What animals can produce a wider range of frequency than humans?

Many animals can produce a wider range of frequencies than humans, including dolphins, elephants, and bats. For instance, dolphins can produce sounds that range from 20 Hz to 150 kHz, while elephants communicate using infrasound below 20 Hz. Bats utilize echolocation, emitting ultrasonic sounds that can exceed 100 kHz. In contrast, humans typically hear and produce sounds within a frequency range of about 20 Hz to 20 kHz.
