Decibels are not additive, since they measure changes on a logarithmic scale ; so that it is the ratio of two sound intensities which determines their difference in decibels. ... Thus doubling the intensity of a sound, as when two similar voices sing the same note, corresponds to a change of 3 decibels.
Is 60 decibels twice as loud as 50?
Loudness and Sound Intensity (Power)
Most of us perceive one sound to be twice as loud as another one when they are about 10 dB apart; for instance, a 60-dB air conditioner will sound twice as loud as a 50-dB refrigerator.
How much louder is 20 dB compared to 10 dB?
A 20 dB sound is 10 times louder than a 10 dB sound. The level of noise in a quiet bedroom, 30 dB, is 100 times louder than 10 dB. And 40 dB is 1,000 times louder than 10 dB. A typical conversation clocks in at around 60 dB.
