Anechoic → It is formed from "a-" (meaning without) and "echoic" (from Greek "ēchō" meaning sound). The word describes a space that is without sound reflections, hence anechoic refers to an environment designed to eliminate echoes.
Think of a place that is 'without' ('a-') 'sound' ('echoic') — that's why anechoic describes a space free from echoes.
