Came across this usually dont like to post links to other forums but this is pretty intersting what he has found so far

The poster is measureing the DB of a gun Fired with different loads in the posters own words

"I am trying to factor in sound for choosing a home-defense weapon so I did some sound testing today"

Im going to read though it more

Everything will be damaging to hearing somewhat if unmuffed but still intresting none the Less

Give some feedback Bud - sounds interesting.

I have the feeling that levels will be up around 120-130 dB peak - which is well up there for damage to ears. Worst I think is very confined spaces where sound cannot dissipate, plus the peak is effectively a short duration shockwave - about the worst for ear drum.

I am imagining even my NAA mini with 22 mag's will be well painful in confines of a room. Outdoors certainly not gonna be quite so grim.

IIRC dB's are not absolute units but, relative to some chosen datum - with sound I seem to recall it is a measure of energy, on a logarithmic scale - each 3 dB step is a doubling or halving.

Yea, dB is a logarithmic scale, and each 6 decibel increase is equivalent to a doubling of actual sound pressure.
