Pop-up advertisements are most commonly thought of as small windows that pop up on your computer in order to display a particular ad. Some pop-ups, however, play a brief audio clip instead of displaying an advertisement. These pop-ups can be particularly annoying as they may go off while you are sitting in a quiet place, such as a classroom or the library. Fortunately, most Web browsers provide users with a way to block most, if not all, audio pop-ups.
