Now, the next question is
"where did the term VU come from?"
The term VU as I recall stands for "Volume Unit" . I believe there was a
section on a very old NAB looseleaf handbook that had an entire chapter
devoted to this subject. It was a joint committee that wanted to get away for the
old 500 Ohm dB meter standard that was a peak device that was used in the
twenties. "0" dB on the meter was about 30% of scale an that was the standard
level. The joint committee was telephone company and broadcasters.
