–Acoustic warning devices for track vehicles–

Requirements for signal horns with which the required audibility of approaching track vehicles including high speed and conventional train systems is met

  • Sound pressure level: 101 – 125 dB(C) in 25m
    129 – 136 dB(C) in 1m
  • Frequency (§5.2.1): different frequencies possible
  • Protection of outside influences (§5.5):
    –Signal horns should be protected against the collision with objects present in the air (splinters, dust, birds). For this we offer protective grids and protective nets.
