I've lost a good bit of my hearing over the years and have been researching the causes for it (other than old age!). This is what I've collected from other forums and the internet. If you have information to add to this, please do so.
Noise levels of different firearms and other sources
Facts on noise levels: 1. Decibels measure sound pressure and are logarithmic. That means that only a 3db increase almost doubles sound pressure, a 6db increase quadruples sound pressure, etc. 2. Gradual hearing loss may occur after prolonged exposure to 90 decibels or above. 3. Exposure to 100 decibels for more than 15 minutes can cause hearing loss. 4. Exposure to 110 decibels for more than a minute can cause permanent hearing loss. 5. At 140 dBA noise causes immediate injury to almost any unprotected ear. 6. There is also the more extreme ‘acoustic trauma’, which is an immediate loss of hearing after a sudden, exceptionally loud noise such as an explosion.
Comparative noise levels and length of time for damage to occur: Jet engine taking off 140 dB Instant damage Thunder/Ambulance siren 119 dB 3 minutes Hammer drill 113 dB 15 minutes Chain saw/Earphones/Concert 110 dB 30 minutes Bull Dozer 105 dB 1 hour Tractor/Power tools 96 dB 4 hours Hairdryer/lawnmower 90 dB 8 hours
Noise levels of firearms: .22 caliber rifle 130dB .223, 55GR. Commercial load 18" barrel 155.5dB .243 in 22" barrel 155.9dB .30-30 in 20" barrel 156.0dB. 7mm Magnum in 20" barrel 157.5dB. .308 in 24" barrel 156.2dB. .30-06 in 24" barrel 158.5dB. In 18" barrel 163.2dB. .375 18" barrel with muzzle brake 170 dB. .410 Bore 28" barrel 150dB. 26" barrel 150.25dB. 18" barrel 156.30dB. 20 Gauge 28" barrel 152.50dB. 22" barrel 154.75dB. 12 Gauge 28" barrel 151.50dB. 26" barrel 156.10dB. 18" barrel 161.50dB. .25 ACP 155.0 dB. .32 LONG 152.4 dB. .32 ACP 153.5 dB. .380 157.7 dB. 9mm 159.8 dB. .38 S&W 153.5 dB. .38 Spl 156.3 dB. .357 Magnum 164.3 dB. .41 Magnum 163.2 dB. .44 Spl 155.9 dB. .45 ACP 157.0 dB. .45 COLT 154.7 dB.
Properly fitted earplugs or muffs reduce noise 15 to 30 dB. The better earplugs and muffs are approximately equal in sound reductions, although earplugs are better for low frequency noise and earmuffs for high frequency noise.
Using muffs and plugs together: Take the higher of the two and add 5 dB. 30 plug with 20 muff gives an effective NRR of 35.
If you are shooting by yourself, with plugs and muffs on, you get to shoot up to a thousand rounds without damage (louder ammo/gun and the allowable drops by a factor of 5). Shoot with other people and you have to add all the rounds shot cumulatively (10 people shoot 100 rounds and everybody's done for the day; toss a handcannon or 30 cal rifle in and you're back down to 200 rounds cumulative). If you shoot on an indoor range then all the rounds fired while you are on the range go into your total. So you can see that it doesn't take very long on a range to have a thousand rounds popped off around you.
Don't forget about bone conduction of concusive sound waves. The mastoid bone will transmit the sound vibrations directly to your inner ear where the cochlea and the hearing nerves reside. Constant exposure to these kinds of concusive sound waves, ie: 50 BMG, industrial heavy machinery, will result in the degradation of your hearing quality. Even with ear muffs, bone conduction is a big factor in hearing.

Yet the federal government makes us jump through hoops to get suppressors.

Yep! Jump through hoops, takes forever, and shakes you down for some coin for your stamp. THEN you can buy an expensive suppressor (the cost to build them can't be more than 50-60 bucks) and you can finally get on with it. Maddening.

