Most of us have always assumed that giraffe’s are reasonably silent animals. However, new research suggests that giraffes may actually have a distinct sound that they only make at night.

They hum.

Like elephants, it was assumed that giraffes make sounds that aren’t audible to the human ear, but in a new study published in the BioMed Central journal found that giraffes make a distinct humming sound at night. Researchers recorded over 940 hours at three separate zoos and found that the humming was 92Hz in frequency, which humans are able to hear, but only just.

Further research is yet to be done regarding whether these noises are a form of communication however the article concluded that “these results show that giraffes do produce vocalizations, which, based on their acoustic structure, might have the potential to function as communicative signals to convey information about the physical and motivational attributes of the caller.”
