If you’re in Manhattan and suddenly feeling some not-so-good vibrations, it could be the effects of the New York Police Department’s latest siren, called the Rumbler.

“It emits vibrations that can be felt, so drivers, even with their windows rolled up and stereos on, can be alerted to the approach of emergency vehicles,” Paul Browne, a spokesman for the Police Department, told The New York Post.

“It also gets the attention of pedestrians with headphones or iPods or who may be otherwise inattentive to conventional sirens,” he said.

The Rumbler, which is manufactured by the Federal Signal Corporation, has a range of 200 feet and can be used in conjunction with the Police Department’s existing five siren options.

The department said that 25 cars were fitted with the Rumbler last week and another 132 are getting the super siren on Monday.

According to an article The Times wrote about the Rumbler two years ago:

Robert S. Martinez, director of the department’s fleet services unit, says the Rumbler has brought pedestrians and traffic to a dead stop every time he has tried out the test model. Departments in Alexandria, Va., and elsewhere in the Washington area already have Rumblers, according to Tom Morgan of Federal Signal, a leading siren supplier. It works like a bass-heavy boombox, sending out vibrations through two woofers.

The Rumbler has been in use by the police in Washington since 2007. Other cities have also adopted the siren. Here is a video of a Kansas City, Mo., police officer giving a demonstration of the Rumbler.
