Ultrasound has high utilization value

date:[2012-06-05]     pk_hits:

Ultrasound is a sound wave with a frequency higher than 20000 hertz. It has good directionality, strong penetration ability, and is easy to obtain concentrated sound energy. It can travel a long distance in water and can be used for ranging, speed measurement, cleaning, welding, crushing, sterilization, and disinfection. There are many applications in medicine, military, industry, and agriculture. Ultrasound is named after its lower frequency limit, which is approximately equal to the upper limit of human hearing.

The enormous energy of ultrasound can also cause the stones in the human body to undergo intense forced vibration and shatter, thereby alleviating pain and achieving the goal of cure. Ultrasound is widely used in medicine, such as color ultrasound, B-ultrasound, and lithotripsy (such as removing eye bags from gallstones and kidney stones), which can also destroy bacterial structures and sterilize items.
