Like what's the point of NRR (noise reduction ratings) on earplugs? Imagine your average gun going off at 165 dB. The NRR calculation states that the rating should be subtracted by 7 and then divided by 2. Let's say you have some earplugs with the maximum NRR of 33. That would mean you're exposed to 165 - ((33-7)/2) = 152 dB which would still blow your eardrums to Saigon. So, can someone explain me what the point or rather the reality is of the whole decibel reduction and if it's better to use earmuffs, earplugs or doubling up? Also have you dealt with hearing loss/tinnitus from shooting firearms even when using earpro? Thanks!

After a certain point, sound will just travel through flesh around your ears, even if you pack two pillows worth of foam into your ears.

Double up with plugs and high rated muffs and you'll be fine. I spent like a week researching this shit and it's extremely complicated but that's the take away.
