Whistle structures

[Category : - Automotive Accessories ]
[Viewed 74 times]

Devices that emit sound audible to nearby animals can include a deflection structure or other support structure and, connected to it, at least one whistle structure. The deflection structure can, for example, be a rain guard, an insect deflector, or a rock deflector. It can, for example, have an air flow surface across which air flows when the vehicle on which it is mounted moves at normal operating speeds, and whistle structures can be activated by the air flow.

By increasing the air flow to the whistle, the sound emitted is stronger and can be heard by animals who are close to roadways. The animals will be less likely tomato proceed onto highway if they hear the strong whistle “alert”.
