: Most bats emit sounds between 20 kHz and 200 kHz [1]. For context, the upper limit of human hearing is roughly 20 kHz [2].

: When slowed down, these high-frequency "clicks" and "chirps" often sound like a series of rhythmic bird-like chirps or metallic "tinks" [4, 5]. heres_what_bat_echolocation_sounds_like_slowed_...

: Slow, steady pulses as the bat scans the environment [6]. : Most bats emit sounds between 20 kHz and 200 kHz [1]

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]. The Mechanics of Echolocation : Slow, steady pulses as the bat scans the environment [6]

: Just before capture, the bat emits a rapid-fire burst of sound—sometimes hundreds of pulses per second—to get high-resolution tracking data in the final milliseconds [4, 6]. How We Record It
