The FCC adopted a law to keep TV commercials back in 2011, but it's decided that it's not enough: from June 2015, there are set to be further volume reductions on loud ads.
The Hill has spotted that the FCC is planning to update 2011's Commercial Advertisement Litigation Mitigation (CALM) Act. As of June 4th next year, the FCC will be implementing a new 'loudness measurement algorithm.' While the measure currently used to judge how offensively loud a commercial is average volume, the new algorithm will measure quiet parts of the ads, that can bring that average down, and discount them. Quite why that wasn't done first time round is unclear, but we're glad it's happening. [FCC via The Hill via Engadget]
