Hearing loss sneaks up on you. Every time you ring your ears you are accruing permanent damage. I was generally pretty good about hearing protection with range time, but spent a lot of time hunting birds and big game without them. I would go through 200-300 rounds of 12 ga per year in the field without ear pro. That all started to catch up with me in my mid-40s, when consistent tinnitus set in. Now I pay a lot of attention to the noise reduction ratings on ear pro. Most won’t reduce a gunshot from a centerfire rifle to hearing safe levels. I started noticing this due to increased tinnitus after range time while wearing ear pro. Nowadays I double up on the range.
Do the math, if your ear pro has a NRR of 22 and you are shooting a 308 at 165 dB. That puts you at 143 dB. That’s over the suggested limit for short duration exposure. Now what dB level does a braked 300 win mag put out? Even if you double up on the big boomers, you are still getting enough sound waves through your skull to damage your hearing.
At 53, I’m buying my first suppressor so that I can get away with one set of electronic ear plugs while hunting. My wife told me to get off my ass and buy one because of concern for my hearing. She said she doesn’t want to have to yell at me or be yelled at by an old deaf man after retirement. Honestly, I’m not sure it’s not going to happen anyway at this point. I wish I was less stupid when I was younger.
