Is a device made for a TV, to stop the occasional loud increase contained by volume on some commercials?
Answers: It's technically possible but no TV have one yet, although some TV's own an AVL (auto volume level) setting which helps for a moment. Until they do you'll have to ride the Mute button.
Technically speaking, it's possible, but no course for the average person to do it. Read up for a time on Dolby noise narrowing to get an theory what's happening.
Take a regular TV program. There's adjectives kinds of audio level going on in the program, loud, peace, soft, hard, it's call Dynamic Range. Electrically, it takes up seriously of space, too, sort of like bandwidth. So when they broadcast it, it go through a process called compression/limiting. Basically flattens out that dynamic array.
Now, when it gets to your TV, it's going to nouns pretty dead. So your TV have, as part of its audio circuitry, an expander that restores the compressed audio wager on to it's normal continuum.
Pretty good, so far. Now your program sounds commonplace. But then along comes a commercial. It's not really any louder than the program. But there's also no Dynamic Range. They're chitchat at a constant peak volume. Your TV think it's been compressed, so it expands the already loud audio so that it's very soon louder than it was intended to be.
So, it's not the TV stations that are doing it. It's everyone's individual TV sets. And the individual way to get rid of it is to disable the TV's audio expander which makes your TV program nouns like that guy on the Clear Eyes commercial.
