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.

I was using my new Walker noise cancelling muffs this weekend. They did OK but it's not what I was expecting. Regular muffs seem better, at least after one trial run. I just got sick of having to constantly say "WHAT?" to range buddies when they were talking to me and I had normal muffs on.

Pretty sure I could perceive the delay in the noise cancellation. I think they should have insulated the shell better.

Edit: but I was also wearing a beanie. The seal around the ear wasn't perfect. Eh.
