LANSING, MI (WTVB) - The volume is being turned down on excessively loud television commercials. Starting today, the Commercial Advertisement Loudness Mitigation Act kicks in. Also known as the CALM Act, the measure was approved in both the House and Senate over a year ago. It requires television stations to monitor the volume of all commercials they air, whether they're local or nationally syndicated spots.

Cable providers will also be required to make sure their audio levels are consistent. Failure to do so could result in fines from the FCC. The agency has set up a hotline for viewers to report loud commercials. That number is 1-888-225-5322.
