Bloomington, IN installs rumbler sirens in emergency vehicles

Older sirens are not enough to keep citizens aware.

“Rumbler” sirens produce lower frequencies that cut through typical noise-canceling technology. The low sound sirens do not immediately sound like the emergency vehicles we have heard all our lives, so we pay more attention. As a result, they have led to more civilian awareness of emergency vehicles, a reduction in response time for emergency vehicles, a reduction in near misses in intersections and crosswalks, and a cross-department siren option for alerting the public to emergencies.
