Had custom molded plugs made. Block everything. Some of the best money I’ve spent on the shooting sports, and I’ve spent plenty.

Yeah, I can block out all I want when I'm at the range. I wear plugs and muffs and it works ok. My magnums these days are all loaded down to midrange levels. Some are at the bottom of the "magnum" velocity. It's a private range and I'm usually the only one there. No range commands I need to hear.

But I want to start hunting again and I need to be able to hear ambient noise. Deer walking through leaves, etc.

Assuming the legend is accurate, 140dB and above instant/short duration noise at the ears produces damage, that's my concern.

A 30-06 rifle with 24 inch barrel produces 158.5dB of noise. My Howard Leight Impact Bolt electronic muffs has a NRR of 22. That means I'm exposed to 136.5dB which is technically in the safe range.

Unless, there is some other correction in formula for short duration noise. Hence, this thread.
