2. Sonochemistry - Wikipedia

   en.wikipedia.org/wiki/Sonochemistry

   Sonochemistry. In chemistry, the study of sonochemistry is concerned with understanding the effect of ultrasound in forming acoustic cavitation in liquids, resulting in the initiation or enhancement of the chemical activity in the solution. [1] Therefore, the chemical effects of ultrasound do not come from a direct interaction of the ultrasonic ...

3. Therapeutic ultrasound - Wikipedia

   en.wikipedia.org/wiki/Therapeutic_ultrasound

   Ultrasound is applied using a transducer or applicator that is in direct contact with the patient's skin. Gel is used on all surfaces of the head to reduce friction and assist transmission of the ultrasonic waves. Therapeutic ultrasound in physical therapy is alternating compression and rarefaction of sound waves with a frequency of 0.7 to 3.3 MHz.

4. Ultrasound energy - Wikipedia

   en.wikipedia.org/wiki/Ultrasound_energy

   Ultrasound energy, simply known as ultrasound, is a type of mechanical energy called sound characterized by vibrating or moving particles within a medium. Ultrasound is distinguished by vibrations with a frequency greater than 20,000 Hz, compared to audible sounds that humans typically hear with frequencies between 20 and 20,000 Hz. Ultrasound ...

5. Ultrasound - Wikipedia
