    The principle of ultrasonic ranging
    The sound wave frequency that human ears can hear is 20HZ～20KHz. When the frequency is higher than 20KHz, the human ear cannot hear it. Therefore, we call the sound wave with a frequency higher than 20KHz "ultrasonic wave".Ultrasound has a strong directivity and travels a long distance in the air.
