What does monaural mean?
Monaural describes something involving one ear or a single audio channel. In medicine and audiology, it can refer to hearing that occurs in only one ear, as in monaural hearing loss. In audio technology, monaural sound is reproduced through one channel, unlike stereo sound, which uses two channels, or binaural sound, which is designed to create the impression of spatial listening through two ears. The adjective is most common in technical and medical contexts, though it is also used in ordinary descriptions of recordings and playback systems. Its usefulness lies in distinguishing the number of ears or audio channels involved: monaural means one, whereas stereo and binaural imply a two-channel or two-ear experience. Although the word may sound formal, it provides a precise alternative to saying “one-ear” or “single-channel” in professional discussion.

- Relating to or involving one ear.

"The patient reported a decrease in monaural hearing after the infection."

Monaural comes from the same Greek root as monopoly and monologue, but instead of “one” it describes sound arriving through a single channel.

Where does monaural come from?
The word was formed in the 19th century from the Greek prefix mono-, meaning “one,” and aural, relating to the ear. The prefix comes from Greek monos, “single” or “alone,” while aural ultimately derives from Latin auris, “ear.” The same Greek root appears in cognates such as monody, monogram, monograph, and monopoly, all of which involve a notion of unity or singleness.
