NEW YORK TV viewing could soon sound a little calmer. The CALM Act, which limits the volume of TV commercials, goes into effect today.

CALM, Commercial Advertisement Loudness Mitigation, is designed to prevent TV commercials from blaring at louder volumes than the program content they accompany. The rules govern broadcasters as well as cable and satellite operators.

The rules are meant to protect viewers from excessively loud commercials. The FCC adopted the rules a year ago but gave the industry a one-year grace period to adopt them.

Suspected violations can be reported to the FCC on its website, fcc.gov.
