Speech-Jamming Gun Silences From 30 Meters

Japanese researchers have created a hand-held gun that can jam the words of speakers who are more than 30 meters (100ft) away. The gun has two purposes, according to the researchers: At its most basic, this gun could be used in libraries and other quiet spaces to stop people from speaking — but its second application is a lot more chilling. The researchers were looking for a way to stop 'louder, stronger' voices from saying more than their fair share in conversation. The paper reads: 'We have to establish and obey rules for proper turn-taking when speaking. However, some people tend to lengthen their turns or deliberately interrupt other people when it is their turn in order to establish their presence rather than achieve more fruitful discussions. Furthermore, some people tend to jeer at speakers to invalidate their speech.' In other words, this speech-jamming gun was built to enforce 'proper' conversations."

The gun works by listening in with a directional microphone, and then, after a short delay of around 0.2 seconds, playing it back with a directional speaker. This triggers an effect that psychologists call Delayed Auditory Feedback (DAF), which has long been known to interrupt your speech (you might’ve experienced the same effect if you’ve ever heard your own voice echoing through Skype or another voice comms program). According to the researchers, DAF doesn’t cause physical discomfort, but the fact that you’re unable to talk is obviously quite stressful.

Well, actually, that’s a lie: Apparently DAF doesn’t work with utterances like “ahhh!†or “boooo!†or other non-wordy constructs. So, basically, we’d all be reduced to communicating with grunts and gestures.

Interesting..!
 
Should issue a couple(of hundered(?)) of these for our Assembly sessions. And a few dozen tranq guns for safe measure against the 'booing'.
 
Should be used in Indian parliament to shut up those shouting idiots

same principle used in noise cancelling headphones i think.

after going to such lengths, they can go one step ahead and just use a taser on the guy or loudmouth, and make them unconscious. /s

Added to that, the device should also send out the following in her direction, at regular intervals:

"Uh-huh", "Hmm", "Really?", "Yes dear", "You are correct", "You don't say?!", "Sure thing", "Definitely"
 
Maybe we can try it out on Being.Smart when / if we end up having a freak encounter with him.
