Ultrasound waves are able to penetrate deep into the body and must be very specifically targeted when they are used at very high energy levels to heat and destroy fibroids and tumors. This cannot be heard by humans. The kilohertz (kHz), for example, can be used to measure sound waves vibrating at the rate of 1,000 (kilo means 1,000) times per second, and the unit megahertz (MHZ) stands for a million vibrations per second. A number of animals are capable of emitting ultrasonic frequencies and use. Inside your PT's ultrasound unit is a small crystal. Any frequency of above 20kz is considered ultrasonic [4-6, 8-10]. First of all, ultrasound (ultrasonic ) is high frequency sound waves, between 800,000 Hz and 2,000,000 Hz. This produces an an echogenic "black" image. Ultrasonic A sound wave of a frequency greater than 20,000 Hz, typically above the range of human hearing. During winter months when indoor heating can drive the humidity in your home down to 20 percent or less, an animal-shaped ultrasonic humidifier can go into overtime replacing moisture in the air in a child's room. How does ultrasound repel pests? US pest chasers are designed to repel pests from the home. Bats produce a very high-pitch sound (ultrasonic, beyond the human hearing range). Ultrasound machines make sound waves that are too high for the human ear to hear. The ultrasonic waves vibrate at a tremendous frequency, as high as 46 KHz, and produce a lot of energy. Degassing and defoaming of liquids is an interesting application of ultrasonic devices. Ultrasonic Degassing and Defoaming of Liquids. Ultrasonic technology has been used for multiple cleaning purposes. Bats also determine how big objects are and in which direction they are located. The ultrasonic waves actually crush the hard, calcified tartar deposits, which allows them to be removed from the teeth. Ultrasonic cleaning is a process that uses ultrasound (usually from 20-40 kHz) to agitate a fluid.
