Near miss to Weber’s law occurs for tones but not noise

Evidence

Weber’s law did not hold for tones. In fact, the JND, when expressed as a proportion of the intensity of the stimulus, decreased with increasing intensity across the audible range. This phenomenon is called the near miss to Weber’s law. Note that we observe this result only for tones and not noise at levels greater than 20 dB SL. — Jennifer Lentz, Psychoacoustics- Perception of Normal…, 824
