The frequency set would also determine who would hear the sound - If set to sonic, it would be heard by birds and humans, but at ultrasonic, it would be heard only by the birds. This product is outstanding, with adjustable arms reaching up to a 1.5-meter diameter. These arms are constantly spinning with the power of solar energy.
