• Scientists finally solve the mystery of the horse whinny A horse’s whinny may sound like a single call, but it is actually a blend of both high and low frequencies • In a study published February 23 in the Cell Press journalCurrent Biology, researchers explained how horses manage to produce these very different sounds at the same time • They generate the lower tone by vibrating their vocal folds, similar to the way humans create sound while singing • At the same time, they create a high pitched sound by whistling inside the larynx • According to the research team, this ability likely evolved so horses can send more than one message in a single vocalization • “We now finally know how the two fundamental frequencies that make up a whinny are produced by horses,” says author Elodie Briefer of the University of Copenhagen

  • Scientists finally solve the mystery of the horse whinny - Date: - February 25, 2026 - Source: - Cell Press - Summary: - Horses have a vocal trick no one fully understood until now. Scientists have discovered that when a horse whinnies, it produces two completely different sounds at the same time. One is a deep tone created by vibrating the vocal folds, similar to how humans sing. The other is a high-pitched whistle generated inside the larynx, something never before confirmed in a large mammal. This rare ability, known as biphonation, likely helps horses send multiple emotional signals in a s
