Afin de réduire à un échelle plus commode la très vaste gamme de pressions acoustiques, on utilise l'échelle des décibels (dB). Les niveaux de pression acoustique exprimés en dB traduisent plus facilement les impressions de l'oreille humaine. Une modification du niveau de 10 dB correspond approximativement à doubler l'intensité perçue [...]. Sur l'échelle des décibels, un chuchotement à 2 m de distance aurait un niveau sonore d'environ 35 dB(A) alors que le niveau sonore moyen des bruits de fond dans un bureau serait d'environ 40 dB(A). Un marteau-perforateur à 15 m de distance peut engendrer un niveau sonore de 95 dB(A), alors que dans une discothèque les niveaux de bruit peuvent atteindre 110 dB(A). 2, record 3, French, - %C3%A9chelle%20des%20d%C3%A9cibels

The unit of measurement of environmental noise is the decibel (dB). To better approximate the range of sensitivity of the human ear to sounds of different frequencies, the A-weighted decibel scale was devised. Because the human ear is less sensitive to low-frequency sounds, the A-scale de-emphasizes these frequencies by incorporating frequency weighting of the sound signal. When the A-scale is used, the decibel levels are shown as dBA. On this scale, the range of human hearing extends from about 3 dBA to about 140 dBA. A 10-dBA increase is perceived by most people as a doubling of the sound level. The smallest change that can be heard is about 2 to 3 dBA. 2, record 6, English, - A%2Dweighted%20decibel
