Why do women have superior hearing?
Across all the groups involved in the study, women consistently outperformed men in hearing tests. In fact, in some populations, women’s ears were found to be six kilohertz sharper than men’s.
These results suggest that gender (or sex) plays a key role in influencing cochlear sensitivity, but why is this the case? The exact reason is still unknown, but “this could be due to different exposure to hormones during development in the womb or due to men and women having slight structural differences in cochlear anatomy,” the study authors suggest.
