- Is it True That Loud Noise May Cause Hearing Loss?
-
-
- ------------------------------------------------------------------------------
-
- QUESTION: We are concerned with the problems of hearing loss that seem to
- afflict some of us. In listening to all the "war stories" it would seem that
- loud noise may have been a cause for some of the damage. Can you please tell
- me if this is true?
-
- ------------------------------------------------------------------------------
-
- ANSWER: Yes, it can. Excessive noise is the leading preventable cause of
- hearing loss in this country. Many veterans of past wars, particularly those
- who were in close contact with heavy artillery, are well aware of this fact.
- Excessive noise can either be continuous, such as jackhammers or
- industrial machinery, or acute, such as a gunshot or explosion. Continuous
- loud noise causes degeneration in the tiny hair cells of the cochlea of the
- ear. These cells pick up sound vibrations and cannot be replaced or repaired.
- The longer you're exposed to excessive noise, the more hair cells are
- destroyed, and the more hearing loss. This damage usually results in hearing
- impairment, and only rarely in profound deafness.
- Acute loud noises can rupture your tympanic membrane (the ear drum) and
- other membranes in the inner ear. A ruptured ear drum can heal and hearing
- can be restored, but inner ear damage cannot.
- In the early stages of noise-induced hearing loss, you may experience
- ringing in the ears, sound muffling, ear discomfort, or a temporary hearing
- impairment for a few hours after experiencing the noise.
- The Department of Labor says that more than 5 million American workers
- are subjected to hazardous noise levels. A good rule of thumb is that if you
- must shout to be heard over the background noise at work, your hearing is in
- danger. Use hearing protection such as ear plugs or special ear muffs. Even
- rock musicians are wearing ear protection now during concerts. I wish more of
- our young people would get the hint, and be more careful about the levels of
- sound they use when listening to music.
