Where [solar ultrasonic bird price of the manufacturers] where [solar ultrasonic bird price of the manufacturers] where [solar ultrasonic bird price because the manufacturers] ultrasonic bird is mainly used for electric power, irrigation other outdoor venues, so the power supply generally use solar power, power system stability directly affects the bird's life and the effect of ultrasonic bird control using frequency ultrasound to drive away insects, birds belonging to suffer physical methods of governance, insect infestation, etc., totally without reliance on chemical drugs, so non-toxic, odorless, will not cause secondary pollution. Human hearing range is about 16-20000Hz, ultrasonic bird control the output frequency of the ultrasonic generally in more than 20000Hz, 20000Hz for the frequency bands above human auditory system can not generate a response, so we did not hear ears to, and the power of ultrasonic bird failed to meet the body's ability to penetrate, so has no effect on the human body.
