Here is the pest repelling Transonic Bird X ultrasonic sound generator.
Now, I'm sure some have heard of ultrasonic plant stimulation. Here's a little yahoo answers about it:

Its pretty well known that ultrasonic plant stimulation will increase growth rates, but the following scholarly article goes into specifics of ultrasonic stimulation effects.
http://link.springer.com/article/10.1007/s00253-002-0971-2#page-1
Now, if you read that article, you will see that the short bursts of 38.5 kHz ultrasound causes the plant cells to react defensively and increase secondary metabolite production for 24 hours. The link below is wiki secondary metabolites:

If you read the above you will see that secondary metabolites are involved with plant health, vigor, and defenses. Please read the second paragraph of the following wiki entry:
http://en.wikipedia.org/wiki/Tetrahydrocannabinol
Yes, THC is a secondary metabolite. So not only would ultrasonic stimulation increase growth but if used in flower, could boost secondary metabolite production... THC...
I believe the ultrasonic sound generator above, purchased online from Walmart, would qualify as a low energy ultrasonic generator. The frequency rating is 3kHz - 40kHz so achieving 38.5kHz is possible. The unit oscillates between frequencies set by user. It has a setting for strictly ultrasonic noise. There are three patterns of oscillation but the manual and specifications do not go into detail about the patterns themselves. I emailed Transonic and they responded that they will get back to me. I will update with experimental pictures and hopefully information about the patterns later.
