Now this little invention seen above gives new meaning to the term "shut the f@ck up already!!" Two Japanese researchers recently introduced a prototype for a device they call a SpeechJammer that can literally “jam” someone’s voice — effectively stopping them from talking. Now they’ve released a video of the device in action.
Yup, you read that right these guys have potentially invented a literal "conversation ender". Kazutaka Kurihara and Koji Tsukada the apparent researchers responsible released a video of how the device works after their PDF went viral on Thursday. Kurihara, a research assistant at the National Institute of Advanced Industrial Science and Technology in Tsukada & Tsukada, an assistant professor at Ochanomizu University in Tokyo were apparently surprised of the leak.
Check out the video,
Yeah, so the design of the SpeechJammer is deceptively simple. It consists of a direction-sensitive microphone and a direction-sensitive speaker, a motherboard, a distance sensor and some relatively straightforward code. The concept is simple, too — it operates on the well-studied principle of delayed auditory feedback. By playing someone’s voice back to them, at a slight delay (around 200 milliseconds), you can jam a person’s speech.
Its true sonic devices have made more than one appearance in pop culture in the past. Sci-fi author J.G. Ballard in fact wrote a short story called, “The Sound-Sweep”. The story was published in 1960and depicted a vacuum cleaner like device called a “sonovac” that sweeps up the debris of old sounds. The evil genius German composer, Karlheinz Stockhausen had plans for a “sound swallower,” which would cancel unwanted sounds in the environment using the acoustic principle of destructive interference. And in 1984 German film Decoder, proposed special yellow cassette tapes that could play “anti-Muzak” that destroys the lulling tones of Muzak, stimulating diners at a fast-food restaurant to throw up en masse and start rioting (f@cking Germans, man!!)
But instead of sci-fi, terrifying, terrifying sci-fi, the Japanese researchers behind the SpeechJammer were inspired by medical devices designed to help people with speech problems when conceiving their STFU gun. Delayed auditory feedback, or DAF, devices have been used to help stutterers for decades. Turns out if a stutterer hears his own voice at a slight delay, stuttering often improves. But if a non-stutterer uses a DAF device designed to help stutterers, he can start stuttering — and the effect is more pronounced if the delay is longer, up to a certain point. Ultimately hearing your own voice if you don't already stutter will confuse the shit out of you so much it can cause you to shut the f@ck up and listen for a change, asshole.
“We utilized DAF to develop a device that can jam remote physically unimpaired people’s speech whether they want it or not,” write the researchers. “[The] device possesses one characteristic that is different from the usual medical DAF device; namely, the microphone and speaker are located distant from the target.”
The gun has a range of up to several feet. So those jerks arguing in the apartment next door? Pow, STFU!! The asshole on the bus having the loudest private conversation on your iphone 4S? Take notice 'cause I will silence your shit boy-eeee.!!The device also has diabolical and criminal applications as well but i'll let you use your imagination as to what those could be, evil bastards. For now though The Speech Jammer remains merely a prototype.
