[QUOTE="hojna15, post: 3455989, member: 570046"] My friend and I heard on the radio that there was a crazy new addition to the cop cars in Washington, D.C., It was said that the cop cars were going to be fitted with a powerful amplifier and a sub woofer system so that drivers can now hear and feel them coming as their so called ground shaking, loud systems vibrate the concrete so that it alerts drivers to police within 198 ft. of their vehicle. Heres the site and article where we also found it, and the radio station was 101.1 the WRIF. I think it's pretty crazy and wrong in some way, I'd like to see how they set it up though, cause i do remember jamie and adam doing an episode of mythbusters on vibrating a bridge down, and i think it tool something like 8 hz, maybe thats off. From, GOINDEF from cardomain.com [URL="http://www.news.com.au/story/0,23599,22666759-38198,00.html"]http://www.news.com.au/story/0,23599,22666759-38198,00.html[/URL] US police cars fit ground-shaking sirens From staff writers October 29, 2007 05:29pm Article from: NEWS.com.au Font size: + - Send this article: Print Email A US POLICE department has launched the ultimate siren to make sure everyone knows officers need room to drive, the ground-shaking "Rumbler". Patrol cars in Washington DC are currently being fitted out with the high-tech siren, which projects soundwaves inaudible to humans but powerful enough to shake everything around the vehicle. One of the officers using the new siren, Lou Schneider, told The Washington Post that the new gadget attracted a lot of attention. "You know when this is coming up behind you," Officer Schneider said. "It vibrates everything." According to the newspaper, the Rumbler consists of two subwoofers and an amplifier that pumps out soundwaves that people can feel from up to 60m away. Police officials told The Post that they expect members of the public to be startled when a cop car drives by with its sirens blazing and the ground it touches shaking. Several other police departments in the US are testing the new sirens, including in New York. [/QUOTE]
