CALM Act

The Commercial Advertisement Loudness Mitigation (CALM) Act requires the Federal Communications Commission (FCC) to ensure that television commercials are played at the same average volume as the programs they accompany. This law applies to all TV stations and pay-TV providers, such as cable and satellite services, mandating that they use specific industry technology to prevent advertisements from being significantly louder than the show you are watching. For the average viewer, this means no longer having to manually adjust the volume or being startled by sudden, noisy commercial breaks.
