What is an example of ultrasonic?
The definition of ultrasonic, also known as ultrasound, is sound waves that have a higher frequency than the human ear can hear. An example of ultrasonic is an ultrasound image of an unborn baby. An example of ultrasonic is a dog whistle that cannot be heard by humans, See ultrasonic welding and saser.
What is ultrasonic mean in science?
ultrasound waves
ultrasonics, vibrations of frequencies greater than the upper limit of the audible range for humans—that is, greater than about 20 kilohertz. The term sonic is applied to ultrasound waves of very high amplitudes.
What is the word ultrasonic mean?
1 : having a frequency above the human ear’s audibility limit of about 20,000 hertz —used of waves and vibrations. 2 : utilizing, produced by, or relating to ultrasonic waves or vibrations.
What is infrasonic give an example?
Infrasound is sound which extends below the range of human hearing (from 20 Hz down to 0.001 Hz), and it eminates from many natural and man made sources. For example, some animals, such as whales, elephants and giraffes communicate using infrasound over long distances.
What are ultrasounds used for?
Ultrasound imaging uses sound waves to produce pictures of the inside of the body. It helps diagnose the causes of pain, swelling and infection in the body’s internal organs and to examine an unborn child (fetus) in pregnant women.
Can dogs hear ultrasonic sounds?
Katherine Houpt, an environmental factors expert at Cornell University’s College of Veterinary Medicine, says pets routinely respond to sound above the frequencies humans can hear, called ultrasound. But dogs can hear sounds up to 45,000Hz and cats up to 64,000Hz.
What is ultrasonic and infrasonic examples?
Sound produced by earthquakes, thunder, volcanoes are in Infrasonic range. Human Ear cant hear this sound but elephants and whales can hear this. Frequencies above 20,000 Hz are in the ultrasonic range. The audible range of dogs, cats, moths and mice extends into ultrasound frequencies.
