American troops using a newly-developed acoustic locator, mounted on a wheeled platform. The large horns amplified distant sounds, monitored through headphones worn by a crew member, who could direct the platform to move and pinpoint distant enemy aircraft. Development of passive acoustic location accelerated during World War I, later surpassed by the development of radar in the 1940s. (National Archives)

Amazing. I wonder how loud it was in the armored train car with the 19 machine guns. (!)

Not written, but needed background.
Many of these were for detecting and tracking the dirigibles slowly moving over England from Germany dropping bombs at night. Pre-radar, they were trying to locate the engine noise to shoot back.
WWII? These were tried again, since radar wasn’t real accurate in elevation nor direction early in the war. Not real successful, but better than nothing since planes were many times faster, higher, more numerous.
