köken: Inherited from Old French bruit, used as a noun of the past participle form of bruire (“to roar”), from a Proto-Romance alteration (by association with braire (“to bray; to cry out, shout out”)) of Latin rugītus (“brayed; bellowed, roared; rumbled”) (compare Vulgar Latin *brugitus, from Latin *brūgere). Compare also Spanish ruido, Portuguese ruído, and French rut.
aile: à bas bruit, à grand bruit, à petit bruit, antibruit, beaucoup de bruit pour rien, bruire, bruit blanc, bruit de couloir, bruit de fond, bruit de quincaillerie
