When I talk about a sonogram, I mean the graphic display with time on the X=
axis, frequency on the Y axis, and amplitude by image density or color ran=
ge. When you talk about measuring small differences in amplitude I think yo=
u're talking about a spectrum analysis graph, frequency on X and amplitude =
on Y. Agreed, you can't see fractions of a dB on those, at least the ones I=
use.
