 Commercial Advertisement Loudness Mitigation Act

The Commercial Advertisement Loudness Mitigation (CALM) Act is a United States law that was enacted to address the issue of excessively loud television commercials. Signed into law in December 2010, the act requires that television commercials have the same average volume as the programs they accompany. The CALM Act mandates the use of specific technical standards set by the Federal Communications Commission (FCC), which ensure that the volume of commercials is consistent with the volume of the shows.
