David,
        My memory of this feature is that it can vary from component to component [I
don't believe it's like a specific circuit design], but it typically amplifies
the lower registers/tones. (I'm not sure about how one would create false tones
or imply loudness -- I must have slept through that entire chapter in my physics
class.) I think a number of modern boom-boxes call their versions of the
Loudness button something like "Bass Boost." Have you condsidered testing
various Loudness buttons -- maybe comparing the difference in frequency or
volume?
Good luck,
El Troll
