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 no difference value for a ratio is 1.00, and the log of this is zero. It is also easy to calculate standard errors and confidence intervals for the log of the ratio. Results are often shown on a logarithmic scale, i.e. one where the scale intervals are logarithms, but the numbers given are the actual ratios.
