“Despite my proper use of hearing protection, I usually experience some temporary hearing changes after a couple of hours at the range. “
Seriously, this does not add up. You either are using cheap crap or your are wearing it wrong. Get better hearing protection or double up. Or both. In-ear foam or good muffs over top and you should not be having a problem. In-ear foam AND good muffs and you can’t possibly be getting hearing damage. Physics will not allow it.
FROM: Letter/Editor American Family Physician, March 15, 2001
to the editor: With regard to Dr. Rabino-witz’s fine article1 on noise-induced hearing loss, I wanted to add a telltale sign of hearing damage that occurs in shooters of shoulder firearms.
Shooters, as do most persons exposed to high sound levels, have a characteristic “notch” of greatest hearing loss at 4,000 or 6,000 Hz; however, shooters of shoulder arms have an asymmetric hearing loss with a greater deficit in the ear opposite the shoulder from which the gun is fired. Because most people are right-handed and fire from the right shoulder, the majority of shoulder firearm shooters show a deeper “4,000 Hz notch” in the left ear. This may seem counter intuitive, but the ipsilateral ear is somewhat protected by the angle of the head when shooting. The contralateral ear is more exposed to the sound of the muzzle blast.
Counseling hunters presents a considerable challenge. As Dr. Rabinowitz1 points out, the best way to prevent hearing damage is avoiding high-level sounds or using some barrier-like protection (plugs or muffs). Hunters are averse to wearing ear protection, claiming that they need to hear the movement of game they are hunting. I advise them to cover their ears when another person is shooting, to wear ear protection when the success of hunting depends more on vision than on hearing (watching for ducks to fly in rather than listening for the rustling of deer), not to fire unnecessarily and to wear ear protection during practice or sighting in.
I tell hunters that the choice is theirs: either practice hearing conservation or lose more hearing. I point out that communication difficulty will increase, social enjoyment and domestic tranquility will decrease, tinnitus may begin or worsen, and that a hearing aid may become necessary, although hearing aids are less successful with the notch patterns of noise-induced hearing loss than with most other patterns. I wonder if people would take the same risk with their vision?

in reply: I appreciate Dr. Peck’s comments regarding the problem of recreational firearm use and noise-induced hearing loss. Results from a recent study1 revealed an increased risk of marked high-frequency hearing loss among persons who had used recreational firearms. In addition to Dr. Peck’s practical suggestions for counseling hunters about the use of hearing protection, physicians discussing the prevention of hearing loss with hunters should be aware of the existence of devices offering “level–dependent hearing protection.”2 These devices can permit hearing of low-intensity sounds such as speech or animal movement, while attenuating louder sounds such as gunfire. These devices may be appropriate for use in certain hunting or shooting situations.2

Ear plugs and electronic muffs.

A Mesa Boogie amplifier turned up to 10 will do that too.
“Seriously, this does not add up.”
As I posted, some people are more susceptible to the damage. And doing the math: 165db - 34db (best case as far as I know) eguals above the damage decibels.
By the way. do not use the inside the ear phones that come with a lot of electronic equipment. Sound engineers tell me that the ear is designed to be used in its entirety not just the central channel. It will knock off the top your ability in the high range.
I have some hearing problem and I also wear my shooting earmuffs when I cut and trim the grass, use the chain saw and any tool that makes loud noises. I spent 35 years in mfg and you tell from my ears.
I have hearing loss in my left ear of 50%, and my right ear 25%. Concerts, hunting and uncle Sam’s boys club contributed to the condition.
Oh, and genetics too.
You will adapt and overcome.

My hearing loss is now pretty bad. If a single person is talking to me, I don’t have a problem. But if more than one person is talking to me at once, or someone is talking to me at the same time as the TV is playing, all I hear is noise.
I call it “Chinese restaurant syndrome.” I now refuse to go with my wife to dinners/parties at Chinese restaurants because it is always so noisy I can’t hear anything but noise and have to try to read lips all evening.
“Ear plugs and electronic muffs.”
You can’t add the decibel compression up. I’ve read credible sources that estimate a -22db device with a -30db device equals approximately -37db in hearing protection.
You take the highest protection level and add about 7db. It’s only an approximation.
I was reading your reply listening to the ringing in my ears. I fetched my aids from the bedroom and damn if the ringing was almost gone. VA didn’t tell me about that or I just forgot but they sure do help.
The over the ear earmuffs I use are electronic amplified earmuffs (Howard Leight Impact Sport) so I can hear range commands, I can carry on conversations in a normal voice with my spouse (who is similarly outfitted,) yet my loudest firearm, a Smith & Wesson J-Frame snubbie firing .38+P rounds, is very quiet. I have absolutely no ringing or 'temporary' hearing loss afterwards.
For hunting, I just wear the Howard Leight Impact Sport electronic muffs. With the volume all the way up, my hearing is *better* than normal, yet a shot from my .308 or .30-30 is attenuated. I would NOT want to do an all day range session this way, but the occasional shot while hunting is fine.
What I will never do is shoot without ear protection, either at the range or while hunting.
Good info. Thanks.

Glad I could help - thx for your service.
Huh?
Well I got severe hearing loss from working around Jet engines all my life.. It’s so bad on the high ends I can’t hear my Fire alarms when they go off.. I do Wear hearing aids however the loss is getting worst. Most times I can’t understand spoken words i have to read lips too..
Muffs AND ear plugs at indoor ranges
“...however the loss is getting worst.”
I was told that the loss won’t get worse if I am not exposed to the high-impact noises.
Please explain why it’s getting worse for you.
Thanks!

I seem to remember a service at Cabela’s, where they took a mold of your ear, and used it to make form fitting ear plugs. Seems these, plus electronic muffs over the ears, would make the range nice and quiet.
Get yourself a good set of electronic ear muffs and wear ear plugs in addition to the muffs. The muffs will amplify the sound of people’s voices enough for you to hear them even with the plugs in, and will shut down at a gunshot giving you a double layer of protection. I’ve been shooting rifle caliber big bore pistols for 30 years, and I have always doubled up on ear protection. It works.
