Worst suppressor you've owned

Went and checked if we had data on the arc 30 since we have metered at Bryans place in the past. It metered 141.2 at the left ear on a 16inch AR with 62 gr ammo. It did meter sub 140 at the muzzle but probably not a good place to put your ear when shooting.
yea id say you wouldnt want it there lol. its possible it was the tone, i am much more sensitive to high frequencies and tones than i am low ones. This was shooting dirty steel case wolf 55gr.
 
Sonic crack
what is the DB rating of a sonic boom? gonna be hard to answer that without getting into some serious math. The "loudness" of the boom is depended on the size of the object causing the boom. A needle breaking the sound barrier is a lot different than a fighter jet.

Dude. It isn't rocket science. 120 dbs is where instant hearing loss starts

If it measured under 140db at the ear it would classify as hearing safe due to duration of exposure.
