Morphology

anechoic = echoic (transparent) = an + echo + ic

Formed by prefixing 'an-' (not) to 'echoic' (relating to echoes); the resulting meaning 'without echoes' is predictable though the term is technical.

Etymology

Anechoic comes from the Greek parts an- meaning 'without' and echo meaning 'a sound that comes back'. So an anechoic room is 'without echoes', which is why it absorbs sound instead of letting it come back.
