Is there a way you can give us the option to turn off sound except the page we are actively viewing?

As advertising is becoming more and more prevalent and is being allowed to automatically start running on a page we need a way to either prevent that or at the very least turn an option to off any sound that is coming from each individual page/tab that we have up but is not the currently viewed page. A group option would not work because of things like Pandora so it would have to be on a tab by tab basis or like popups on a browser basis with exceptions (although that could lead to a lot of exceptions). It seems that I am watching something and on another tab an advertisement will auto start and drown out what I was watching. Then I have to go and locate the page - sometimes difficult if you have a bunch of tabs open at one time like I normally do - and turn off the ad or mute the ad... something along those lines. So figure out how to kill the ads.
