Piezo dog blasts

Piezo sounders can be much louder than the ones used on Dazers and similar devices. They can be ultrasonic, or not.

Like LEDs, they can be purchased separately.

Some of them sound freaky. Like some otherworldly electronic bullfrog croaking, amplified greatly.

They make most dogs stop or turn around.

***
It would not be difficult to set up a bike with two or more of these mounted and wired, with a control switch on the bars. Sometimes dogs don't allow you much warning or time. Quick response is desirable. Hitting the switch and activating the sounders would be very quick.

If anyone tries, or has tried, something like this, please post; it would be interesting to see or read about.

Any supply sites on where to order these things? Maybe one with an mp3 sample file?

I don't know where to buy them, but the alarms used on both the AED cabinet alarms and the fire alarms at work hurt my ears to be anywhere near. It's two high pitched tones that are very close that beat against one another, and it's pulsed quickly. It's incredibly irritating and makes you want to not be there.
