Weber's law states that the perceived magnitude of a stimulus change is proportional to the initial intensity of the stimulus. In this case, the initial volume level is the stimulus intensity, and raising it by 5 decibels is the change in stimulus. The noticeable difference in perception of the change in volume when the initial volume is low versus high supports Weber's law. The other options are not relevant to this phenomenon.
