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 ...

Space to play or pause, M to mute, left and right arrows to seek, up and down arrows for volume. Robyn Williams: So why watch birds? Answer, they can help you with engineering. That's why Dr Nigel ...

Many species of owl are able to hunt in effective silence by suppressing their noise at sound frequencies above 1.6 kilohertz (kHz) - over the range to which human hearing is most sensitive. A team of ...

Frequent reports of turbulence are scaring many air passengers away from flying. The increasing regularity of turbulence is being attributed at least partially to climate change. Aviation engineers ...

The serrated edge of owl wings, which help the birds swoop down stealthily on unsuspecting prey, can help inform better designs that cut noise from aeronautical and turbine engines, according to a new ...

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 ...

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 ...

Scientists have developed a new material to make aircraft and wind turbines quieter by mimicking the design of owls' wings that allows them to silently hunt their prey. The team at Cambridge ...

Many species of owl are able to hunt in effective silence by suppressing their noise at sound frequencies above 1.6 kilohertz (kHz) - over the range that can be heard by humans. A team of researchers ...
