The great grey owl basically has a sound cone for a face, which helps it hunt down voles burrowing through snow in the winter ...

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. Inspired by this natural ...

Trailing-edge noise is the dominant source of sound from aeronautical and turbine engines like those in airplanes, drones, and wind turbines. Suppressing this noise pollution is a major environmental ...

Noise pollution is more than annoying. Research has shown its impact on fish, songbirds and the health of humans too. But nature itself may offer a solution, with scientists in China reporting that ...

A new sound-suppression study provides fresh insight for airfoil design and noise control for micro-aircraft and fluid machinery. The research focused on the concept of trailing-edge noise by using ...

Researchers used the characteristics of owl wings to inform airfoil design and significantly reduce trailing-edge noise. The team used noise calculation and analysis software to conduct a series of ...
