On December 13, 2011, the Federal Communications Commission (FCC) issued a ruling in which it layed out its rules of enforcement for supporting the provisions of the CALM Act (Commercial Advertisement Loudness Mitigation Act). The CALM Act requires the FCC to regulate the audio of TV commercials from being broadcast at louder sound volumes than the TV program material they accompany and requires the use of technology to ensure that commercials will be played at the same volume as the program.
