I typically double up my hearing protection at the range (30 NRR muffs + earplugs = 35 NRR). If I'm doing my math correctly, that should come out to a db reduction of (35 - 7)÷2 = 14. With handguns at indoor ranges being ~160db, how the frack do I not have hearing loss when I'm exposed to ~146db sound every time I go to the shooting range?

OSHA standards top out at 115db, so I'm not certain what to use as a benchmark.

IIRC according to Silencershop 140db is ok for no earplugs. Not sure what earplugs you are using that are only 5 NRR most all are around 30 NRR.

When doubling up on hearing protection (earmuffs + earplugs), you take the higher number (my 30 NRR muffs) and add 5 to calculate the combined NRR.

Eh that sounds like bullshit, pun intended. Why 5? It depends on both the earplugs and muffs.

Just pay for the tax stamp and get a suppressor. 140 db is pretty safe, you can get below that with good suppressors, and with earpro and a suppressor you are golden.

Not mention shooting outside. I went to an indoor range twice in my life and both times sucked, and not just because of how loud it was.

Form 4 suppressors are going to E-file soon too. So they are saying it's going to take 6-8 weeks instead of 9-12 months.
