I just got an AAC-M42000 suppressor for my Bushmaster (still waiting to get it). One thing that many people don't realize about the noise reduction in decibels is that it is a logrithmic scale. So compared to a -10db reduction, -20db is ten times the reduction. -30db would be 100 times as quiet as -10db. So if you compare a -30db to a -35db, it doesn't seem like that much of a difference on paper but the -35 is five times quieter!

Hey VUDPblue, I think you should change your signature:
Although silencers have never been banned across the whole US by federal law, there are 15 states that do not allow civillian ownership of silencers, thus possession of a silencer in one of these states is a felony!
There are many state laws that conflict with federal law, but if either one outlaws something you have to follow that law, even though the other may allow it. For example, here in Denver you can legally own small amounts and smoke marijuana even though it's against federal law. But I've never seen anyone light up in public!
You could change it to say, "Silencers have NEVER been illegal in Colorado!"

Check out www.texasguntalk.com Talon Arms is a forum sponsor on there and they're a class III dealer.

Give Craig a call at www.rcsguns.com great guy to work with. Stocks just about all the big ones and VERY reasonable title II transfers if you buy from somebody else. he lives in Anna but works and will meet you in Addison. Tell 'em Jeff sent ya.
The change in noise intensity can be expressed as 10^(dB/10). So reducing noise by a third is 2 dB, a 5x reduction is 3.2 dB, 10x is 10 db, 100x is 20 db, 1000x is 30 db and so on.
From what I have read, if you can barely hear the difference between two noise levels, then one is triple the intensity of the other, or a 2 decibel difference. So when my form 1 can sounded just a bit noisier than an AAC can I shot next to, it was really three times louder.

Oops...
Sound measurements are different, they are measured logarithmically. Without getting into the numbers, for values expressing loudness in dB (SPL) you're actually involving a difference in sound pressure levels, not an absolute. It all works out that an increase of 20 dB (SPL) equals a ten fold increase in sound pressure. As a rule-of-thumb, a 6 dB increase doubles the sound pressure. For a conversion calculator click here.

You both are partially correct, logarithms are involved -- as are many quantities when great ranges are involved. However you fell into a common trap. We're familiar with the logarithmic (base10) Richter Scale of earthquake magnitudes -- for each whole number you go up, the amplitude of the ground motion recorded by a seismograph goes up ten times. This is a typical scale that's expressed logarithmically.RAnb said:
