Sound wave transmitter for driving animals off the road or railway

摘要

The transmitter transmits sound waves at frequencies outside the range of human hearing and detectable by different types of animals in a position to be on the road or track. It transmits different frequencies within a defined frequency range. It can be manually activated or automatically after defined switch-on conditions are fulfilled. When integrated into a vehicle, the amplification of the transmitter's transmitted sound waves can be increased with increasing speed of travel.
