Therefore, we refer to sound waves that are above 20000 Hz as "ultrasound". Because of its good directivity, penetrating ability, easy to obtain a more concentrated sound energy, in the water spread far away, can be used for ranging, speed, cleaning, welding, gravel, sterilization and disinfection.
