2019.01.04

The ultrasound advances like a wave, and when it encounters an obstacle, it is reflected back and passed to the bat's ear. The bat immediately changes the direction of the flight. After years of research and evolution, ultrasound has played a greater role in human use. Ultrasonic radar ranging has long been widely used in life.
