Have you heard? Noise-induced hearing loss is preventable

By Jeffrey Hutchins, Regional Loss Prevention Manager

Hearing loss is something that can affect any of us not only on the job, but in every aspect of our lives.

However, because noise-induced hearing loss (NIHL) happens gradually over time, many of us don’t give it the attention it deserves.

That’s why the National Institute on Deafness and Other Communication Disorders (NIDCD) designates every October as National Protect Your Hearing Month. The NIDCD urges you to learn simple ways to protect yourself, your family, and co-workers from NIHL. The following simple solutions from the NIDCD can go a long way toward protecting your hearing.

Turn down the volume

Set maximum volume limits on electronics and keep the volume low on music devices and TVs. Sounds at or above 85 decibels (comparable to heavy city traffic) put you at risk for NIHL, especially if they last a long time. These days, earbuds are a common concern.

“There’s nothing wrong with earbuds that are producing sounds at a low, nontoxic level. But earbuds are bad when you turn them up too loud,” says Dr. James Battey, former director of the NIDCD. “My rule of thumb is, if an individual is standing at arm’s length from you and they can hear your earbuds…that noise is probably over 85 decibels and if delivered for a long enough time will cause noise-induced hearing loss.”

Move away from the noise

To reduce sound intensity and the impact of noise on your ears, increase the distance between you and the noise. Think of this simple step when you are near fireworks, concert speakers, or in a loud restaurant.

Wear hearing protection

Sometimes you can’t easily escape the sound, whether you’re at a movie theater, a concert, a sporting event, or a noisy work environment. Earplugs or protective earmuffs can help. There is a single number required by law on each hearing protector called the noise reduction rating. The NRR for hearing protectors can range from 17-33. The higher the NRR number, the more effective the protection. Be a good hearing health role model by wearing them yourself. If you don’t have hearing protectors, cover your ears with your hands.

In the workplace, think about the types of equipment or jobs that can cause hearing loss, such as:

  • Circular saws
  • Chain saws
  • Firing guns
  • Air-powered ejection equipment
  • Air-operated equipment without mufflers
  • Metal stamping
  • Machining operations

Once you’ve identified the potential sources of loud noises, be sure to take the proper steps to protect yourself and your co-workers from danger. The good news is NIHL is the only type of hearing loss that is completely preventable. If you understand the hazards of noise and how to practice good hearing health, you can protect your hearing for life.

BWC can help

Our industrial hygienists can help you identify NIHL hazards in your workplace with consultations. Our Hearing Conservation Program webinar can be viewed on-demand. The BWC Library also has plenty of resources, including videos, about noise and hearing conservation.

Daylight Saving Time Ends Sunday, Nov. 7.

It’s almost time for the end of Daylight Saving Time. At 2 a.m. on Sunday, Nov. 7, we return to Eastern Standard Time. We gain an extra hour as we “fall back,” but despite this advantage, this biannual ritual of changing our clocks can mess with our internal clock.

When we turn the clocks back one hour this weekend, it is as if we crossed one time zone westward. For some, it may take up to a week to become accustomed to waking and sleeping one hour later. You will notice it will be lighter for your commute on Monday morning following the end of Daylight Saving Time. Conversely, it will get darker an hour earlier in the evening, so there may be less daylight for your evening commute.

Research has shown that there are more sleep disruptions in the week following the changing of the clocks. Nighttime restlessness tends to increase, resulting in poor sleep quality.. Morning “larks” are more bothered by the autumn change, while night “owls” fare worse with the spring change.

Whether you’re a “lark” or “owl”, you should expect a few restless nights following the end of Daylight Saving Time and be prepared to make some adjustments. The upcoming “fall back” will give most of us a much-needed chance to catch up on sleep, so take full advantage of that extra hour of zzz’s.

While more light may make your morning commute easier, the opposite – less light – can occur for your evening commute. Because vision may be poorer, give yourself extra following distance on the road. Be alert for cyclists or pedestrians who may be harder to see in dimmer light. Driving a little slower will give you more time to react to unexpected events.

As your body slowly adjusts to the new hours of waking and sleeping, you should be able to fall asleep more easily and stay asleep. You’ll become accustomed to the new lighting levels for the morning and evening drives. That is, until next spring, when we again change our clocks and start the readjustment period all over again!
