Oh good—because police sirens just aren't loud enough, now more cops will be able to blast the "whooping vibration-siren system" called The Rumbler when they're racing to the scene of a Dunkin' Donuts or Magnolia Bakery. You'll recall that in 2009, the NYPD expanded a pilot program testing The Rumbler on 150 squad cars. The Rumbler is the siren that has "the distinct advantage of penetrating and shaking solid materials, allowing vehicle operators and nearby pedestrians to FEEL the sound waves and perhaps even see their effects through a shaking rearview mirror." And now another 4,500 cops will be able to push a button and make your trousers vibrate. more ›

After a successful pilot program, the NYPD is adding a new siren called The Rumbler to over 150 patrol cars; this bad boy blasts a palpable sound wave that can be felt up to 200 feet away. According to The Rumbler's manufacturer [pdf], the siren has "the distinct advantage of penetrating and shaking solid materials, allowing vehicle operators and nearby pedestrians to FEEL the sound waves and perhaps even see their effects through a shaking rearview mirror." The company also warns that the siren and speakers "may cause hearing damage," and those who use it are encouraged to wear ear protection. more ›
