Scientists Discover Horses Can Whistle and Sing at the Same Time
Horses produce two-tone calls via vocal fold vibrations and a laryngeal whistle, enabling complex communication with distinct emotional messages, researchers said.
- Scientists have discovered that horses produce their signature call, known as a whinny, by using two different sound-making systems simultaneously: vibrating their vocal folds like humans singing to create a low tone, and also generating a high-pitched whistle inside their larynx.
- This dual sound production likely evolved so that horses can communicate more than one message in a single call, with the two fundamental frequencies conveying different messages about the horse's emotions.
- Despite living alongside humans for over 4,000 years, scientists still know relatively little about how horses communicate vocally, and the whinny's surprisingly high frequencies for such a large mammal had remained a mystery until this study.

A horse's whinny is unique in the animal kingdom, scientists say
Horses whinny to find new friends, greet old ones and celebrate happy moments, like feeding time. But how exactly they produce the distinctive sound - also called a neigh - has long eluded scientists. That mystery has been solved - its a combination of whistling and singing. The two-toned whinnies could help them convey multiple messages say scientists.

In new investigations, researchers have discovered a rare tuning phenomenon in horses. Their whining consists of two simultaneous basic frequencies.
Study focused on horse racing mechanism, since horses, such as bears and zebras, do not seem to have the acute component, suggesting that horses have unique vocal adaptations.
