Ultrasonic devices operate with frequencies from 20 kHz up to several gigahertz. Ultrasound is used in many different fields. Ultrasonic devices are used to detect objects and measure distances. …

An ultrasonic transducer is a device used to convert some other type of energy into an ultrasonic vibration. There are several basic types, classified by the energy source and by the medium into …

Ultrasonics is the only internationally established journal which covers the entire spectrum of ultrasound research, technology, and applications. It contains a variety of sections to keep its readers abreast of …

Ultrasound, or ultrasonography, works on the principle that sound is reflected at different speeds by tissues or substances of different densities. Ultrasound technology has been used medically since …

Define ultrasound and describe its characteristics as a form of energy. Explain the principles of sound wave propagation, including frequency, wavelength, amplitude, and velocity. Describe the …

The term "ultrasonic" applied to sound refers to anything above the frequencies of audible sound, and nominally includes anything over 20,000 Hz. Frequencies used for medical diagnostic ultrasound …

Ultrasonic waves are sound waves with frequencies above the upper limit of human hearing, typically above 20 kHz. These waves propagate through different media such as liquids, gases, and solids.

May 9, 2018 · The word ultrasonic combines the Latin roots ultra, meaning "beyond," and sonic, or sound. The field of ultrasonics thus involves the use of sound waves outside the audible range for …

Aug 6, 2023 · Ultrasound waves have higher frequencies than normal sound waves, but they also have shorter wavelengths. In other words, the distance between one ultrasound wave traveling through …

Sep 21, 2025 · Ultrasonic refers to sound waves that are above the frequency range of human hearing, typically above 20,000 Hz. These high-frequency sound waves are used in various applications, …
