Answer 1

You didn't say if this whole affair needed to be portable, but generally portable devices aren't going to have enough audio power to overcome much distance or ambient noise.

There are very simple devices called "waveform generators" or you may even be able to search for a "tone generator" device with an output. You then connect the output of one of these to an audio amplifier - say a car amplifier if you are going to be mounting this to a car. Then connect the car amplifier to a large PA type speaker. You would then be able to create VERY loud sounds to get the attention of everyone within a very large distance.

If you get enough audio energy, the people you are trying to notify wouldn't even have to hear the sound (think ear plugs) - they would be able to FEEL the sound. This kind of volume would probably take at least 100W of audio power.

Who, or what are these hand fellers, and must they be eradicated?
