In a unanimous vote Tuesday, the commission approved new rules to implement the Commercial Advertisement Loudness Mitigation Act, or CALM Act, potentially ending an incessant annoyance of modern life.

...Under the order, TV broadcasters and pay-TV operators are required to implement a "best practices" technical standard, developed by the Advanced Television Systems Committee, a nonprofit TV standards-making body, and known as ATSC A/85.

The rules will eventually lead to testing for all commercials aired on TV to ensure that the volume doesn't suddenly jump up when commercials come on the air. TV operators could face commission action for a violation if the FCC determines there is a pattern and practice of violating the rules.

TV stations, cable companies and other video programming distributors will have one year to comply with the new rules, unless issued a waiver by the FCC.
