The Rumbler: The Fuzz supplies the sounds, you get out of the way
Police and rescue vehicles pump out an array of aural and visual warnings to tell motorists and pedestrians to get out of the way. With distractions like cell phones, MP3 players, eating on the run, and applying a fresh coat of Revlon, civil servants still can't seem to grab our attention. That's where Federal Signal's Rumbler comes in. The new audio warning system doesn't pierce your ears with loud, screeching sirens. It uses low frequency sounds coming from two sub-woofers and an amp to shake the ground in ten second increments. The pulses can be felt 200 feet ahead of the vehicle, giving motorists plenty of time to clear a path in times of emergency. The new device is now being used in the U.S., though we've never felt it, so the next time you hear kickin' bass coming up from behind you, it could be Shaq or it could be the fuzz. Either way, it's best to just clear a path.
