Inspiration from owls' wings could allow aircraft and wind turbines to become quieter, suggests a new study. Researchers studied the serrations in the leading edge of owls' wings, gaining new insight into how they work to make the birds' flight silent. Their results point towards potential mechanisms for noise suppression in wind turbines, aircraft, multi-rotor drones and other machines.
