i hate it when you are watching tv and when it goes to commercials it BLARES out sound louder than the show.. and i also hate it when you flip through channels on tv and each channel is on a different volume!! my dad claims that there used to be a law or something against that when tv first came out but OBVIOUSLY that isnt the case anymore!! anyone else driven crazy by this?? do you think they will ever make an option on a tv to where it makes all sound the exact same level?? i would LOVE that!! i watch tv while my hubby sleeps and i never know while flipping through the channels if i am gonna wake him up

Believe it or not, it really isn't louder; it just SOUNDS that way. I was a television engineer for quite some time. There's a device we used called a compander (compressor-expander) that compresses the sound in such a way that it sounds louder, but the peaks are still the same as the program.

Thanks for explaining that secret, Vlad. You didn't mention here what a good husband you are, about turning down he TV when your wife with sensitive hearing gets on your case about the noise. LOL You're the best!! Love Your FAvourite Wife

The sound is compressed and pushed up near the upper limit. To my knowledge, it is still illegal to actually boost the sound above a certain level. I just sounds to the human ear like it is louder. If you were to look at it electronically, you'll see that the peaks are the same, but the valleys are much higher.

Yeah!! When my husband and I are on the phone and he has the TV on in the background, or when we are together and the TV is on, I always react to the loud commercials, and make him turn them down or mute them. I don't care if it's only temporary, my head just can't take that noise!!!!

hi moonlit! oh yeah, that is completely annoying alright. i hate that. i remember when i was working for a local cable company, our head-end technicians would really make sure that everything is modulated because my boss (the owner of the company) hates it when he surfs channels and the other channel is so much louder that the other. he knows that there are other people who care about that too. but ever since he sold his company to a national player, the quality also diminished. too bad. but yeah, i don;t like that too. i get jumpy because i get shocked when the sound volume suddenly changes. good day and God bless you!
