Scarlett Johanssen’s deep giggles in Vicky Cristina Barcelona… Tom Hardy’s crazy Bane voice in Batman Begins – there are certainly those out there with famously sexy voices… but what about them truly gets our wheels turning? Turns out it’s SCIENCE.

Via HuffPo:

Before you shake your head at the absurdity of having a voice so good, you’d screw it if possible, imagine, say, Jon Hamm telling you exactly what he wants to do to you in bed. Now imagine Jared Kushner, a man whose voice has been likened to “a young Michael Cera” and “a sassy Kermit the Frog,” telling you the very same thing. Completely different experience, right?

So what exactly sets a sexy voice apart from others? Studies show that women tend to prefer men with deep voices, which are linked to higher testosterone levels and general reproductive prowess. Men, meanwhile, are drawn to women with high-pitched voices, which are associated with high estrogen levels, perhaps serving as a cue to a woman’s health and fertility.
