Ultrasound cannot be heard as it has a higher frequency than audible sound, with a frequency above 20000Hz.

Ultrasound imaging is the name for the use of high frequency sound waves in an imaging process used to diagnose patient illness.
Ultrasound. Diagnostic ultrasound is the use of high-frequency sound waves to image anatomic structures and to detect the cause of illness and disease. Ultrasound moves at different speeds through the body's tissue, depending on the density of the tissue.
They are known as Overtones. If they are beyond the range of human hearing, they are called ultrasound, or ultrasonic waves.
The wavelength of ultrasound can be calculated using the formula: wavelength = speed of sound / frequency. Assuming the speed of sound in human tissue is about 1540 m/s, the wavelength of 3.5 MHz ultrasound would be approximately 0.44 mm.
Difference is in their frequency, audible sound waves is between 12 Hz and 20,000 Hz, Ultrasound waves is any sound that has a frequency beyond the 20,000 Hz limit
the sound would be called "ultrasound"
Sonar, ultrasound, high-frequency sound.
Sonic infrasound is a sound too low for humans to hear, below 20 Hertz. Ultrasound is a sound too high for humans to hear, above 20,000 Hertz.
Infrasound is always smaller or lighter than ultrasound. For example: infrasound can be the sound of a paper clip hitting the floor, and ultrasound can be the sound of two planets colliding.
Endorectal ultrasound (ERUS) is a procedure where a probe is inserted into the rectum and high frequency sound waves (ultrasound waves) are generated
"Sound" is a mechanical wave traveling through a medium. Ultrasound is sound, but its frequency is higher than humans can hear.
The ultrasound principle is this: when a high-frequency sound is produced and aimed at a target, it will be reflected by its target and the reflected sound can be detected back at its origin.
Ultrasound is cyclic sound pressure with a frequency greater than the upper limit of human hearing. This frequency varies from person to person, it is approximately 20 kilohertz (20,000 hertz). This is the lower limit in describing ultrasound.
The ultrasound machine tends to direct high-frequency sound waves at the internal body structures being examined.
