Not sure if any of you have seen/heard this, but the Air Zound is a 115 decibel horn made for bikes. According to Delta's tag for the device, it's the loudest horn you can get.

I honestly don't know if it's the loudest, but I can attest that this sucker is _LOUD_. I ordered one last week from airbomb.com and it finally came in today. When I tested it, I heard ringing for 10 minutes afterwards.

What's cool is that it uses a standard bottle (included) as an air resevoir. It also has a volume control knob which is pretty cool. They advertise that you can get 50 "blasts" out of it when the bottle is charged to 80 psi, but that's only on the lowest setting. On the highest, the packaging says 30.

Still. I bike commute to/from work (starting a new job monday!) and I'm tired of trying to get driver's attentions. I think this will end up doing the job.

Now I've got to find one of our sound meters and see what the actual decibel rating is from 20 feet.
