The "volume" is commonly expressed in decibels (dB). The information in the decibel scales is done logarithmically in the auxiliary unit of measurement decibels, since in a linear scale the differences are hardly visible at low values. An increase of 10 decibels means a doubling of the volume.
The following scale shows the different noise levels as well as comparable events in the logarithmic arrangement:
