I found two different answers in my search.
One says 100X as loud. The other says 4X as loud.

If you're in a tornado, I'd say you'd have bigger things to worry about.Wow did not know how loud inner tornado was. That's pretty crazy considering I've been about .25m away from an AR-15 when it went off with just a little ear protection on (ear plug was very loose). I can't imagine then what the tornado would feel like. My ear rang for a solid 2 days.
It's 20 dB louder.
It's a doubling every 3 dB, so around 100X the sound power. You won't perceive that as 100X though. Some people say that it sounds like 4X as loud but I'd guess that'd vary.
I guess to put it another way:
+3 dB seems a little bit louder to us humans, but it takes twice the power to achieve that. So, if you find your 80 Watt per channel stereo isn't loud enough, you'd probably want to get something like a 200 Watt per channel amp (assuming the values are measured the same way). Getting an amp that does only 25% more at 100 Watts wouldn't help you, since we'd perceive that as barely any louder.
Hearing loss isn't that simple. There seem to be three categories of people.Is everyone who's been in the army slightly deaf?
Hearing loss isn't that simple. There seem to be three categories of people.
1) Those who are born with genetic hearing loss.
2) Those who are born with genes that make them susceptible to hearing loss after exposure to loud noises.
3) Those are not genetically susceptible to hearing loss after exposure to loud noises and require major trauma to get hearing loss.
Most people don't know about category #3.
Just being exposed repeatedly to loud noise is probably not enough to cause hearing loss. You also need to be genetically susceptible to hearing loss caused by loud noises. So, in short, no not everyone in the army is slightly deaf.
A good rule of thumb, is that if your ears hurt or ring for days afterwards, then you might have harmed your hearing if you are genetically susceptible to it. If not, you probably didn't harm your hearing.

Note: I'm not an expert in hearing loss. Also note that I've been flamed here and elsewhere for talking about #3 before. People hold the concept that any loud noise causes hearing damage as very near and dear to them.
Is everyone who's been in the army slightly deaf?
Can confirm, repeated gunfire with inadequate hearing protection will damage your hearing.
I double up with plugs + electronic muffs to avoid further damage. One or the other isn't enough unless you shoot 100% suppressed.
