With AI and current technology, it shouldn't be too hard to come up with a device that can sample shouty commercials and automatically mute them whenever they come on. The device could continuously record on a 10-second or so loop and whenever you hit the kill button it would save the current bit and look for matches with any future audio. When it finds one, it mutes it until the sound drops back to a more normal level. Anyone who likes this idea is welcome to borrow it.
