Morphology

ultrasound = sound (transparent) = ultra + sound

The meaning follows directly from ultra- 'beyond' plus sound, referring to sound above the range of human hearing.

Etymology

Ultrasound comes from the parts ultra- and sound, with ultra- meaning 'beyond' and sound meaning what we hear, so the word means 'sound beyond hearing'. That's why ultrasound refers to sound waves higher than people can hear and is used in scans and other tests.
