Ahhhh love. It's grand. But what sound do couples in love find comforting? 

Research by Amplifon found the most comforting sounds to couples. I personally don't think you have to be a couple to enjoy these soothing sounds, but that's what the research was.

Cool...we came in second!

Okay, it's not really a picture of humming, but of a humming bird. Do you know how hard it is to find a picture of someone humming?

Do you find these sounds soothing? I actually really don't enjoy humming at all - but I LOVE humming birds. Weird.
