CALM Act Regulates Volume of TV Commercials
The Federal Communications Commission (FCC) established new rules for the volume of television commercials that started on December 13, 2012. The new regulation, known as the Commercial Advertisement Loudness Mitigation (CALM) Act, requires commercials to have the same average volume as the programs they accompany. The CALM Act requires TV stations, cable operators or other multichannel video program distributors to apply specific FCC practices to commercials they transmit.
If you hear a commercial louder than the TV show it accompanies, you can file a complaint with the FCC by providing detailed information about the commercial.
