I came across this weird photo today and I'm at a total loss to explain it.
Has anyone seen this before?

Listening devices... Sort of a low-tech means of detecting incoming airplanes before radar was invented.
Joe's dead right; here's a linky to these Japanese sound amplifiers.

Thanks, guys! A remember seeing this same image a few years ago and asking the same question as Glen.
Ah Ned beat me to it.
This sort of thing was seen in europe too, if I'm not mistaken, although in a different form.

The concrete acoustic mirror would have a man sat in front of it with a similar rig to these horns. Used up to the advent of radar, and no doubt after to compliment the new technology. Surprisingly effective too if I remember a documentary on it.
I was a Fire Control Technician in my U.S. Navy days and worked on a surface to air missile system and the radar. What a cool device and a fantastic example of technology at the time. I had no idea this ever existed
Thanks
