Trouble is, Pete, that it's been found that when folks are subjected to "inaudible" ultrasonic energy at high levels, it makes them very irritable. You may keep the dogs away but draw their owners brandishing shotguns!

Anyway, you ought to be able to use a simple oscillator running at the frequency of interest, say 25KHz - 30KHz, to drive a common stereo amplifier that puts out around 100 watts. Most stereos will have a response that'll go that high. Then connect the output of the amp to a standard higher-power tweeter for speaker systems so that you get better efficiency.

Tired of the poop?
