What does echoic mean?
Echoic is an adjective used chiefly in linguistics to describe words that have been coined by imitating the sounds they refer to — words such as hiss, bang, splash, and buzz, whose forms echo the noises of the world. In this sense it is closely related to, and often interchangeable with, the more familiar term onomatopoeic. The adjective also has a distinct life in psychology: echoic memory refers to the fleeting auditory store that holds raw sound for a second or two after it reaches the ear. Derived from the noun echo via Greek ēchō, the word entered English as part of the scholarly vocabulary of phonetics. It is formal rather than colloquial, and writers typically reach for it when discussing how language mirrors sound, whether in child speech acquisition, poetry, or the study of animal communication. Its usefulness lies in naming precisely what ordinary speakers sense intuitively: that some words do not merely mean a sound but reproduce it.
(Of a word or form) created in imitation of a natural sound; onomatopoeic.
"'Cuckoo' is one of the most famous echoic words in English."
Common in linguistics and phonetics; rarer outside technical contexts.
Relating to the short-lived auditory sensory memory system (echoic memory).
"The melody lingered briefly in her echoic buffer before fading entirely."
Restricted almost entirely to psychological literature.
Every 'hiss', 'bang' and 'buzz' you say is a tiny piece of linguistic archaeology — echoic words are fossils of sound itself.

Etymology of echoic
Echoic derives from the noun echo, which English borrowed from Latin and ultimately from Greek ēchō, meaning a resounding sound or reverberation. Combined with the adjectival suffix -ic, it emerged in English as a technical term in nineteenth-century philology and phonetics to label words formed by imitation of sound. The same Greek root underlies a family of modern coinages such as echolocation and echolalia, which likewise involve sound reflected, repeated, or reproduced.

How echoic is actually used
Echoic is primarily a technical term in linguistics and phonetics, though it appears in general writing about language and in psychology (echoic memory). It is formal to neutral in register and carries no strong connotation. It should not be used loosely to mean simply 'reverberant' or 'full of echoes'.
Easily confused with echoic
Echoic describes language that imitates real-world sounds, whereas echoing describes an actual sound being repeated or reverberating.
