after a loud noise exposure
  • Pain or fullness feeling in the ears after a loud noise exposure
  • Difficulty understanding speech
  • Heightened sensitivity to loud sounds

What Can You Do to Prevent Noise-Induced Hearing Loss?

Hearing damage from noisy work and leisure activities is often thought of as an adult problem, but noise-induced hearing loss affects an estimated one in six children by the end of their teenage years. Since this type of injury is entirely preventable, it is important for parents and caregivers to know how to protect their child’s hearing.

Parents and caregivers can model healthy hearing habits for children:

  • Try to choose the lowest comfortable listening level in every situation
  • Move away from loud or bothersome sound sources
  • When engaging in a loud activity, have children wear age-appropriate hearing protection. Earmuffs that tailor to children's smaller heads are available in kid-friendly colors and graphics. For infants and small children who may not tolerate traditional earmuffs, adjustable elastic head-band style earmuffs may work well.
  • Set time limits for potentially loud activities. Since loud sounds damages hearing over time, reducing the amount of time spent listening to a loud sound will reduce the risk of developing hearing damage.

When selecting headphones for a child, note that all personal listening devices can produce dangerously loud sound levels but certain types of earphones and headphones are designed to support healthier listening habits:

  • Noise-isolating earphones. Earbud style (noise-isolating) earphones allows the listener to enjoy music listening at lower volumes when in the presence of loud background noise (i.e., in a subway, train, or airport). However, it is important to maintain environmental awareness for safety cues.
  • Noise-cancelling headphones. Active electronic noise-cancelling headphones may make listening more comfortable when in noisy places, but these products do not assure a safe overall listening level.
  • Output-limiting earphones. Earphones that limit the maximum sound level are commercially available and often marketed to parents as “safe children’s earphones”. Most products have been shown to function as indicated, however parental supervision is required to ensure proper use and listening habits.
