Ultrasonisk
Ultrasonisk refers to sound waves with frequencies above the upper limit of human hearing, typically exceeding 20 kilohertz (kHz). These high - frequency mechanical waves are generated and detected using piezoelectric transducers, which convert electrical energy into ultrasonic vibrations and vice versa.
In medical applications, ultrasonics is widely used for diagnostic imaging, such as B - mode ultrasound, which
Industrial uses include non - destructive testing (NDT) to inspect materials for defects, ultrasonic cleaning to remove
The technology relies on the principle that ultrasonic waves can penetrate various media and reflect off boundaries
