    Whisper mirror
    The whisper mirror is for young and old to try out.

      "The whispering mirror is used for sound transmission and thus enables communication between two people over a greater distance, where the mirror-to-mirror distance is 90 m, with no electrical amplification of the sound signal being used.

      functionality
      The whispering mirror system consists of 2 parallel parabolic mirrors. These serve as both transmitters and receivers. Sound is bundled and radiated head-on by the mirror.
      This "sonic beam" is then captured by the opposite mirror and again focused at its focus. The higher the frequency of the sound, the better this effect works.
      Low frequencies can not be bundled so well, so a transmitted normal voice sounds distorted, while higher-frequency whisper sounds are transmitted better.


      operation manual
      In order to use the call transfer, the sound to be transmitted must be generated face to mirror in the focus of one mirror and received in the focus of the mirror on the other side. The focal point is about 90 cm away from the center of the mirror. The more accurate the speaker is in this point, the better the transmission effect. You can also use your ear to search for the place where you hear the best, while the other person is talking or making another sound. This position is then best suited to speaking in. "
