The invention relates to a power ultrasonic coupling medium comprising a liquid aqueous solution of a hydrophilic polymer, in particular polyvinylpyrrolidone.L'invention also relates to an ultrasound therapy apparatus, comprising a therapy transducer adapted to emitting ultrasound therapy, arranged in an ...
The employment of air as an acoustic coupling medium for ultrasound from 100 to 1500 kHz does demand, however, adroit planning and considerable finesse on the part of the experimenter or designer of nondestructive inspections. Under the right circumstances nonetheless, air-coupled (A-C) ultrasonics...

Ultrasound irradiation enhanced the removal of organic matter due to the activation of oxidant species in both supporting electrolytes. Moreover, the formation of chlorine gas in the chloride containing medium improves the ultrasound cavitation effect, promoting faster depletion of the total organic ...
A coupling () transmits ultrasound energy along an independent axis (A) between a tool receptacle () and a tool () having two contact means () directed opposite each other, which can be axially biased using a pre-stressing, biasing means (), wherein at least one contact means () has ...
Acoustic coupling is produced between a sonic transducer (1) and a measuring medium at an opening of a wall (2) confining the medium. The transducer is mounted in a damping material (4) for acoustic decoupling from the wall, positioned between the transducer and the edge of the wall filling...
