Owls' Silent Flight Inspires New Noise Reduction Technology

Towards silent and efficient flight by combining bioinspired owl feather serrations with cicada wing geometry

As natural predators, owls fly with astonishing stealth due to the serrated feather morphology that produces advantageous flow characteristics. Traditionally, these serrations are tailored for airfoil edges with simple two-dimensional patterns, limiting their effect on noise reduction while negotiating tradeoffs in aerodynamic performance. Conversely, the intricately structured wings of cicadas have evolved for effective flapping, presenting a p…

Owls' silent flight inspires new noise reduction technology

If you've seen an owl fly, you probably didn't hear a thing. That's because their skin and feathers dampen sound by absorbing high- and low-frequency flight noise.

Silent owls inspire breakthrough in noise reduction technology

Owls are known for their ghostly silent flight, gliding through the air without making a sound. Now, scientists have taken inspiration from these quiet hunters to design a new material that could help reduce noise pollution in our daily lives—from traffic to loud machinery. The research was published in ACS Applied Materials & Interfaces. The […] The post Silent owls inspire breakthrough in noise reduction technology appeared first on Knowridge …
