I know my design blog hasn’t really been much about design, but that stuff takes longer to blog about and I’m working on a PhD here. Instead, here’s a documentary coming out soon

“Howler” siren

November 14, 2008

Associated Press is reporting that the largest ambulance company in Oklahoma is outfitting their entire fleet of emergency vehicles with a new type of siren that you can feel as well as hear. It uses ultra-low frequency sound that can penetrate into cars to get the attention of drivers on phones or listening to music at earsplitting levels.

Have you ever been passed by a car that had the bass amps cranked up so much you could feel the music? It’s like that, only less musical and more sireny.

Press release.

<tangent>I used to be a firefighter, and I can’t wait until I get out of grad school and have a normal job so I can go back to doing it again. Firefighters and EMTs have really cool stuff.</tangent>

Anyway, while this is meant to get the attention of hearing people who aren’t paying attention, I don’t think you need to try very hard to think of some safety applications of tangible sound for people with hearing impairments.
