Speech Jammer

The usual disclaimer: Did a search on Arrse but did not find a thread about this:

Japanese Speech Jammer Can Silence Hecklers, But Is It Ethical? | Sci-Tech Today
The prototype speech jammer looks like a radar gun used by police to trap speeders, but with a laser pointer, directional microphone and a distance sensor. The speech jammer is effective within about 98 feet. Its inventors suggest the speech jammer could be used to block hecklers or microphone hogs at events, or people who are nuisances in public.
This sounds like great fun - a shame they can't make one for the telephone to cut off salesmen in their tracks.

The possibilities are mind boggling. French gobshite in my local last night deserved a burst of rapid from that little Jap machine.

I find this works much better...


it allows for a scalable response too.

It's designed to stop heckling is it? Well supposing someone in the audience has one too - eh?

I reckon that Dale would talk too it for so long that it would commit electrical suicide.

From the description of how that works, surely a pair a of ear plugs stops it dead?
Earplugs would prevent you from delivering your witty, razor-sharp heckle at the correct moment. You don't want to be calling out when everyone else is clapping.

What if you were using a specially designed head set?

You put the microphone on the lap of the person 3 seats to your left/right. this feeds ambient noise in to your own speakers, so when you deliver your heckle at the correct moment, the 'feed back' from this device doesn't affect you?

For added protection, the headset could be fitted with a microphone reverse connected to a speaker, so that the device itself was met with a reversed soundwave version of what you had said... no idea what it would do. But let's find out.

I like your think there CF. Although on the other hand, why not just chuck a large soggy root vegetable at the podium? - let's see how the Nips deal with that.

Judging by the fact it's parked on a film set it's probably a prop...

this isn't though...

The Active Denial System (ADS) is a non-lethal, directed-energy weapon developed by the U.S. military.[SUP][1][/SUP] It is a strong millimeter-wave transmitter primarily used for crowd control (the "goodbye effect"[SUP][2][/SUP]). Some ADS such as HPEM ADS are also used to disable vehicles.[SUP][3][/SUP] Informally, the weapon is also called the heat ray.[SUP][4][/SUP] Raytheon is currently marketing a reduced-range version of this technology.[SUP][5][/SUP] The ADS was deployed in 2010 with the United States military in the Afghanistan War, but was withdrawn without seeing combat.[SUP][6][/SUP] On August 20, 2010 the Los Angeles Sheriff's Department announced its intent to use this technology on prisoners in the Pitchess Detention Center in Los Angeles, stating its intent to use it in "operational evaluation" in situations such as breaking up prisoner fights.[SUP][7][/SUP]

The ADS works by firing a high-powered beam of electromagnetic radiation in the form of high-frequency millimeter waves at 95 GHz[SUP][8][/SUP] (a wavelength of 3.2 mm). Similar to the same way that a microwave oven heats food, the millimeter waves excite the water and fat molecules in the body, instantly heating it and causing intense pain.

This guy looks a little concerned about it.

Looks more like an LRAD, but I may be wrong.
