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.
A logarithmic scale means that there is a ten-fold difference between each successive full number on the scale. An acidic solution reading 4.0 represents a ten-fold increase in acidic molecules over a 5.0 solution. The acidic difference between a 4.0 solution and a 6.0 solution is 100 times greater (10x10). Hydrochloric acid or muriatic acid is an extremely caustic solution that sits at the extreme end of the acidic scale.
