The just noticeable difference (JND) is a constant proportion of the original stimulus.

The sensation magnitude is proportional to the logarithm of the stimulus intensity.

The sensation magnitude is proportional to the power of the stimulus intensity.

The sensation magnitude is inversely proportional to the stimulus intensity.
