We do not hear the screams of bats because they use ultrasonic vocalizations, which are sounds above the human hearing range of 20 Hz to 20 kHz. Bats typically emit these high-frequency sounds, primarily for echolocation, to navigate and locate prey in the dark. Since these frequencies are beyond human capability to hear, we are unaware of their vocalizations.
