Elephants are well known for their trumpetlike sounds, but they can “sing” superlow songs, too. You’ll never hear these tunes in full, though. That’s because elephant songs include notes too low for the human ear to hear.
Some scientists had suggested that elephants make these low sounds in the same way that cats purr — by squeezing muscles near the voice box, or larynx. But elephants don’t need to use throat muscles to go low, say scientists in a newly published study.
