The ear mechanism is able to respond to both very small and very large pressure waves by virtue of being nonlinear; that is, it responds much more efficiently to sounds of very small amplitude than to sounds of very large amplitude. Because of the enormous nonlinearity of the ear in sensing pressure waves, a nonlinear scale is convenient in describing the intensity of sound waves. Such a scale is provided by the sound intensity level, or decibel level, of a sound wave, which is defined by the equation Here L represents decibels, which correspond to an arbitrary sound wave of

Intensity and the Decibel Scale – The Physics Classroom

Physics Tutorial: Intensity and the Decibel Scale

The amount of energy that is transported by a sound wave past a given area of the medium per unit of time is known as the intensity of the sound wave. Intensity is the energy/time/area; and since the energy/time ratio is equivalent to the quantity power, intensity is simply the power/area. Since the range of intensities that the human ear can detect is so large, the scale that is frequently used to measure it is a scale based on powers of 10. This type of scale is sometimes referred to as a logarithmic scale. The scale for measuring intensity is the decibel scale.
