Bat Sounds Black Screen | 3 Hours — Sounds to Sleep To (No Light)

Real bats, heard the only way human ears can hear most of them. Bats call in ultrasound, far above our hearing — so these are genuine field recordings made audible with bat detectors, time-expansion and slowed playback: pipistrelle echolocation clicks and feeding buzzes, a Myotis colony's social chatter, and the slowed songs of Brazilian free-tailed bats. Nothing here is synthesized — every click and trill is a real bat, just shifted down into our range. Runs a full 3 hours — one seamless loop with no sudden changes from start to finish. No talking, no music, no surprises. BLACK SCREEN: the picture is there for the first minute, then fades to a true black screen for the rest of the video, so your room stays dark and your screen uses less power — sounds to sleep to. Good for: • A different kind of night sound for sleeping • Nature listening — echolocation made audible • Deep focus for working or studying • A hushed, atmospheric background for reading • Masking silence that feels too quiet • Blocking out small household noises at night Hushloop posts long-form sleep and focus sounds every week — subscribe for new sounds. If this helped you rest or focus, a like and a subscription mean a lot and help the channel grow. Thank you for listening. Listen at a comfortable volume. Don't use while driving if it makes you drowsy. — Audio credit — 1) Pipistrelle bats via heterodyne detector, Helperthorpe, North Yorkshire Author: david m, via radio aporee Source: radio aporee via the Internet Archive Item URL: https://archive.org/details/aporee_61...
