Etymology

LatinOld FrenchEnglish

Noise comes from Old French 'noise', which meant 'a disturbance, quarrel, or loud shouting'. That word probably traces further back to Latin 'nausea', meaning 'seasickness' — a discomforting experience. Over time, the meaning shifted from shouting and quarrels to any unwanted or unpleasant sound, and later expanded into technical areas like electronics and data science.
