A bat detector is a specialized device used to detect and analyze the ultrasonic vocalizations of bats. Bats communicate and navigate using echolocation, emitting high-frequency sounds that are often above the range of human hearing (typically 20 kHz to 200 kHz). Bat detectors convert these high-frequency sounds into lower frequencies that can be heard and analyzed by humans.
