Commercial Advertisement Loudness Mitigation (CALM) Act

During TV viewing, you may notice an increase in volume between programs/shows and commercial advertisements. At times, commercials or advertisements that are inserted into standard programming spots may be inserted with a volume level that is greater than that of the programming.

Starting in 2013, the Federal Communications Commission (FCC) rules require commercials to have the same average volume as the programs they accompany, Commercial Advertisement Loudness Mitigation (CALM) Act.
Charter proactively monitors the programmers and takes steps to ensure that these requirements are met.

Many new TV sets have the ability to eliminate volume differences between programs and commercials. These functions usually need to be "enabled" or turned on through the televisions "set up/audio" menu. Some home theater systems also offer audio control options that help control volume differences. Refer to your TV and audio equipment manuals to determine if your equipment has these options.

To submit an investigation request form for volume differences between television programs and commercials please visit https://connect.charter.com/calm.
