[Asterisk-Users] Zap (analog line) and volume

[Steve Mann]

Haha, this is true....it reminds me of my loud obnoxious car audio days,
competing in the dB drag events....
I remember people telling me how they had to spend thousands of dollars to
double their amplifier wattage just to get 3 more dB on the competition.....

It's funny how now when some guy pulls up with his stereo thumping, I feel
annoyed....where did my youthful carelessness for my hearing go? :)

anyway, off topic, just feeling nostalgic....

Actually, that's not true.  Each increase of 3.0 dB doubles the *power*.
But the human ear's response is logarithmic, and the decibel scale is also
logarithmic to reflect that.  1 dB is the smallest change in volume most
people can perceive.
