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. Inspired by this natural ...

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 ...

Modern life is noisy – from the constant hum of traffic to the roar of machinery. But there’s something to learn from nature’s ultimate silent hunter, the owl. Owls are silent flyers because their ...

CHICOPEE, Mass. (WWLP) – You may have noticed lately an increase in owl noises in your backyard or out for a walk… that’s because owls are out looking for a mate! Owls are the most vocal during the ...

CHICOPEE, Mass. (WWLP) – You may have noticed lately an increase in owl noises in your backyard or out for a walk– 22News is working for you with tips on how to spot an owl. A 22News viewer sent a ...

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 ...
