MONSTER EAR TRUMPETS FOR AIR DEFENSE

During the last years of the Great War, sound detectors played an increasingly important part in the air defenses
of all the belligerents.
Since those days they have undergone great development.
Here the emperor of Japan is inspecting the huge trumpet-like detectors
that work in conjunction with the anti-aircraft guns (seen right)

I think that was WW I too early for a WW II photo

Hey tubbs, great to see you. Happy New Year lol

Here is what I found...

In the early 1900s, Japan’s military adopted acoustic location, using iconic “war tubas” in order to locate aircrafts and submarines.

According to Spoon-Tamago, these massive acoustic locators were used to detect incoming aircraft before the invention of radar. Japanese soldiers picked up the sound of far-away planes by connecting the large horns – one on a horizontal axis and the other on a vertical axis – to their ears and listening for the sound waves emitted by early 20th-century aircraft. Some smaller versions of the device were also stationed to the ground on a tripod.

Though war tubas didn’t last long – they were made redundant once radar came into the picture – the sight of Japanese soldiers operating them is a bizarre one.

Have a peek at these giant brass instruments, courtesy of Spoon-Tamago, below:

Yes JDI, WW2 was from 1939-1945


lol....Thank you Dee.....I know that.....this was a feeble attempt at sarcasm....I post a lot of stuff and I try to make sure that it is accurate but there is always someone who can't wait to point out that this is not true, or photo shopped or not real etc. In lot of cases one can google and verfiy if this is accurate or not.....not sure if it is necessary to try point it out......In this case I provided a link to where I got the info from....Most of the time I will accept this BS and not bother to reply but occasionally it ticks me off....... If I had the reputation of posting a lot of crap I could understand someone trying to call me on this but I don't belief this is the case......and yes I will post something and later find out that it is not accurate......
