    Anyone have any info on the aircraft sound detectors used by the Soviets as to ranges and who exactly had them? Thanks

    ZT-5
    1938


    ZT-2 stations, 1936

    Also ProzhZvuk-4 stations were used (synchronized searchlight + sound detector)

    As for its abilities ZT-5 could detect targets up to 9 km with +-3 deg. angle error.

      Weren't those used for counter-battery fire?
      I heard that's what the better Artillery Divisions used them for.

        Great pics! But who had these for use in "41. My understanding is that these units picked up the Luftewaffe bombers approaching the Crimea on the 22nd of June, '41.

          For the counter-battery fire were used some kind of similar equipment, but can't say which exactly

            In Leningrad a dozen of blind people were employed as operators of these devices, according to several articles I've read. People with impaired vision often develop a very sharp sense of hearing in compensation, and it was reported they could even tell the type and number of enemy planes approaching the city at long distances. I haven't seen any exact measurements or other statistical data, though.

            Here's one of the articles: http://translate.google.com/translat...hp%3Fid%3D5302

                What does one hear? Is it just like human ear but just further?

                  You could hear the drone of aircraft engines at a greater distance than the unaided ear.

                  Also the horns capture sound from a narrow direction. You can adjust azimuth and elevation until the sound came through the loudest. With several units spaced a good distance apart doing this, you can get a fix on the location and altitude of the incoming aircraft.
