Noise Level Chart
A noise level chart showing examples of sounds with dB levels ranging from 0 to 180 decibels.
Most noise levels are given in dBA, which are decibels adjusted to reflect the ear's response to different frequencies of sound. Sudden, brief impulse sounds, like many of those shown at 120 dB or greater, are often given in dB (no adjustment). Noise ChartSpecifics about the measurement of a particular sound source can be found in the Noise Navigator® Sound Level Database, E-A-R 88-34/HP, by Elliott H Berger, Rick Neitzel, and Cynthia A Kladden, E•A•RCAL Laboratory, 3M Occupational Health & Environmental Safety Division, an extensive compilation of data on noise level measurements, including many of the values appearing on this chart.
