"An Improved Loudness Indicator"

The standard type VU meter has for many years been employed almost exclusively by broadcasters in the United States as a program level indicator. A new unit which should give better indication of peak loudness has now been developed and is being evaluated. This unit operates within the range of time constants specified by the FCC for transmitter aural modulation meters. A field test is now in progress, with a number of the new indicators in various studios throughout the country.
