when I am hearing huge very low bass, she says I am crazy, she does not hear it!, and then at the same time, the woman, the wife can hear higher notes!, explain that one?, Is it because they have smaller ear drums?
It's just genetic adaptation. Over the millenia, women's ears have evolved so they could hear the highs better (to help them hear a baby crying, etc.) and conversely their response to lower frequency sounds has decreased, such as the sound of a deep male voice asking them to get you a beer.
