Inspired by decades of consumer complaints, Congress is possibly days away from passing legislation that would ban TV ads that blare louder than the programs they're on. The Commercial Advertising
Loudness Mitigation, or CALM, Act follows rules on how to measure and clip broadcast volumes.
Up to now, broadcasters mandated that ads should not exceed the "peak" loudness of the program
being interrupted. Often, that "peak" was a mere spike such as a gunshot or a scream. Ad producers crank the noise level to just below that peak. Result? Viewers being driven nuts.

ears.
