What the actual fuck....
I'll draw you to this extract of studies:
Corso (1959) was among the first to report that females have superior auditory acuity (i.e. lower thresholds) compared with same-age males, particularly for test frequencies above 2 kHz. The same general finding – adult females having more sensitive hearing at high frequencies, compared with same-age males – has been replicated in other studies of adults (e.g. Chung, Mason, Gannon, and Willson, 1983; Royster, Royster, and Thomas, 1980), including studies with Caucasian, African-American, and Asian adults (Dreisbach and colleagues, 2007; Shahnaz, 2008)
So perhaps me and old MK could have a hearing contest, one to hear the highest frequencies wins...I'd win each time because of my biological advantage, then perhaps he will change his tune (pun intended)
