Why are the television commercials louder than the shows?
The people who make television commercials compress the audio. The spaces between words become squeezed together in an attempt to make the maximum use out of a mere 30 seconds. In this process, all words become virtually identical in volume – a volume that appears to peak on audio meters. Television movies and programs also have audio levels that peak, but this occurs more infrequently. Generally, the producers of non-commercial programming prefer having a variety of audio levels. Quiet moments can be used for great dramatic effects. There is no time for that luxury in the much-shorter commercials.
