Hypertrichosis pinnae auris may enhance the hearing power of an individual.

In this correspondence, we hypothesize that the hypertrichosis pinnae auris might influence the hearing power of an individual. It is a well established fact that the inner cells of the ears acts as sensory cells which respond to the incoming sound vibrations. The occurrence and degree of hairiness have been reported to increase with advancing age; therefore, we theorize that there might be the presence of the sensory activity in the hairs present on the outer area of the ear, which would enhance the hearing ability of the individuals.
