Interesting links!
I don't know if any illegal aliens (terrestrial anyway) are using such technology, but I do know that sound as a weapon or deterrent has been studied for many years and can have some pretty nasty effects.
I bought a device some years ago that produces a varying high-pitched sound that will drive most people as far away from it as they can get and it runs on 2 AAAA (yes, quadruple-A) batteries!
I have also personally built my own (slightly modified) version of the "Phasor Blast Wave Pistol" (mentioned in one of your links above) from plans supplied by "Amazing Devices" and while not particularly effective as a weapon, people (and animals) definitely don't want to hang around when it's on!
It actually got to the point, when I was younger and living with my parents, that the standard response to any annoying noises, electrical disturbances, etc. was; "Billy... what are you doing now?"
These days I choose to use my powers for good! Okay, mostly for good.
Anyway, while the technology is mostly unknown (thankfully?), acoustic weapons are a fact of life in the modern age, and the technology and knowledge to create them are both becoming much more readily accessable to the common man.
Bill,
At that link I think is the man who made ultrasonics weapon worthy with 4 stacked piezo transducers for the Law and Military (which they all deny exists, but...). Its the interaction effect which makes all the chilling effects (like 4 car alarms stacked and aimed). Silent or just over audible 20kHz is the killer range where repeat cycle duration frequencies go from nausea to hyperactive and 'around' metal is like a microwave and even cotton 'blend' clothing will give you extreme pain, insides jump around, and extreme 'chills' down your spine. Infrasonics also known as subsonics is more wave length determinant and is good only with a car battery, d class 1000W amp, and subwoofers since would require 70+ amp house fuse breaker otherwise. So the new technology ultrasonics can run on 115v or 8 C cel batteries. But if you ever hear (infrasonic) BAAAH BAAAHH BAAAHH outside in front of your house, hold you hand up and you will feel pain come through your wall openings and even through the walls a few moments later.
I am well insulated now and have temporarilly run the illegal aliens out of their house with my 140db canine10. But it took a dedicated 2 months of research, home refurbishments, and painful nights once or twice a week. Illegal aliens (20+) have lived in same house last 2 (groups of) tennants (6 years) so don't expect any different from that landlord this time. Big bucks I guess. And its the first time in my life I never worried about a dog barking. It was a hard lesson, especially the defense, which the illegal aliens and Law haven't figured out to date. They just terrorize people 'hidden' behind boom boxes and people targeted 'never' realize what's going on (pissed off, can't sleep, head aches, ...). I didn't either until complained to law so much that was ALL they did. The first night it was like a haunted house with bed shaking, sounds in house, spine tingles, and energy giving me leg cramps and even 'grasping' my heart! I knew had to figure that crap out fast.
When I find time, really do want to write a book about it. There is nothing about either sound out there except for what I've posted specifically. I've got about 50 links that helped me determine characteristics of both including asking the Professor on that link above. It took a third world retard to show me, but think there HAS to be someone behind massive illegal alien housing profit scheme, or even the County Law itself from massive inconsistancies and conclusive evidence (won't really know until get a $12.2K Thermal Imager to look through walls, but more realistically, get $160 Body Heat detector and $100 Ion Field Detector to SHOW Police how to do their job, lol). Hell, there's 12 Million illegal aliens in Central Florida alone, packed about 25 people average per 2 bedroom flats. The rest of the nation has to be facing similiar circumstances themselves. IN FACT, just driving into town with windows cracked, once I got some unmistakable pains around glasses (steel arm core) temples and naseau effects around a redlight or two (close together). Now maybe the ultrasonics of normal tech devices may have caused it, but...
Here's a good book of the Professors 'Plans' for most of his 'good' stuff from Amazon which I got new about $10, interesting read to show what's out there (Look Inside!):

Security is very important when mixing civilized citizens and uncivlized aliens which the law seems to support more than the citizens rights: and they know it! Already marching for Rights when not even legal citizens
Renting to 20-30 illegal aliens has to be in top 10 businesses in America already. All you need is relentless retarded house warden that can't speak English and a driver/interpretor (so can play Grengo game with Sheriffs interpretor until Sheriffs dieing to get away). Their main pay is living expenses and subwoofer addiction, partially due to the release of endorphins in the body like Cocaine! Then pick up a few $200 totalled trucks for dropping labor off and have some driver/laborer dual jobs. The laborers come home after dark or 8pm and leave by 5am, so just the warden, driver/interpretor, and subwoofers most of the day (either Oompah music or even just BAAAH BAAAHH BAAAHH will do). Other accessories seem to be ultrasonics with canine controller activation and sweep mechanism, class d subwoofer with shotgun miic activation that switches from car to house easily, and shotgun mic so the retarded warden can follow anyone beside them 24/7 for territory expansion and another $10k/mo revenue stream. The laborers seem fine (I think) but anyone involved should be busted from the top down imo.
Its almost seems organized as another one of AG Bush's profit centers other than oil skimming and Chinese commissions
Very interesting INDEED!
