What Are the Properties of Sound?

There 's a very direct correlation between this acoustic property of roughness and the extent to which, as a listener, you interpret the sound as frightening or alarming. So i think there's maybe a difference between positive and negative affect signals because they serve a very different function. And sounds can bond people, bring us together in spiritual ways. What is it about our bodies and minds that allow us to connect this way? Is there a way to measure something so abstract?
