Study urges efforts to prevent noise-induced hearing loss

This report from Purdue University highlights research done there with the University of Rochester that shows noise-induced hearing loss has worse effects on hearing than hearing loss caused by age-related metabolic loss. Specifically, the researchers found that “noise trauma causes substantially greater changes in neural processing of complex sounds compared with age-related metabolic loss,” which the researchers think may explain why there are “large differences in speech perception commonly seen between people with the same clinically defined degree of hearing loss based on an audiogram.”

According to the CDC, noise-induced hearing loss is 100% preventable. In public health, prevention of disease is almost always better and cheaper than treatment of a disease or condition.  For hearing, natural hearing preserved into old age is much better and much cheaper than costly hearing aids.

So remember: if it sounds too loud, it IS too loud.  Avoid excessive noise exposure and use hearing protection now, or need hearing aids later.

Fireworks can cause hearing problems

This press release from Purdue University discusses the fact that noise from fireworks can cause hearing problems.

There are several errors in the press release. Namely, the 85 decibel noise level cited is an occupational noise exposure standard that isn’t safe for the public nor is it meant to be a standard for the general public. But the main thrust of the piece is a good, general warning that loud noise is bad for the ears.

And the advice offered by Anne Sommer, an audiology clinical instructor at Purdue, that double hearing protection–foam ear plugs and ear muffs–should be used when setting off personal fireworks is sound.

I would only add that if double protection is needed for an unnecessary task, the more prudent option is to avoid exposure. After all, one really shouldn’t set off personal fireworks unless one is willing to accept the loss of an eye or a finger. Fireworks, which are banned in Los Angeles, are inherently dangerous and are really best left to the pros.
