On the basis of equal‐loudness contours expressed in terms of volume velocity of cochlear fluid, a theory is developed for equal loudness at high levels of stimulation. At these levels the theory assumes number of active nerve fibers to be proportional to volume velocity of cochlear fluid, and firing rate of fibers to be limited by the refractory period. Analysis of a set of threshold data seemed to confirm these assumptions, and was in disagreement with the notion of power summation at the absolute threshold.
