Like Being Able to Hear? Protect Your Ears When Shooting!
Shooting without hearing protection damages hearing by creating increased air pressure on the ear drums. Excessive noise causes the drums and attached bones in the middle ear to vibrate violently. This vibration is transferred to the liquid-filled inner ear, and when the sound level is over 85 decibels, inner ear fluid pressure is sufficiently high to initiate damage to small inner-ear hair cells that convert vibrations into the electrical impulses that register as sound in the brain. As more of these cells suffer permanent damage and eventually die, your ability to hear is reduced. Once the cells are gone, they’re gone for good.

Most centerfire calibers produce noise levels between 140 and 190 decibels. When several guns are fired simultaneously on an indoor shooting range, the noise level can rise far above 190 decibels. Worse yet, the decibel scale is logarithmic, so 190 decibels is actually many times greater than 85 decibels. Because of this, a single gunshot often produces temporary damage by stunning the cells in unprotected ears, and repeated exposure without hearing protection often results in permanent hearing loss. Of course, sound isn’t only transmitted by the ear drum. The bones of the skull also transmit pressure waves from a gunshot, and this further increases pressure on the inner ear. Now put 20 service members on a covered range and have them all shoot at once, and you can imagine the abuse my ears took on that sunny afternoon in Alabama so many years ago.
Different Types Of Electronic Hearing Protection
Today, there are two basic types of electronic hearing protection offered to the general public: passive protectors like foam ear plugs and muffs, and active protectors that combine either plugs or muffs with electronic circuitry. The electronic protectors usually amplify soft ambient sounds by as much as 30 decibels, and they also have dynamic range compression circuitry that attenuates loud noises. The attenuation circuits quickly block sound that is above a preset threshold, usually somewhere between 70 and 95 decibels. Almost all hearing protectors have a noise reduction rating, or NRR, of at least 19 decibels, and some reduce loud noises by up to 33 decibels.
Foam earplugs and muffs are relatively inexpensive and, when worn together, can be very effective. Unfortunately, they can be so effective that they block sounds you want to hear like range commands and the noise made by game animals as they move through the forest. They also have other drawbacks. Unless they are custom-molded silicone or acrylic products like those from WildEar, earplugs can work their way out of the ear canal and become ineffective. And ear muffs can be so bulky that it’s difficult to shoulder some types of long guns. However, passive ear protectors can be effective in reducing noise when used properly. Passive earmuffs and plugs have NRRs of up to 33, and the WildEar passive molded plugs have an NRR of 26.
There’s a wide variety of electronic hearing protection devices on the market. Prices vary according to the number of features, the level of noise suppression, and the length of the warranty. So here are some of the latest electronic hearing protectors to help you out.
AXIL TRAKR BLU Electronic Earmuffs
The AXIL TRAKR BLU electronic earmuffs provide a more slim and compact option for electronic hearing protection. They also allow hearing amplification of up to 40 decibels. The earmuffs possess 27-decibel SNR hearing protection and 5.0 Bluetooth support for audio and hands-free communication. The earmuffs protect your ears by sound-activated compression in .02 seconds. AXIL’s Autoblocker Technology compresses all sounds over 82 decibels. The TRAKR BLU earmuffs also reduce wind noise for better hearing capabilities on blustery range days. Lastly, they’re sweat- and water-resistant to keep you protected no matter the temperature or weather.
Champion Electronic Earmuffs
This highly affordable earmuff-style protector has a noise reduction rating of 25 decibels, and it also amplifies low-level sounds. Champion’s electronic hearing protector is also collapsible for easy storage when you’re not on the firing line.
