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 pH scale. The pH scale is used to rank solutions in terms of acidity or basicity (alkalinity). Since the scale is based on pH values, it is logarithmic, meaning that a change of 1 pH unit corresponds to a ten-fold change in H+^+â+ââstart superscript, plus, end superscript ion concentration.
