Intensity level is given by b = 10 log(I/I0) with I0 = 10−12 W/m2. The usual threshold of human hearing is defined as intensity level of b = 0 dB. What does this actually mean in terms of sound intensity?

    The decibel scale is a logarithmic scale for measuring the sound intensity level. Because the decibel scale is logarithmic, it changes by an additive constant when the intensity as measured in W/m2 changes by a multiplicative factor. The number of decibels increases by 10 for a factor of 10 increase in intensity. The general formula for the sound intensity level, in decibels, corresponding to intensity I is β=10log(II0)dB, where I0 is a reference intensity. For sound waves, I0 is taken...
