It's not just us and Barry White, folks. Bass is sexy! http://www.guardian.co.uk/science/2012/aug/02/elephants-deep-bass-tones?newsfeed=true "Elephants are the Barry Whites of the animal kingdom, research has shown. They produce their own version of the legendary soul singer's seductive bass tones only much, much deeper. An elephant's infrasound rumble, often too low for the human ear to hear, is used to keep herds together, and by males to find mates. It allows the animals to communicate over distances of up to six miles."
