A new federal rule will prohibit commercials played much louder than television shows.
The Federal Communication Commission imposed the rule Tuesday, after thousands of viewer complaints.
The rule limiting spikes in volume won't take affect for another year. So you might have to keep your finger on the mute button for a while longer.
By the way, the FCC's authority to enact the rule came in the Commercial Advertisement Loudness Mitigation, or CALM Act.
