How to measure decibels.

Decibels are measured using a logarithmic scale, which is different from the commonly-used linear scale. For linear scales, the measure between two points will never change. Three inches is two inches more than one, and one inch is four fewer than five. Logarithmic scales, however, measure percent changes.
