[Middle English, from Old French, perhaps from Vulgar Latin *nausea, discomfort, from Latin nausea, seasickness; see nausea.]
Synonyms: noise, din, racket2, uproar, pandemonium, hullabaloo, hubbub, clamor, babel
These nouns refer to loud, confused, or disagreeable sound or sounds. Noise is the least specific: deafened by the noise in the subway.
A din is a jumble of loud, usually discordant sounds: the din of the factory.
Racket is loud, distressing noise: the racket made by trucks rolling along cobblestone streets.
Uproar, pandemonium, and hullabaloo imply disorderly tumult together with loud, bewildering sound: "The evening uproar of the howling monkeys burst out" (W.H. Hudson); "a pandemonium of dancing and whooping, drumming and feasting" (Francis Parkman); a tremendous hullabaloo in the agitated crowd.
Hubbub emphasizes turbulent activity and concomitant din: the hubbub of bettors, speculators, tipsters, and touts.
Clamor is loud, usually sustained noise, as of a public outcry of dissatisfaction: "not in the clamor of the crowded street" (Henry Wadsworth Longfellow); a debate that was interrupted by a clamor of opposition.
Babel stresses confusion of vocal sounds arising from simultaneous utterance and random mixture of languages: guests chattering in a babel of tongues at the diplomatic reception.
Word History: Those who find that too much noise makes them ill will not be surprised that the word noise can possibly be traced back to the Latin word nausea, "seasickness, feeling of sickness." Our words nausea and noise are doublets, that is, words borrowed in different forms from the same word. Nausea, first recorded probably before 1425, was borrowed directly from Latin. Noise, first recorded around the beginning of the 13th century, came to us through Old French, which explains its change in form. Old French nois probably also came from Latin nausea, if, as seems possible, there was a change of sense during the Vulgar Latin period, whereby the meaning "seasickness" changed to a more general sense of "discomfort." Word meanings can sometimes change for the better, and nowadays, of course, a noise does not have to be something unpleasant, as in the sentence "The only noise was the wind in the pines."
