| Mounting | Because of their shape the noise emitted by the Air horns is very directional. Therefore it is most important that Air horns are pointed in the direction where the sound is intended to be heard. Horns should be mounted well above ground level and at least 3 meters clear of all obstruction that could deflect the sound. For transport applications they should be mounted as high as practically possible, pointing in the direction of travel. | |||
