Noise Induced Hearing Loss (NIHL)

September 21, 2016 by Raji Parangad

NIHL can be caused by a one-time exposure to an intense “impulse” sound, such as an explosion, or by continuous exposure to loud sounds over an extended period of time, such as noise generated in a woodworking shop.Recreational activities that can put you at risk for NIHL include target shooting and hunting, snowmobile riding, listening to MP3 players at high volume through earbuds or headphones, playing in a band, and attending loud concerts. Harmful noises at home may come from sources including lawnmowers, leaf blowers, and woodworking tools.

Sound is measured in units called decibels. Sounds of less than 75 decibels, even after long exposure, are unlikely to cause hearing loss. However, long or repeated exposure to sounds at or above 85 decibels can cause hearing loss. The louder the sound, the shorter the amount of time it takes for NIHL to happen.

Here are the average decibel ratings of some familiar sounds:

    • The humming of a refrigerator
      45 decibels
    • Normal conversation
      60 decibels
    • Noise from heavy city traffic
      85 decibels
    • Motorcyles
      95 decibels
    • An MP3 player at maximum volume
      105 decibels
    • Sirens
      120 decibels
    • Firecrackers and firearms
      150 decibels

Your distance from the source of the sound and the length of time you are exposed to the sound are also important factors in protecting your hearing. A good rule of thumb is to avoid noises that are too loud, too close, or last too long.

If you are exposed to noise recreational or work related get your hearing measured…… But make sure you have at lease 24 hours of no exposure to noise before getting your hearing assessed.  Please call ‘ My Audiologist” on 07 3446 5845 for a  comprehensive hearing assessment….  And yes we do Workcover claims and assessment….
