Trouble with dBmax/F3 & the mystery of 2.31 |
|
|
|
|
I recently posted that the formula for dBmag:
dBmag = 10*LOG(Fr^2/((Fr-1)^2+Fr/Qtc^2))
Seems to be giving me results lower than expected...
It appears if I divide dBmag by exactly 2.31 then
I do get dB values that are consistent with other
SLP graphing applications and the F3 formula:
(F3 = Fb*((1/Qtc^2-2+((1/Qtc^2-2)^2+4)^0.5)/2)^0.5)
Any thoughts what may be going on here or what I'm missing?
