An increase of 3dB doubles the sound intensity but a 10dB increase is required before a sound is perceived to be twice as loud. Therefore a small increase in decibels represents a large increase in intensity. For example – 10dB is 10 times more intense than 1dB, while 20dB is 100 times more intense than 1dB.

It is a logarithmic unit that describes a ratio of two intensities, such as two different sound pressures, two different voltages, and so on.
