antinoise
|an-ti-noise|
/ˈæn.ti.nɔɪz/
signal against noise
Etymology
'antinoise' is a modern English compound formed from the prefix 'anti-' meaning 'against' (from Greek anti-) + the noun 'noise' (Modern English).
'antinoise' formed in 20th-century technical and engineering contexts by compounding 'anti-' and 'noise'; 'noise' itself comes into English via Old French 'noise' (meaning 'quarrel, disturbance') ultimately influenced by Latin 'nausea' in sense of displeasure or disturbance.
Originally, 'anti-' meant 'against' and 'noise' meant unpleasant sound/disturbance; combined, 'antinoise' came to mean an opposing signal or quality that cancels or reduces unwanted sound.
