OP likely already has his mind made up, wanted to confirm his opinion, doesn't get the db math, and would rather not try to understand it because then his opinion would be wrong.That's not how sound works.... even a 6 db reduction is f***ing huge. 12.5% is a gross misrepresentation of the real life difference.
Decibels are a ten log scale: you can't do a simple ratio like that. In fact, a 20 dB reduction in sound level means a 99% reduction in the sound pressure energy.140 / 160 = 0.875, about a 12.5% noise reduction. Hearing safe is approximately 85dB.
Not quite. You have to distinguish what something "sounds like" and the sound pressure energy that causes the sound. It is the sound pressure energy that is potentially damaging to one's hearing.not exactly. Gunshot hearing safe is around 140 for limited exposure.
Also, Dbs are logarithmic not linear. 140db is significantly quiter than 160.
I think it is every 3db increase is double the volume. so 20 db would make it 6 times louder? I'm sure someone here can correct me.
edit: I had to look it up. It is every 10dbs sounds twice as loud. so 140 to 150 is double, then 150 to 160 is double again.
dBi is an RF measurement; dBm is a power measurement.My work life is in dBs and I still f*** it up.
(dBi & dBm)
Agreed....Shoot a 300 AAC bolt gun with sub sonic ammo and a can and you can't wipe the smile off your face.
As others have said, it goes from single impulse damage to just don't do it a lot kind of damage. It's like the old hunter's response to almost every question about hearing loss from hunting, "What?"
