Therapeutic Ultrasound Therapeutic ultrasound is in the frequency range of about 0.8-3.0 MHz. The waves are generated by a piezoelectric effect caused by the vibration of crystals within the head of the wand/probe. The sound waves that pass through the skin cause a vibration of the local tissues.

What you cannot hear CAN affect you. What you cannot hear CAN affect you. The American Wind Energy Association state that a scientific panel they sponsored concluded that : “ Subaudible, low frequency sound and infrasound from wind turbines do not present a risk to human health.”.t is also known that OHC provide mechanical amplification of the high frequency sounds that you normally hear. The presence of low frequency sound can alter the amplification of high frequency sounds which causes amplitude modulation and harmonic distortion of the high frequency sounds.

- Ultrasound is sound waves with frequencies which are higher than those audible to humans. Ultrasonic images also known as sonograms are made by sending pulses of ultrasound into tissue using a probe. The sound echoes off the tissue; with different tissues reflecting varying degrees of sound. These echoes are recorded and displayed as an image to the operator.

What is an ultrasound? An ultrasound scan is a medical test that uses high-frequency sound waves to capture live images from the inside of your body. The technology is similar to that used by sonar and radar, which help the military detect planes and ships. An ultrasound allows your doctor to see problems with organs, vessels, and tissues—without needing to make an incision. Unlike other imaging techniques, ultrasound uses no radiation, so it is the preferred method for viewing a developing fetus during pregnancy.

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.

General Ultrasound Ultrasound is safe and painless, and produces pictures of the inside of the body using sound waves. Ultrasound imaging, also called ultrasound scanning or sonography, involves the use of a small transducer (probe) and ultrasound gel placed directly on the skin.High-frequency sound waves are transmitted from the probe through the gel into the body.ltrasound imaging is a noninvasive medical test that helps physicians diagnose and treat medical conditions. Conventional ultrasound displays the images in thin, flat sections of the body. Advancements in ultrasound technology include three-dimensional (3-D) ultrasound that formats the sound wave data into 3-D images.

- ULTRASOUND. FIND OUT MORE. Sound can be low-pitched, like the rumble of a large truck, or high-pitched, like a whistle. The pitch of a sound depends on the frequency of its wave. Piano keys produce notes that increase in pitch from the left side of the keyboard to the right. We can hear sounds of different pitches, but there are some sounds we cannot hear. Our ears cannot detect very low-pitched noises, known as infrasound, or very high-pitched noises, called ULTRASOUND.

Ultrasound Summary. Ultrasound is a type of imaging. It uses high-frequency sound waves to look at organs and structures inside the body. Health care professionals use it to view the heart, blood vessels, kidneys, liver, and other organs. During pregnancy, doctors use ultrasound to view the fetus.

Ultrasound Examination in Cats An ultrasound machine emits and receives high frequency ultrasound waves through a transducer or probe. The probe is placed over the area of interest, directing the sound waves into the body. The ultrasound waves may be transmitted through, reflected from, or absorbed by the tissues that they encounter.

- Medical ultrasound is a diagnostic imaging technique based on the application of ultrasound. It is used to see internal body structures such as tendons, muscles, joints,blood vessels and internal organs. Its aim is often to find a source of a disease or to exclude any pathology. The practice of examining pregnant women using ultrasound is called obstetric ultrasound, and is widely used. Ultrasound is sound waves with frequencies which are higher than those audible to humans.

- Gunshots are around 140Db, and can cause instant pain as well as damage. Higher overpressure gradiants (bigger noises) can of course do even more.   Really loud noises, like a gunshot at close range, can cause deafness, ringing in your ears (tinnitis), and may actually damage the ear drum.

- 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.

- Ultrasound - Higher tier. Ultrasound may be used instead of x-rays for certain scans, such as scan of unborn babies. Compared to x-ray photographs, ultrasound scans: Do not damage living cells; Produce images of soft tissue; Medical images from ultrasound. Ultrasound is sent into the patient's body. Some of the ultrasound is reflected at each boundary between different tissues or organs. The depth of each layer is calculated using the time taken for each reflected wave to return.
