How do lions and tigers roar?

Of all the cats, lions and tigers produce the loudest roars – loud enough to rattle the suspension of any nearby vehicles. Fatty folds in the throats of these big cats vibrate to create and amplify that sandpapery roaring sound with just a little bit of air pressure from the lungs. Leopards and jaguars – the only other cats that can roar – also have these folds.

The cats are also aided by the strength of their vocal folds, which can withstand stretching and shearing as air moves past them and the folds vibrate. The size of the animal or the vocal fold, or the frequency of the sound, didn’t matter. Elk have vocal folds about the same size, but they make high-pitched sounds. And humans speak in a range of sound frequencies similar to those of lions’ and tigers’ roars, but obviously our voices are much softer.
