Scientists have discovered source of neigh’s unique combination of high- and low-pitched sounds
Horses whinny to find new friends, greet old ones and celebrate happy moments like feeding time.
How exactly horses produce that distinctive sound – also called a neigh – has long eluded scientists.
The whinny is an unusual combination of both high- and low-pitched sounds, like a cross between a grunt and a squeal – that come out at the same time.
The low-pitched part wasn’t much of a mystery. It comes from air passing over bands of tissue in the voice box that make noise when they vibrate. It’s a technique similar to how humans speak and sing.
