[BC] Audio levels

[RichardBJohnson at comcast.net]

I suppose I should not reference Wkipedia because Mr. Fry will
simply modify the Wikipedia article to suit his own purposes
as he did the on the Folded Unipole Antenna article I wrote
referencing expert sources.

http://en.wikipedia.org/wiki/DBm

There is a word (or two) for this, but it escapes me. I left
his edits alone so the experts can observe how stupid
they are.

Now he can go modify the dBm article as well.
