Starting Today, TV Ads Can't Blare Anymore FCC implements rule toning down volume of commercials By Newser Editors and Wire Services Posted Dec 13, 2012 3:24 PM CST 48 comments Comments You can kiss overly loud commercials goodbye. (Shutterstock) (Newser) – TV viewing could soon sound a little calmer. The CALM Act, which limits the volume of TV commercials, goes into effect today. CALM stands for Commercial Advertisement Loudness Mitigation. The act is designed to prevent TV commercials from blaring at louder volumes than the program content they accompany, and it applies to broadcasters as well as cable and satellite operators. The FCC adopted the rule a year ago, but gave the industry a one-year grace period. Suspected violations can be reported by the public to the FCC on its website.
