Obsolete Military Designs for Magnifying Sound

By Rain Noe - July 26, 2011

A few years ago we posted about these beautiful parabolic structures made of concrete, as a way to magnify sound in the days of World War I. The British used them to listen for incoming enemy fighters in an era that antedated radar.

What we didn't realize was that there were smaller, more experimental versions as well. We've just stumbled across a cache of photos showing the crazy constructions people made in efforts to bring faraway sound into a listener's ears.

There's actually one of these located on the Fort Point channel in Boston, right by the Gillette World Headquarters.
