What is the hearing range of chimpanzee?

Chimpanzees have a hearing range that typically spans from about 1 kHz to 4 kHz, although they can perceive sounds up to around 20 kHz. This range is similar to that of humans, but chimpanzees are particularly attuned to sounds that fall within the frequency range of vocal communications among their species. Their acute sense of hearing helps them detect important environmental cues and social signals.
