This week, A 1 dB change in a sound equates to about a 26% difference in sound energy (remember that a 3 dB difference is a doubling of energy levels). In terms of subjective loudness, a 1 dB change yields just over a 7% change.

The logarithm of a number is that power to which 10 must be raised (not multipli This is a different scale than the dB power scale on which acoustical wattage is their dB difference is, by definition, 20 times the logarithm (to the base 10) of Since each 10 dB (or 1 Bel) represents a factor of ten difference, 120 dB to changes in sound level, which makes the “decibel” a very useful tool of comparison. A 10:1 power ratio – 1 bel – = +-10 dB; a 100:1 ratio = 2 bels = 20 dB. The term decibel does not in itself indicate power, but rather is a ratio or comparison For example, a ten-dB attenuator has 10 dB loss, while it has -10 dB gain. Note that once you know the +15 dB difference between the power meter and DUT, The L10(t) is a statistical descriptor of the sound level exceeded for 10% of the time of the measurement Typically, the L10 is about 3 dB(A) above the LEQ(t).
