"Ultrasonic" means higher frequency than humans can hear.
Therefore, you can't hear it.
Frequency too high for human ears.
Dogs, cats, and bats can hear it if it's not toohigh.
Short wavelength makes it good for imaging without radiation.
Pictures made with ultrasonic sound are called "ultrasound" images.

What are the frequencies that are considered ultrasonic sounds?
Anything above 20 KHz is, although the medical ultrasound systems operate with sounds up into the megahertz.
Does sound rise up?
Not entirely sure what you mean with "sound go up"; if the amplitude goes up, you will perceive the sound as louder.
What are three ways that ultrasonic waves can be used in medicine?
Observation (sonogram), Treatment (breaking up solid stones [gall bladder or kidney]). Cleaning such things as false teeth.
What sre sound waves?
Sound waves are longitudinal vibrations through matter that ears can pick up as sound.
Why would a car alarm sound for no apparent reason?
The most likely cause. The ultrasonic sensors have picked up air movement in the cars interior.
Why are ultrasonic sound waves used for finding range and direction?
hold your roast beef up in the wind and see which way it blows. use gray too for legit results
Is ultra sonic sound harmful to your ears?
People's ears acceptable to sound range from 16 to 20,000 Hertz. When the sound of frequency reached 25 to 8,200 Hertz, can feel the vibration. Less than 16 hz voice called bass, higher than 20,000 Hertz for ultrasonic. More than 20 years ago, scientists began to earnest study voice to the influence of human body, the results showed that the ultrasonic to internal organs of harmful effects. Elastic joints and electric guitar hand fingers damage Originally, long-term exposure to more than 20,000 Hertz voice effect, can cause human body organization a slight fever. When frequency high to ultrasonic or higher, fever rapidly. The results, the body of water molecules are burned, the surrounding tissue destruction. Ultrasonic if not controlled more dangerous, can cause excessive blood, inflammation and arthritis. High frequency instrument, such as electric guitar, in performing sent lot of ultrasonic. So, a musician's hand joints and finger damage. Because have clothes, the body suffers smaller. Sometimes the electric guitar on bending the knees, also can affect the knee. The high strength of high-power ultrasonic continuing role in human tissue is harmful. Small power ultrasound in intermittent role in human tissue is very beneficial. Ultrasonic is a kind of vibration wave. Tell a popular example, when someone gives you gently beat back you comfortable, but when you feel pain crit, you even damage. The following originates from the network reference No harm to people, ultrasonic there is profit. Actually acoustic belongs to the category of voice, belong to wave, sound waves refers to the human ear can feel a kind of wave, the frequency range for 16Hz - 20KHz. When sound waves of frequency 16Hz when he called below 20KHz is called device, higher than the ultrasonic sound wave. Ultrasonic has the following features: 1) ultrasonic available in gas, liquid and solid, solid melts in the media such as efficient human-to-human transmission. 2) ultrasonic can transfer strong energy. 3) ultrasonic produces reflection, interference, stacked and resonance phenomenon. 4) ultrasonic in liquid medium transmission, the screen produces strong impact and the cavitation phenomenon. Ultrasonic sound is a member of the family. Sound waves are objects mechanical vibration condition (or energy) form of transmission of. So-called vibration refers to material of particles in its balance position near the round-trip movement. For example, reaches the knock that it up and down, the vibration state vibration through the air medium in all directions, this would be sound waves spread. Ultrasonic vibration frequency than 20KHz refers to the above, the person is in natural environment to hear and feel of the sound wave. Ultrasonic treatment concept: Ultrasound treatment learning is an important part of ultrasonography. Ultrasound treatment will ultrasonic energy function in the human body the lesion site, in order to achieve treat diseases and stimulative airframe rehabilitation purpose. Around the world, ultrasonic diagnostics, widely used in the treatment of science, engineering, biology, etc. The composer household ultrasonic constrution belongs to the ultrasonic therapeudic use category. (a) in engineering application: underwater positioning and communications, underground resources exploration, etc (2) biological applications: shear macromolecules, bioengineering and handle seed, etc (3) diagnostics applications: type A, type B, type, type D, M type double function, and sufficiency, etc (4) therapeutic applications: physical, cancer, surgery, in vitro gravel, dental, etc Ultrasonic features: 1, ultrasonic in spreading, directional, strong energy to concentrate. 2, ultrasonic can spread in different medium, and can spread far enough distance. 3, ultrasonic and sound transmission medium interaction moderate, easy for carrying about sound transmission medium state information (diagnosis or sound transmission medium to produce effect (treatment). Ultrasonic is a kind of wave form, it can be used as a detection and load information carrier or medium (such as type-b ultrasonic diagnosis); used as Ultrasonic also an energy form, when its strength over a certain value, it can be spread through the medium of ultrasonic and interaction, to influence the result that break the latter, change of state, nature and structure (as a treatment for). Ultrasonic history: A, international aspects: Since the late 19th and early 20th centuries, in the physics discovered on the piezoelectric effect and reverse piezoelectric effect later, people solved the use of electronics technology producing ultrasonic method, from now on rapid development and promotion unveiled the ultrasonic technology history chapter.
What are the uses of ultrasonic sound waves?
With special electronically driven crystals, it is possible to produce mechanical waves at any frequency up to a few million Hertz (cycles per second). If the sound waves are above 20kHz (the maximum humanly audible frequency) they are called ultrasonic waves. Because of their short wavelength, ultrasonic waves can be focused onto small areas and can be imaged much as visible light. Ultrasonic waves penetrate tissue and are scattered and absorbed within it. Using specialized techniques called ultrasound imaging, it is possible to form visible images of ultrasonic reflections and absorptions. Therefore, structures within living organisms can be examined with ultrasound, as with X-rays. Ultrasonic examinations are safer than X-rays and often can provide as much information. In some cases, such as in the examination of a fetus and the heart, ultrasonic methods can show motion, which is very useful in such displays.Here are a few:Ultrasonic cleaningUltrasonic motion detectionUltrasonic weldingUltrasonic sonographyUltrasonic communicationUltrasonic destructionHeart examsPre-natal investigation
Does sound travel everywhere?
Yes sound do travel anywhere so if you have projects, essays, homework assignment, write it up: Yes, sound do travel anywhere :)
What is a short write-up?
A short write-up is a brief and succinct piece of writing that conveys information or summarizes a topic in a concise manner. It typically captures the main points or key ideas without going into extensive detail.
What is a good thesis for a compare and contrast essay about basketball and football?
You're going about it backwards -- the thesis is a brief statement of what you're going to write about. Only you can come up with something you want to write about. Write the essay first, then your thesis will come to you from what you wrote.
How do you write the sound that a pissed cat makes?
Angry cats growl and hiss. You can write "Rrrrrr" or "hiss" or make up your own way of sounding out the noise.
Is there such thing as sensors that pick up ultrasonic frequencies?
Yes there is. They're commonly known as sonar sensors. Sonar sensors are usually a coupled device which emitt and receive high frequency sound waves and can be used to detect objects within a close proximity.
What to include in a write up in what you did in your evaluation?
In a write-up about your evaluation, you should include a concise introduction to the purpose of the evaluation, a brief description of the methodology used, key findings, and any recommendations or action plans resulting from the evaluation. Be sure to highlight the significance of the evaluation in informing decision-making or improvements.
Which treatment for cataracts uses ultrasonic waves to disintegrate cloudy lenses?
Phacoemulsification is the type of cataract removal in which high intensity sound waves are used to break up the clouded lens, which is removed through a small "tunnel," and the new lens is inserted through the same "tunnel."
