A new soundproofing material (fluffy white disk, right image) that mimics the structure of owl skin and feathers reduced the rumble of a car engine more than a traditional felt fiber soundproofing ...

WASHINGTON, January 18, 2022 -- 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 ...

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 ...

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 ...

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. Subscribe to our newsletter for the ...

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 ...

Owls have inspired new noise reduction technology. The silent flight of the aerial predators is possible because their skin and feathers dampen sound by absorbing high- and low-frequency flight noise.

Scientists from Chiba University in Japan and Shanghai Jiao Tong University in China studied the serrations on the leading edges of owls’ wings, gaining new insight into how they work to make the bird ...

Aerospace engineers have used studies of birds in flight to further research into improved aerodynamics, the development of shapeshifting wings, how mid-air collisions might be better avoided, and ...

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 ...
