If you can show audio peaks on the commercials set more bits than does the program material, you can cite the media provider as not being in compliance with the law. This is straightforwardly measurable.

But, there are well known techniques that compress the peaks allowing the average power in the modulating signal envelope to increase. So it's possible to make the commercial audio sound louder even if the audio peaks don't set as many bits.

That's more the essence of perceived loudness.

The FCC handles the complex technical details of a simply worded law. So, somehow, they must determine exactly what loudness is and establish a technical standard for measuring it though its rule making process.

FCC to Shush Commercials
By TRAVIS SANFORD

WASHINGTON (CN) - TV broadcasters will have to turn down the volume on commercials, at least to the level of the programs they accompany, according to a proposed rule issued by the Federal Communications Commission.
The FCC must adopt regulations requiring broadcasters to limit the volume on the transmission of commercials by Dec. 15, 2011 to comply with the Commercial Advertisement Loudness Mitigation (CALM) Act.
Congress passed the Act in response to viewer complaints about the sudden increase in volume during commercial breaks.
According to the FCC, change in volume at commercial breaks has been a long standing complaint of viewers. The problem appears to have been exacerbated by digital broadcasting technology, which allows the creators of programs and commercials to encode more dynamic sound options than were possible during the age of analog TV transmissions.
By mandating that commercials can not be louder than the programs they accompany, the FCC says the Act allows it to avoid making subjective judgments about the overall volume of broadcasts.
Broadcasters, including cable and satellite services, will have one year to implement the agency's final regulations.
The FCC is requesting public comments on implementation of the Act's requirements until July 5, 2011.
