I experienced 9 dB and 12 dB as twice as loud, but exactly 10 dB.
3 dB, 6 dB, "9 dB and 12 dB, instead of 10 dB" ... for my emotions there
is a math pattern.
Hi All
I was under the impression that every 3 db increase doubled the volume
and you needed to increase the power needed by a factor of 3 . Things
could have changed by now but this is what I use.

And ... 1 KHz sine wave vs music @ the same dB ... the basis has to be
noise, representing the frequency spectrum regarded to the sensitivity
of the human ear?! Or to usual music, usual speaking? ... dB is some
artificial thingy itself.
A paradox, dB for audio claims to be related to the human ear.
I heard about 3 dB, 6 dB and 10 dB as twice as loud.
