Hearing Damage: Technology

Music used to bind us together, whether we liked classical music at concerts, or whether we enjoyed the sort of light pop played on the radio. It still does so to a much greater extent than anything else in our divided society. But the phenomenon of plugging in earbuds removes the social element from musical enjoyment.

There is something bleak about this. Societies are happy when the greater number have mastered social skills, and this must depend upon people learning to appreciate one another.

How can this be done if we are all plugged in to our separate earbuds, shattering what was left of our hearing, and completely insensitive to the nuisance we are creating for the person sitting at our side?

By the time they are 35, this generation will have experienced serious hearing loss. Of that, medical research is in no doubt whatsoever.

Earbuds - the tiny speakers that fit inside your ears - are universally more popular with young listeners than the less stylish headphones, but have been proven by medical research to damage hearing irreparably, and to do so fast.

Exposing your ear drums to badly mixed rock music at 110 or 120 decibels is the equivalent of standing near a jet aircraft.

And will people try to sue Sony or Apple for hearing damage the way many have pursued tobacco companies for the damage their products cause?

Who is forcing us to put those micro earpieces in and blast our hearing away?

How do I know if noise could be hurting my ears?

You may be exposed, at work or through hobbies, to noise that hurts your hearing. If you have to shout when you talk to a coworker who is standing next to you, the noise level at your workplace may be hurting your ears.

Both the loudness of sound (called the intensity) and the amount of time you hear the noise are important. Sound is measured in decibels. Eight hours of hearing noise at 85 decibels could hurt your hearing. At higher sound levels, you could lose hearing in even less time.

Noise is measured in units called decibels, on a scale from zero to 140. The higher the number in decibels, the louder the noise. The louder the noise, the greater the risk of hearing loss. Hearing loss can occur with regular exposure to noise levels of 110 decibels or more for periods longer than one minute. No more than 15 minutes of unprotected exposure to 100 decibels is recommended. Long-term exposure to 80-85 decibels or over can cause hearing loss.

Here is a list of common noises and their decibel levels:

  • Aircraft at take-off (180)
  • Fireworks (140)
  • Snowmobile (120)
  • Chain saw (110)
  • Amplified music (110)
  • Lawn mower (90)
  • Noisy office (90)
  • Vacuum cleaner (80)
  • City traffic (80)
  • Normal conversation (60)
  • Refrigerator humming (40)
  • Whisper (20)
  • Leaves rustling (10)
  • Calm breathing (10)

Noise levels of 130 decibels or over will be painful and is very likely to cause immediate hearing damage.
