use ultrasonic pulses—sounds at frequencies far above the range of human hearing—to navigate and hunt in total darkness [1, 2]. To make these sounds audible to us, scientists use "time expansion" to slow them down, often by a factor of 10 or 20, which lowers the pitch into our acoustic range [4, 5].
