Please Ident this contraption!

Hello Everyone,

Can anyone provide any information at all on this listening device, It would
be greatly appreciated. Thank You!

 

Looks like a torture device ! I have no idea. Do you happen to know what country it is from ?

 

Before the advent of radar, in the inter-war years there was fairly widespread experimentation with 'listening devices' to give early warning of bombers. I'd say that this is almost certainly one of them, but I'm not sure which Country.....

 

Must have had some intensive wear, like listening to the entire 8th Air Force all at the same time

This one apparently is Czech... Acoustic Radar.

How Were World War II Searchlights Used?

 

That's a great site Za ! They look like works of art. I really like the Japanese sound device.

Martin, do you know if the ones in Kent are still there ?

 

Civilians got in on the act to, as did the medical profession. This one is called a hand made stethoscope.

and you thought you had big ears?

 

Holy smoke, SW

What I found interesting in the articlaes above was that sound location was indeed used as precursors to searchlights, before radar became developed and inexpensive enough.

 

Wow, that is some weird looking stuff! That technology has sure come a long way!!

 

Thats made my day, seeing that thing!
I can imagine that that guy is trying hard to keep a straight face, especially with all the other people giggling at him.

 

aaah! ya beat me to it! I loved the japanese versions of this that looked like huge tubas! hilarious!

 

Excellent. Considering one arm is oriented towards the ground does that mean they suspected an underground attack ?

 

Far too garish and overstated for daily wear.... IMHO....a formal occasion, possibly.... a reception, a wedding or Mardi Gras.... certainly....

...but for daily 'Grab something out of the closet and go to the supermarket', I MUCH prefer something more along the lines of Skunk Works' stylish, understated yet distinctly original head gear....





... I'm just absolutely green with envy!

Well, mine is so.... so..... 'last week'.....



..... I'm almost embarrassed to be seen in public!

The kent sound detectors are still there, at the side of a gravel quarry/lake..... I think they may have even been given listed building status...........

 

I saw some of these in a Finnish anti-air-museum, it was the first time i ever heard of these.

How could anybody hear a bomber coming with those, there must be so much distraction like animals, wind, friends shouting into the big horns, etc.

But they must´ve worked, if they were so widespread.

 

They're directional, they amplify sound from a narrow cone, so unless your sparrow is chirping inside that listening envelope you won't hear it.

Tweet, tweet.

 

(... as Za sneaks up with a hand-held airhorn...)

I was reading through those two fascinating links that Za posted and was interested to read that acoustic locaters were deployed well into World War II in order to deceive the Germans and hide the fact that the Allies were, in fact, using radar.
