D.C.'s High-Tech 'Rumbler' Siren Emits a Low-Frequency Vibe You Can Feel

Washington Post/October 29, 2007

With his lights and sirens blaring, D.C. police officer Lou Schneider

raced to an emergency call, past dozens of startled onlookers standing

on the crowded streets of the city's Chinatown area.

The ground beneath Schneider's patrol car literally was quivering.

Officer Lou Schneider says the Rumbler gets motorists' attention and

clears intersections more quickly than using only a conventional siren.

" You know when this is coming up behind you, " said Schneider, one of a

few dozen D.C. officers who are using the department's newest sirens

-- the ones that people can feel as well as hear.

" It vibrates everything, " he said.

 

Meet the Rumbler.
