Been researching blast deflectors.
With a can vs no can, there is about a 3db drop. Been reading on sound, and they say 3db is 50%. But it's confusing, at best. Anyone understnd this stuff?

3db is a doubling or halving depending on which way you go. It's on a logarithmic scale.

3db electronically and acoustically is a doubling but the ear normally perceives 10db as a doubling.

Shooting an AR pistol, or rifle anywhere without hearing protection is bad ju-ju for your hearing

I grew up shooting shotguns, revolvers (.357), 30-30, 30-06, no hearing protection back then. My hearing ie pretty good. But we were outside, not in indoor ranges and such.

Repeated impact noises (gunshot, hammer, etc) as low as 95db can cause long term hearing damage, according to OSHA.

EDIT: Though in all fairness, OSHA also says you need hearing protection to use a vacuum. So take it with a grain of salt.

Same here I think my hearing is following my eyesight and probably my tastebuds too, the older I get the more I can relate to the Pink floyd song comfortably numb :LOL:
