This is because the human ear has a characteristic sense of volume, The sound is relatively small, the feeling of the human ear is very sensitive to changes in volume, but loud after a certain value, Even if the sound has greatly increased the human ear feeling will not change much. Corner characteristic exponential characteristic resistance potentiometer and auditory contrast, do so using this potentiometer volume control, the volume can be varied uniformly When adjusting the volume, but will not open a little voice becomes very large or very small.
