Akustilised sobituskihid on ultrahelimuundurite olulised komponendid, kuna sobivate sobituskihtideta põhjustab ultrahelimuunduri ja toru seina vaheline suur akustilise takistuse erinevus suurema osa ultrahelienergia kao.
Acustic matching layers are crucial components in ultrasonic transducers. Without proper matching layers, large acoustic impedance mismatch between ultrasonic transducer and the pipe body tissue will cause most of the ultrasound energy to lose.
