There you are. Minding your own business and surfing the Web in peace when all of a sudden an unexpected sound comes blaring through your speakers, causing you to leap from your chair and knock over a drink into your keyboard. Ugh!!!
The source of that errant noise turns out to be one of your open browser tabs, whose respective Web page just decided to start playing a video advertisement with a talking dog in it. The problem, however, is that you're the quintessential multitasker with dozens of tabs. So, which bleeping tab is the audio coming from?!?
