The Rumbler: Coming to a Cop Car near you – Click above to watch video after the jump
If you're walking down the street, you might be distracted with a phone at your ear, or you might be listening to your iPod, or you might just be oblivious. When driving, the car you're in is insulated to reduce the amount of exterior noise that enters the cabin, and besides, you might have a stereo on. This can be a problem for the police, who use their sirens as an attention grabbing device. There is a solution, however, and it's called the Rumbler.
Fitting a pair of subwoofers under the rear bumper and connecting them to the horn, the police are able to grab your attention in a whole new way. The Rumbler produces a tone at the same volume as the sirens, but because its a much lower tone, you don't just hear it, you feel it. CNN Money's Peter Valdes-Dapena explores the Rumbler as fitted to NYPD patrol cars in the clip posted after the jump.
