Did You Know?
It's not just your parent or your grandparent whose hearing may be slipping. A 25-year-old farmer can have the ears of a 50-year-old and not even know it!
Sound Advice: Protect Your Ears from Damaging Noise
Exposure to noise above 85 decibels (dB) can cause permanent hearing loss.
It can even result from a single nearby shotgun blast, dynamite blast or other very loud noise.
A "decibel" is the unit used to measure the loudness of sound. Decibel levels for each item shown in the graph may vary.
If you need to raise your voice to be heard an arm’s length away, the noise is probably loud enough to damage your hearing.
How Long Is Too Long?
The red bar below shows how long it takes for a particular sound level to become dangerous to the human ear. For example, a chain saw has a sound intensity of about 109 dB. Without proper hearing protection, running a chain saw for only 2 minutes can cause hearing loss!
It only takes...
If you know someone with hearing loss, you know that conversation can be frustrating for both of you.
A good hearing aid can help, because it amplifies the sound. However it does not make sound clearer the way glasses make your vision sharp.
Hearing aids do not correct hearing the way glasses correct vision.
What's That Ringing?
Have you ever driven an open cab tractor for several hours or gone to a loud concert, then heard a ringing in your ears for the next hour or two? How would you feel if that ringing never went away?
That's what happens to many people exposed to loud noise.
That ringing in the ears is called tinnitus, and while many people hear ringing, some hear hissing, roaring, whistling, chirping or clicking sounds. Tinnitus may show up before you even notice much hearing loss.
“My little girl doesn't understand why I can't hear what she is whispering in my ear. She says…‘Mommy hears me when I whisper’.” |
“I thought if I lost my hearing, it would be quiet. But that constant ringing keeps me awake at night and I can't hear my friends very well on my cell phone.” |
How Can I Protect My Hearing?
You don’t have to have the hearing of a 50 year old by the time you’re 25. It’s up to you to protect your hearing!
The best protectors are the ones you will wear all the time you are around loud noise.
Formable Earplugs |
Premolded Earplugs |
Canal Caps | Earmuffs |
There are hundreds of different styles of hearing protectors to choose from today. Everyone can find one that is convenient, easy to use, comfortable and fits his or her budget. “Hunter's” or “shooter's” muffs may work well for you. Hearing protectors are available on the internet and in local home improvement and farm stores.
Only trust your ears to products designed as hearing protectors. Cotton balls and other makeshift protectors can let noise pass right through.
“Getting used to wearing my earplugs was like getting used to my favorite boots even after getting a good fit, it still took a little time .”
