  • Abstract
    A loudness limiter which reduces disparity in loudness levels, when a program is controlled on a vu basis, has been developed by CBS Laboratories. The device evaluates the loudness level of the program by a "loudness level summation" method described previously by the authors, and automatically reduces the program level when a preset threshold is exceeded.
