I would pay to see this. Gold. A few years ago I gave into the frustration and decided to rig up a horn system of my own. I got a car horn from a wrecker, mounted it to some sort of relfector bracket on my headset, and drove it off 2X12V emergency light batteries which I wired in series for 24V overvoltage action. I shoved the 7 lb of batteries in some big fred seatpack and wired it up with a bar mounted thumb switch. The horn was so loud that it would make me jump a little every time I hit the switch. It was a liberating experience to have a horn which outperformed the cager horns-Priceless to see the look on their faces when I'd honk back at them-and it was louder. One time I blasted this delivery truck that pulled in front of me, and the driver was so scared he dropped the clutch and stalled the engine. He was looking around frantically for the car that he was about to hit, and only saw me laughing my butt off. Abnoxious? Yes. Fun? Naturally.

After a couple of weeks, the car horn burnt out, probably from excessive voltage-(or perhaps excessive use?) I'd love to make something like that again, only with a more efficient buzzer/horn and a more compact battery. The air zound is OK, but it really is too bulky, and the mount is kind of inelegant.