Laser to re attach retinal detachment is the worst pain I have ever experienced!! Like having an ice pic driven through your eye and out the back of your head! I have had it done 4 times. Told DR to strap me in the chair!

Interesting to see where the 41 rated, made the mistake of shooting one without hearing protection and it was partially inside the vehicle. I knew the moment I pulled the trigger I'd done damage. What led to this was a coyotes crossing the road and I was in my company car, instead of getting out I rolled down the passenger window and shot it from the driver side.
One I don't see on the list is the 30 Carbine, that's another one that will ring your bell.
Yes! A Weatherby does kill them deader.

Yup. It's a noisemaker out of a Ruger Blackhawk for sure.

We used to site guns in at my grandpa's farm without ear plugs. Now I wont start a tractor, lawn mower, weed eater, chain saw etc. without ear plugs. I also quit driving hwy trips with the windows down, just too much noise.

I have tinnitus bad just a perpetual ringing in my ears. Can only hear it when it's quiet though. I can't really sleep at night without the air conditioning on or some kind of ambient noise. Otherwise I just sit and have this buzzing noise in my ears drives me bananas. I won't shoot anything that isn't suppressed or I have really good ear pro on. I did it a lot growing up and as a young adult. Paying for it now.

Most wait until they have some level of hearing loss if they ever learn at all.

I am only 32 but unfortunately already have some amount of hearing loss. One of the reasons I don't like bars or concerts anymore, with the background noise I just cant understand people well.
On the other hand my wife has perfect hearing and in the woods etc. I hear all kinds of stuff she never hears lol.

I have a bit of tinnitus, I believe, but it just doesn't bother me. What DOES bother me is difficulty in hearing and understanding speech in noisy places, like redchevy. I usually end up feeling left out of conversations in those circumstances, and I tend to try and avoid such gatherings.
I never worked on drilling rigs, but I know a few who have. I've been told that the unchanging sounds are loud, but sleep is possible, and that's not too hard to imagine having slept plenty on propeller-driven aircraft. I've also been told that you get so used to the sound of the rig that the smallest change in the sound is very noticeable. My ex-brother-in-law would tell me he could hear a pin drop. Exaggeration, maybe...but I get the idea.
When my grandfather was alive I watched hundreds of football games with him. One afternoon during a game my grandmother walked into the room, stood in front of the TV, and yammered at him about some BS for about five minutes. He had learned to tune her out after 50 years...and she ended up storming out of the room after losing her temper and calling him a deaf dirty old man, or some such, and that he had better get a hearing aid. A few moments later I asked him if he had ever considered getting a hearing aid. He said "why in HELL would I want a g****m hearing aid???" as he stubbed out his cigarette with great force. I fully understood the point.

A couple years ago, I started wearing ear plugs for nearly everything. Didn't realize it was such a major issue til I started hearing older folks talk about all the stuff they didn't use protection for and how they can't hear anymore.
I'm like redchevy - 33 years old and already have trouble hearing in places with background noise. It annoys my wife. But hopefully this will be the end of it since I use plugs all the time now.

When shooting unsuppressed or around others, I always double up: Peltor-Tep100 and ProMag Tac Gold. Not the most comfortable setup but gives me the highest NRR while still retaining good amplification (ProMags don’t have great volume). When shooting suppressed, I use my Peltor 500 with the gel inserts. Lower NRR but much more comfortable. No desire to lose the hearing I have left.

I am almost totally deaf in my left ear and quite a bit of loss in my right ear, however mine is due to work. Did a lot of testing and repair on very high db and frequency military items. It destroyed my hearing in the left ear. it was the ear that was closest to source. I wear hearing aids in both ears but very little help in the left. Wife and I were sitting in 4x6 stand hog hunting when aid in my left ear beeped twice to tell me battery was low. My wife turned to me and asked "did you hear 2 shots?" I told her it was not shots, it was aid beeping for a new battery.
Long story short USE EAR PROTECTION WHEN IN ALL NOISEY SITUATIONS!!!!!
