Typically, females are able to hear things better than males. (Gurian, Michael, and Patricia Henley, with Terry Trueman. Boys and Girls Learn Differently! p 30. CA: Jossey-Bass, 2001.)
Females have better hearing for high sounds and are more sensitive to loud noises. Males tend to prefer louder volume for both music and speech at every frequency. (Fisher, Helen, PhD. The First Sex. p 86-87. NY: Random House, 1999.)
