teen health ears music decibels

  • The amount of energy in the noise and the damage it can do to your hearing increases very rapidly as it gets louder. In fact, noise energy doubles for every 3 decibels (3dB) increase in the loudness of the sound - and 3dB is such a small increase in loudness that you probably wouldn't even notice it.
  • What sort of noise causes the harm? For young people in particular, the most dangerous noise is amplified music, for example in gigs and clubs. Headphones, car stereos and mobile phones are also having a bad effect on the hearing of young people.
  • Research shows that 25% of people listen to headphones at a level that will cause hearing damage. Follow the 60/60 rule - don't have your player above 60% of the maximum volume, and don't listen to it for more than 60 minutes at a time.

  • One study suggests that listening to headphones at 80% for 90 minutes a day can lead to hearing loss. The authors say that this can take years for the damage to show up, so young people might not notice a loss of hearing until they are in their late 20s. At 100% for only five minutes you could do damage.

  • In night clubs - where much of the damage is done - do not stay long, don't go too often and keep well away from the loudspeakers - or go somewhere else where the music is not so loud.
