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?

 

[fixitfred]

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.

 

[Yosemite Sam]

So is, say, 163db to 160db is a lot?

 

[Coalcracker]

Not a lot from 163 down to 160. I believe the average conversation DB level is 40.

When I get my pistol built, I might be a little scared to shoot it!

They claim 150db is ear drum rupture.

So, shooting an AR pistol in a car without ear protection would be bad, huh?

Definitely.

 

[Fitasc Shooter]

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.

And my hearing sucks from just one or two shots done outdoors.constant tinnitus 24/7

I just tookmy hearing aids out so I cannot hear any of ya!

My problem is my brain interpreting what my ears hear, sometimes all I hear is bghubed miagbugeb ubaguba etc

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
