From the “building a better mousetrap” category comes the Shout-O-Phone, a souped-up upholstered standard bed version of Professor Mayer’s enhanced ears that boosts the outgoing sound as properly. Awesome… not so substantially the device, but that it took 60 years for it to be developed.

The Ears Have It

Sounds Like War

As Hitler speedily rebuilt Germany’s war machine in salyer upholstered standard the late 1930s, antiaircraft measures have been a high priority. German radar study was far behind developments in Wonderful Britain but that wasn’t the case with acoustic detection, as shown above. Behold, das Ringtrichterrichtungshoerer (or “ring-horn acoustic path detector”)… RRH for short, made use of in the course of the Second Planet war to assist aim searchlights at night-flying bombers.

Release The War Tubas!
