When an engineer tested the number of “teeth” in the comb on the wing of a Eurasian eagle-owl like Flaco, he found it has a number that effectively reduces turbulence.

Owls produce negligible noise while flying. While many studies have linked the micro-fringes in owl wings to their silent flight, the exact mechanisms have been unclear. Now, a team of researchers ...

The owl's legs are similarly covered for the same reason. The broad wings allow owls to flap less and glide more. Gliding is silent. Gliding is often the final step in prey capture.

Owl wing-inspired design reduces noise from aircraft engines, study finds Owls produce about 18 decibels less noise than other birds at similar flight speeds due to wing design Vishwam Sankaran ...

Many owl species have developed specialized plumage to effectively eliminate the aerodynamic noise from their wings – allowing them to hunt and capture their prey in silence.

It isn’t just wing proportion that allows owls to move silently. They evolved to have special feather structures that dampen sound. As Audubon magazine explains, the leading edges of owl wing ...

Owl-inspired material to reduce wind turbine noise By Darren Quick June 22, 2015 Researchers have mimicked the structure of owl wings, which enables them to fly almost silently Shutterstock View 2 ...
