What is meant by ultrasonic sound

An ultrasonic sensor emits a sound pulse in the ultrasonic range.The word ultrasonic derives from the latin words ultra, meaning beyond, and sonic, meaning sound, is a term used to describe sound waves that vibrate more rapidly than the human ear can detect.Ultrasonics, vibrations of frequencies greater than the upper limit of the audible range for humans—that is, greater than about 20 kilohertz.See ultrasonic welding and saser.The term sonic is applied to ultrasound waves of very high amplitudes.

The vibrations are transmitted to a diaphragm, which in turn transmits waves through a liquid, not unlike a stereo speaker transmitting sound through the air.Ultrasound as a noun means ultrasonic waves, used in medical and dental diagnosis and therapy, in cleaning and detecting flaws in metal, etc.The use of ultrasonic waves for diagnostic or therapeutic purposes, specifically to image an internal body structure, monitor a developing.An image produced by ultrasound.This limit varies from person to person and is approximately 20 kilohertz (20,000 hertz) in healthy young adults.

In medicine, ultrasound machines emit ultrasonic waves that echo back an image of a fetus or internal organ.To receive and transmit ultrasonic sound, the sensor's transducer functions as a microphone.Ultrasonics is the science and technology of ultrasound.Quite simply, it means that this form of cleaning uses ultrasonic waves, or sound that is far higher than the human ear can detect.Our ears pick up these vibrations, translating them into sounds.

By definition, a sound wave travels at.
