Could either of you assist me in a search for sound wave files that are
above the audible range of humans? Where would I search to find more
information on this. I know the basics involving a dog whistle... but are
there any downloadable wav files? Could I produce such sound waves and
record them?

I have been told that prolonged exposure to such "sound" has deleterious
effects on a person's mental state. I don't know if that is true.

I hoping to keep the raccoons out of the garbage.

...any help in direction would be appreciated.
