Studies done in my favorite Dutch city have found that when listening to white noise the primary auditory cortex has a significantly higher activation in the brains of women than in the brains of men. However, both sexes have the same activation when listening to music, significantly higher than the noise stimulus. This means both men and women pay more attention to music than to white noise (not surprising), but women pay more attention to white noise than men. I leave it up to you whether this result is surprising or not.
