yes it is. giraffe produce infrasound for vocalizations.The giraffe, a savanna ungulate, possessing limited auditory vocalizations, was found to produce infrasound. Recordings were made of 11 Giraffe (Giraffe camelonardalis reticulata), at the North Carolina Zoological Park in Asheboro, North Carolina and the Riverbanks Zoo and Botanical Garden in Columbia, South Carolina. A portable system (7 Hz – 22 kHz) was used to record the vocalizations. Additionally, the decibel levels of the inaudible signals decreased rapidly over 40 Hz, which suggests that the vocalization may be designed to be a covert form of communication. The hypothesis that giraffe, like okapi, elephant, whale, and rhinoceros produce infrasound, was supported.
