If it doesn't say that zero dB ought to correspond to 0.00001, it's damn 
wrong, because 0.0001 corresponds to 20 dB (in Miller's units).

yes and no, it's still meant to be an affine function away (ax+b) from the 
log of the voltage, assuming a distorsion-free rendering with a uniform 
response (... as if that existed ...).
