- An ultrasound scan, also referred to as a sonogram, diagnostic sonography, and ultrasonography, is a device that uses high frequency sound waves to create an image of some part of the inside of the body, such as the stomach, liver, heart, tendons, muscles, joints and blood vessels.ltrasound is used to create images of the fetus or embryo in the uterus. Today, often referred to simply as an ultrasound scan, it is part of standard prenatal care.

hypersonic Today's experimental scramjets are not merely supersonic - meaning they fly faster than the speed of sound, or Mach 1 - but hypersonic, meaning they fly at Mach 5 or faster. Space News From SpaceDaily.Com. The military might need a hypersonic weapon that would travel in the exoatmosphere to take out a limited number of fleeting targets, he said.

Ultrasound and Insects Small mammals like Dogs, Cats etc. responds to 22-25 kHz US and Rats to 60-72 kHz. Insects like Mosquitoes, Flies responds to 38-44 kHz. What is Ultrasound? The hearing property of human ear is limited. Human ear can perceive sound with in a frequency range of 20 Hz to 20 kHz. The sound frequency below 20 Hz is Infrasonic sound and above 20 kHz is Ultrasonic sound. Human ear is not sensitive to US because the eardrum cannot vibrate as fast as US. Ultrasound has high frequency, so the wave is very powerful.

Ultrasonic Sound Ultrasonic sound can be produced by transducers which operate either by the piezoelectric effect or the magnetostrictive effect. The magnetostrictive transducers can be used to produce high intensity ultrasonic sound in the 20-40 kHz range for ultrasonic cleaning and other mechanical applications.Ultrasonic medical imaging typically uses much higher ultrasound frequencies in the range 1-20 MHz.he magnetostrictive transducers can be used to produce high intensity ultrasonic sound in the 20-40 kHz range for ultrasonic cleaning and other mechanical applications.

- Ultrasound Definition. Ultrasound is cyclic mechanical vibration with a frequency greater than the upper limit of human hearing, which is approximately 25 kilohertz (25,000 hertz) in healthy, young adults. A vibration source in a mechanical medium will cause wave propagation. Ultrasound is a mechanical wave, cannot exist in vacuum.

How Ultrasonics Work Ultrasonic system power is rated in how much energy, in watts, is generated in the ultrasonic tank. Higher power systems generally mean shorter part immersion times in the fluid. The ideal cleaning frequency is determined by the size of dirt being cleaned.

Whatâs faster than supersonic? Hypersonic, of course Travel becomes hypersonic when temperatures get so hot that the air molecules become unstable and start losing electrons. At low temperatures, the air is made up of oxygen and nitrogen electrons, but at hypersonic speed, the air begins to change chemically and becomes an electrically-charged field.

Ultrasonics - How Ultrasonic Waves Are Generated, Ultrasonic Dispersion, Ultrasonic Cleaning, Welding, Nondestructive Testing, Scientific Research - Applications, Coagulation, Humidification, Milk homogenization and pasteurization, Drilling, Soldering, El sound khz ultrasound frequencies. Ultrasonics or ultrasound, derived from the Latin words ultra, meaning beyond, and sonic, meaning sound, is a term used to describe sound waves that vibrate more rapidly than the human ear can detect. Sound waves travel as concentric hollow spheres.

- By adjusting the power and frequency of an ultrasonic system to the level where it cleans the part without eroding the part you can avoid damage to the part. The higher the frequency, the more evenly spread out the power. This produces more even cleaning on the part.

- Aerodynamics, from Greek ἀήρ aer (air) + δυναμική (dynamics), is a branch of Fluid dynamics concerned with studying the motion of air, particularly when it interacts with a solid object, such as an airplane wing.n aerodynamics, hypersonic speeds are speeds that are highly supersonic. In the 1970s, the term generally came to refer to speeds of Mach 5 (5 times the speed of sound) and above. The hypersonic regime is a subset of the supersonic regime.
