But new research suggests perhaps giraffes do have a distinct sound: They hum. It’s long been assumed that unlike other animals, giraffes are largely silent beasts. The researchers suspected the reason no one heard giraffe communication was because the sound frequency was too low for humans to hear. Giraffes do have a larynx (voice box), but perhaps they couldn’t produce sufficient airflow through their 13-foot long (4 meter) trachea to vibrate their vocal folds and make noises. During courtship, males emit loud coughs. Giraffe are mute… Although generally quiet and non-vocal, giraffe have been heard to communicate using various sounds.

There is even some evidence that they communicate with each other with the help of special vocalizations such as bleating or grunting. But according to the modern data, they do have well-developed vocal cords. There is a popular myth that these animals are mute. People had earlier speculated that giraffes are unable to produce any substantial sounds because it is physically difficult for them to generate sufficient airflow through their long necks to produce vocalisations. The researchers recorded animals at three European zoos, amassing 947 hours of recordings over eight years.īiologists say they have discovered that giraffes hum. Do giraffes vocalize?īut University of Vienna researchers now say they’ve determined that giraffes do indeed “produce vocalizations” that may serve as a means of communication. Giraffes will hum at night, and do so within the range of human audibility. The sound, if it were audible to human ears, would probably be a whooshing “PSSHHH!” When recorded with specialized equipment, giraffes can be observed moving their long necks and listening to each other as these infrasonic sounds are created.
