Nanomaterial: Eulen inspirieren zu wirksamerem Schallschutz
Die besondere Haut und die Federn an ihren Flügeln lassen Eulen fast lautlos fliegen. Ein Material, das die Flügel nachahmt, könnte für leisere Autos und Industrieanlagen sorgen.
Very interesting! Also I’d imagine owl noises would be within a pretty specific range - 500-2000Hz say. But as you got to lower frequencies with bigger sound waves, I’d think the nano-aero-fiddly-bits would lose some effectiveness.
Oh my, don’t get me distracted running sound meters on my work owls now! 🤣
