New Colo. Ambulance Sirens Will Vibrate Drivers

DENVER --

St. Anthony's Hospital has new sirens on two ambulances that will vibrate drivers.

Rumbler sirens have a low frequency or tone that send vibrations up to 70 yards away to alert drivers that an ambulance is coming.

Hospital officials said with the increased usage of cell phones and iPods, it has become increasingly difficult to alert motorists that an ambulance is near.

Rumbler sirens are becoming more prevalent throughout the U.S. and have been proven to be more efficient in getting the attention of vehicles and pedestrians as well, according to a news release.

St. Anthony's Hospital has outfitted its two primary ambulances with Rumbler sirens. The hospital said they are among the first emergency vehicles in the metro area to do so.
