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 ...

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 ...

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 ...

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 ...

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 ...

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 ...
