Linear vs logarithmic scales. 1  Human hearing is better measured on a logarithmic scale than a linear scale. 2  On a linear scale, a change between two values is perceived on the basis of the difference between the values.  On a logarithmic scale, a change between two values is perceived on the basis of the ratio of the two values.
The logarithm of the division of x and y is the difference of logarithm of x and logarithm of y. log b (x / y) = log b (x) - log b (y). For example: log 10 (3 / 7) = log 10 (3) - log 10 (7).
