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 …

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 …

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

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 …

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 …

Feb 9, 2025 · Infrasonic and ultrasonic waves describe sounds outside the human hearing range, with unique applications in environmental monitoring and medical imaging, respectively.

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 …

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 …

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 …

Ultrasonic waves are sound waves that have frequencies beyond the typical human hearing range, usually above 20 kHz. These waves are not audible to humans but have numerous …
