A New Loudness Indicator for Use in Broadcasting
Bronwyn L. Jones, Emil L. Torick · SMPTE Journal · 1981
New psychoacoustic studies have been carried out, resulting in the design of an improved Loudness Indicator. The new Indicator utilizes principles similar to the CBS Laboratories Loudness Level Monitor developed in 1967, but also includes certain modifications which improve its accuracy and readability. This paper describes these modifications and presents the results of validation studies comparing the new Indicator both with the original CBS device and with listening panel judgments.
