Jericho Trumpet
As Jericho trumpet and Jericho device were sirens indicated that by the middle of World War II to the legs of the German dive bombers of the type Junkers Ju 87 were installed. These sirens were operated by the airstream via small propellers as soon as the aircraft went into the very fast and steep dive. They served to intimidate the enemy and were part of the psychological warfare . The inventor of the Jericho trumpet was Ernst Udet .
The name of these sirens is derived from the case of Jerichos mentioned in the Bible , in which the sound of "trumpets" or "trumpets" (Hebrew qeren hayovel , "ram's horn", meaning Shofar ) is said to have brought the city walls to collapse ( Jos 6 , 5 EU ).
Even today, the misconception is widespread that crashing or crashing planes produce these typical siren noises. Some film scenes in which planes (crash) are accompanied by acoustics. It is even used with helicopters or slowly spinning machines. Some air show viewers mistake the siren sound for the engine noises that occur in a steep dive. The fact that the airplane accelerates in a nosedive due to the gravitational pull alone and the airflow is now much higher, the airplane engine over-revs quite easily, which then sounds similar to the noises that Jericho trumpets produce. However, the engine noises are much quieter.
There were also similar devices that were attached to the tail fins of the bombs and also served to increase the psychological effect on the attacked persons. However, these were not sirens with propellers, but much simpler pipes, similar to a short organ pipe .
music
The final chords of In the Flesh? from Pink Floyd are overlaid by this noise and lead over to vocalizations of an infant.
