Abstract: For hearing sense, the mechanoreceptors fire action potentials when their membranes are physically stretched. Based on the statistical physics, we analyzed the entropical aspects in auditory processes of hearing. We develop a model that connects the logarithm of relative intensity of sound (loudness) to the level of energy disorder within the system of cellular sensory system. The increasing of entropy and disorder in the system is connected to the free energy available to signal the production of action potentials in inner hair cells of the vestibulocochlear auditory organ.
