Japanese Researchers Develop Speech Jammer: Sweet or Scary?

Keeping a boisterous crowd under control might become a little bit easier in the future. Perhaps... too easy. Japanese researchers Kazutaka Kurihara and Koji Tsukada have reportedly developed a "gun" that effectively silences anyone it "shoots." Early prototypes of the SpeechJammer required the gun to be hooked up to a computer, but rumor has it that they've already developed a handheld version of the device.

The way it's supposed to work is a little bit complicated. An abstract about the project found on the Cornell University Library website explains, "In general, human speech is jammed by giving back to the speakers their own utterances at a delay of a few hundred milliseconds. This effect can disturb people without any physical discomfort, and disappears immediately by stop speaking. Furthermore, this effect does not involve anyone but the speaker ... " Sounds a little complicated, but the video will help smooth things out. Plus, it's kind of funny. Do you think a speech jammer is a pretty sweet idea, or is it slightly too strange for your taste?

    While the idea of thwarting free speech is horrendous the scary part is the reactions from those who are silenced. If a boisterous crowd can't use voice to release emotional pressure they very well may use physical violence. On the sweet side, at times I wish I had an app for that.

    The only purpose I can see this having is to remove freedom of speech. Unless a legitimate GOOD reason for the invention is given, and harsh consequences for misusing it are immediately implemented the device needs to be banned.

    Bose noise canceling head phones I believe could be considered a good use.
    But this could be segregated from the use in protests or other acts of "free speech."

    Those working to create an future view book similar to Orwell's 1984 would like this technology for the upcoming book, 2012.

    In this book a bunch of Mayan mystics will end the world as we know it and turn the humans into uneducated creatures that give their will to a device called tele-vision. The device known in the book as TV gives the masses entertainment and what is called news but is more double speak and spin. Using this the masters of the TV will neatly divide the people into what the book calls the Left and the Right. Pretty strange stuff but entertaining.

    There is a group in it called the spinner heads that follow very closely their spin masters. This is not to be mixed up with records which as historians will tell us were virtually extinct in the year 2012. Instead the masses will be forced to listen to MP3 devices that fill their minds with pleasing sounds as they turn to a kind of breakfast cereal colloquially called mush.

    Sound weapons are a reality.

    We're talking about a directional sound wave generator. The depelopers in the US Government won't comment, so details are sketchy, but the device most likely operates by generating low-frequency sound pulses and sends them toward a target.

    Some earlier sound weapons simply caused pain from high decibel noises (like Mariah Carey), or generated severe nausea using subsonics (subsonic or infrasonic noise is defined as any sound whose frequency is less than 20 Hz, like Barry White's voice).

    The human body does not react well to extremely low frequency noises: Certain low frequencies can cause sickness, balance problems and discomfort and pain to soft tissues and organs. At higher energy levels, a subsonic shock wave is powerful enough to do damage.

    You are talking about subsonic shockwave devices as soon, as a super amplified tone comes under 20 Hz the soundwaves become shock waves and can be really nasty
    This is about sound cancelation , instantly supressing the sinus patern of the sound by puting exactly the same sinus patern in oposite of this so they cancel eachother out .

    You can do a simple experiment to prove this principle
    Switch your stereo to mono play a song with much bass , then switch the polarity of one speaker and you will notice that the bass sounds different and less present..
    This is caused by the difference in movement of the speaker cones , one moves out with the tone and the other moves in this will not calcel it out but will influence the quality of the sound

    This is called anti sound , this is tested in industrial projects to reduce industrial noise..
    So far the sytems were not powerful and fast enough enough to generate this oposite sinus patern in the sound , but now these two Japanese gentlemen got it working ..

    Point it at someone talking, and his/her voice will be canceled out immediately , the perfect way do silence voices of protest ..

    I have experienced something close to this when talking on Skype and the sound on the other end is bouncing through a computer which is using a laptop and no headphones so that the sound I send is returned with a slight delay.

    For some reason this really grates on my nerves.

    I think Bose also uses a flavor of this to cancel noise outside of the listener so that they can relax in peace.

    The speech canceling could be a very Orwellian power if used to silence a protest.
    Puts a new twist on "silencing the opposition."

    The delay you mention is caused by the "translating" of your analog voice to a digital code that at the other end is "translated back" to analog audio, when you both use headphones you will never notice this , but it if the other has the sound on speakers, this will be picked up by the microphone and your own voice will be returned to you with a really annoying delay
    The other side will not notice this because your headset will seperate the outgoing and incoming sound ..
    When you ensist in using the speakers this can only be canceled out by lowering the sound volume of the speakers to a level that the micophone cannot pick up..

    Both sides using a headset and not the speakers will solve this problem ...

    In the past this delay was about 2 seconds but the translate time is getting shorter with the advancement of new computers..

    Well this is one I had to pick a choice to speak. I see no advantage for this. After all what good is it? Does it have any practical use other than to shut some one up? Personally until there is some practical use for this I think it is just another silly piece of technology.
