October is “National Protect Your Hearing Month.”Posted on by
October is “National Protect Your Hearing Month,” a time to raise awareness about what you need to do to protect your hearing.
Did You Know?
Repeated exposure to loud noise over the years can damage your hearing—long after exposure has stopped.
This is just one of the many informative facts available on CDC’s National Center for Environmental Health’s new hearing loss website: https://www.cdc.gov/nceh/hearing_loss/default.html.
Think you’re well aware of how to protect yourself? When it comes to hearing loss, we can all think of the usual suspects: listening to fireworks, attending sporting events, and loud concerts.
However, you may be surprised at what you don’t know. For example, everyday activities such as using power tools, mowing the lawn, or attending a fitness class with loud music can damage hearing.
The site features detailed information on the following topics: “What Noises Cause Hearing Loss?” “How Does Loud Noise Cause Hearing Loss?” “How Do I Know if I Have Hearing Loss Caused by Loud Noise?” “How Do I Prevent Hearing Loss from Loud Noise?” and “What If I Already Have Hearing Loss?”
Browse the pages to discover critical information you’re likely unaware of.
Is the noise too loud? If you need to shout to make yourself heard, yes.
After a very loud event, such as a concert or football game, normal hearing usually returns within a few hours to a few days—however, repeated exposure to loud noises will eventually damage the inner ear permanently.
Ways to protect your hearing include turning the volume down, of course, and also taking periodic breaks from the noise and using hearing protection.
Signs that you may have hearing loss include difficulty hearing high-pitched sounds (e.g., doorbell, telephone, alarm clock) and difficulty understanding conversations in a noisy place.
By the Numbers
“Sound is measured in decibels (dB). A whisper is about 30 dB, normal conversation is about 60 dB, and a motorcycle engine is about 95 dB. Noise above 85 dB over a prolonged period of time may start to damage your hearing. Loud noise above 120 dB can cause immediate harm.”
Hearing loss is the third most common chronic health condition in the United States. Almost twice as many people report hearing loss as report diabetes or cancer. In the United States, about 40 million adults aged 20–69 years have noise-induced hearing loss, and about 1 in 4 adults who report “excellent to good” hearing already have hearing damage.
Think that hearing damage is usually workplace-related? Actually, activities away from work can damage hearing just as much a noisy job. Over half of all adults with hearing damage do not have noisy jobs.
“By the time you notice hearing loss, many hair cells have been destroyed and cannot be repaired.”
The average person is born with about 16,000 hair cells within their inner ear. These cells allow your brain to detect sounds. By the time changes in your hearing can be measured by a hearing test, up to 30% to 50% of hair cells can be damaged or destroyed.
There is no treatment for hearing loss! Damaged inner ear cells do not grow back. Protect your hearing, and if you already have hearing loss, take steps to keep it from getting worse.
