So it's not biological significance... You are born loving the sound “shush,” white noise. This is also the great irony of people complaining about distortion and thick bassy kick beats, we actually like it because it's warm and “takes us back”: indeed even to the noisy slushy womb and the heartbeat there. Rather it's that things that hit one tone either also tickle the hairs in your organ of Corti at 2x, 3x, 4x, 5x the frequency (strings) or at 3x, 5x, 7x, 9x the frequency (half-open acoustic resonators—guitar bodies, panflutes), and your brain feels comfortable when those tickle together as they are familiar.
