: When slowed down, these high-frequency "clicks" and "chirps" often sound like a series of rhythmic bird-like chirps or metallic "tinks" [4, 5].
: By listening to the echoes that bounce back, bats determine an object's size, shape, distance, and even its texture [1, 6]. Phases of the Hunt heres_what_bat_echolocation_sounds_like_slowed_...
: 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
Since we cannot hear these sounds naturally, researchers use [5, 7]. These devices use specialized microphones to capture high-frequency audio and then either heterodyne it (shifting the pitch) or use time expansion (slowing it down) so humans can study the intricate patterns of their "acoustic maps" [5, 7]. For context, the upper limit of human hearing
: Slow, steady pulses as the bat scans the environment [6].
