Decibels are not quantities of anything, not even sound.They are the ratio between 2 different levels of power.Bels(in this case) are the relationship between amplitude and energy, decibels are 1/10th of a Bel.Bels are logarithmic, and its complicated even further by the fact human hearing is logarithmic as well.

3 dB = double the intensity
10 dB = ten times the intensity, but twice the perceived sound level

In terms of amps and speakers:
2X the amplified power = 3 dB
2X the speakers = 6 dB
2X the perceived loudness = 10 dB

Engines:
2X the horsepower = 3 dB
4X the engines = 6 dB
10x the horsepower = 10 dB

difference between 100 dB and 200 dB = 10x10x10x10x10x10x10x10x10x10 or 10 billion times the intensity=2x2x2x2x2x2x2x2x2x2 or 1024 times the perceived loudness

anyone have a spare brain?

ya I'm lost also

You really don't need to understand it.If you ever needed to figure out dB(I don't know why you would), just get a calculator that has a Log(arithm) function.The log of 2(2X power) is .301, which is in Bels, so in dB it's 3.01(commonly refered to as 3 dB).Log of 3 is .477 or 4.77 dB.Log of 4 is .602 or 6.02 dB.Log of 10 is 1 or 10 dB.

In terms of human sound perception, it takes 10 times the sound output, for us to perceive it as a 2X increase.

I remember just a bit of this shit from my loud stereo days 10 years ago.

how is the standalone coming?
LOL!

Thanks for clrearing that up, Eric.

It appears we've weeded out the intellectuals from the dumbasses. ;)

[Enes]

speak for yourself Mat!

i am still not weeded out!

Yep, I admit it, I'm a nerd.But it's OK, because the chicks still dig me
