Entropy has become important as a phenomenon of contemporaneity in art practice and theory. Since the composer Karlheinz Stockhausen stated the problem in his essay Structure and Experiential Time (1955), several authors focused their studies on the influence of the rate of auditory information in the perception of elapsed time. In this article the influence of physical duration and some aspects of entropy on perceived duration of a sound stimulus of about 35 s is studied. Dispersion of time interval between onset of events and the temporal density of events are aspects possibly related to the entropy. An experiment is conducted and preliminary results about the influence of entropy on the perception of duration are discussed.
