Super Sonic Nausea device

Billed as a "revenge product," the Super Sonic Nausea device is the "government model" of the regular Sonic Nausea device that "generates a unique combination of ultra-high frequency soundwaves which soon leads most in its vicinity to queasiness." I think it basically makes a high-pitched, loud, and annoying squeal. It's $99 from law enforcement and military gear supplier Shomer-Tec. From the product page:
 Media Images Ssn Med31 Speeches, demonstrations, crowd dynamics, etc. - this device has been used to "influence" more of these than you might expect. Deployed near the podium, you might just have a case of an increasingly un-impressive speaker with diminished sharpness and lacking concentration, or perhaps is even unable to complete his presentation. Or, loitering youths on your property might be enticed to move along with no confrontations necessary.

  1. It might be bunk. While low-frequency sound waves can cause visual disturbances, feeling of awe or fear, and discomfort, there is no known frequency that causes nausea when transmitted through air.

  2. Well, “Super Sonic Nausea” device sounds more intimidating than “Super Sonic Annoyer.” Although the latter sounds more fun.

  3. I saw this after the article 1-2 weeks ago about the “slap cap” or w/e it’s called, and was interested.

    it’s “no [u]known[/u] frequency” that’s the key. i imagine there are well-protected lists of window frequencies found to induce all kinds of biological responses, in addition to some of the more well-known ones that cause hallucinations.

    this could operate in ultrasound as well as infrasound, though i’m guessing it’s the latter, since there’s two speakers. hopefully someone with $99 to waste will buy this and reverse engineer it to see what frequencies it produces

  4. So what’s it do?

    Play Whitehouse – Cream of The Second Coming or something?

    Man that record makes me feel ill and super uneasy every time I manage to make it through all 4 sides.

  5. This has been offered for sale on their website for years now. It is interesting to see this write up about it. I almost bought one in 1999 just because it seemed like fun.

  6. These look like piezo tweeters, so it will definitely be high frequency.

    Google image search for piezo tweeter shows me the exact same tweeter as 3rd and 4th hits, where the 3rd is a cabinet with 6 of ’em for 20 uk pounds.

    They deliver 94 dB/watt (not terribly high). Nine-volt batteries store about 5 watt-hours.

    BTW I like the description on the box. It is a kind of cop-speak. “DISPLAY, RADIANT, ELECTRON BEAM” sounds a lot better than “17 inch CRT monitor”.

  7. Back in the 1970s a group of physicists were selling a digitizing tablet based on ultrasonic sound localization. (Basically, the pen emitted ultrasound, and it was tracked and triangulated by a set of microphones. Most tablets used radiowaves, magneto-restrictive wires or other silent technologies.)

    I remember the demo quite clearly. First came the headache. Then came the dizziness. Then came the nausea. I nearly puked. I remember gasping with relief out in the hall. Interestingly, I was the only one in the group affected. My hearing was probably a lot better back then. In any event, I’m glad the technology never caught on.

  8. Do not be surprised, this thing actually does work on certain people as described ( I have one). I had to MOD the device with a 470+ uF 50V cap at the battery terminal to make it sound right and work properly.
    Kids can actually hear this thing, but many older adults cannot, but it can cause ill effects from mild headaches and vertigo, to a nasty case of nausea. (hmm)

  9. If I can make people blather like Jim Carrey did to Steve Carrell in that movie, I want this with a wireless remote so I can turn it on everytime that (insert expletive here) boss of mine opens his trap at the next sales meeting. HooRaa! They could charge me $1000 if it did that!!
