Even though you've been warned against going to bed with the TV on, you feel the talk show host's voice helps you relax. But the sudden shift to loud or high-pitched commercials could be affecting your rest. The recently passed Commercial Advertisement Loudness Mitigation Act won't solve this problem either. Most commercials don't actually exceed the recommended volume limit, noted an article in the April 2011 issue of Wired magazine
; they only sound louder. In a TV show, most of the noise comes from people talking, with a few bursts of, say, shouts, horns or crashes. During a commercial, though, the volume is elevated to just
below the maximum limit for the entire
30 seconds. So you'll still be affected by those random, extended peaks of sound. For the best rest, say goodnight to Dave, Jay and Conan before getting into bed.
