The sound of the TV drowns out the sounds of the refrigerator, the heat/ac, the washer/dryer, the people walking up and down the stairs outside my front door, the cars driving by, and the car doors in the parking lot. These distracting sounds, of course, don't all happen at once, but the general problem is that because they are unpredictable sounds, they almost always catch my attention when the room is otherwise silent. With the TV on, I rarely notice them, and I usually keep the TV volume low enough that it only distracts me when my brain notices something interesting happening. Granted, most of the time I only use the TV as background noise when it's showing something that I've already watched, or when there's a sporting event on that I only partially care about, which helps my brain recognize the interesting parts.
