More drivers and pedestrians crank their music to high volume to drown out traffic noise. Sadly, this means that police sirens sometimes go unheard.
Enter the Federal Signal Rumbler, a siren that uses two subwoofers and new sonic patterns. These articles from Wired and Gizmodo have more information, and two YouTube videos provide examples of these bone rattling sirens.
I’ve also posted an MP3 file here.
The deep tones in these videos are the Rumbler in action. I hope you don’t hear one this Memorial Day weekend. Stay safe!
