What is the amplitude of an ultrasound wave?

The maximum height of the wave cycle is the amplitude of the ultrasound wave. The product of the frequency (ν) and the wavelength (λ) is the velocity of the wave; that is, c = νλ. In most soft tissues, the velocity of ultrasound is about 1540 m/sec.

Can ultrasounds travel through air?

Because ultrasound waves do not pass through air, ultrasound evaluations of the stomach and/or small and large intestines may be limited. Intestinal gas may also prevent visualizing the deeper structures such as the pancreas and aorta.

Can you feel ultrasonic vibrations?

You cannot feel these vibrations, however. Ultrasound also creates heat in tissues that absorb the sound waves, such as tendons, ligaments, and bone.
