 Context examples 

Their results point towards potential mechanisms for noise suppression in wind turbines, aircraft, multi-rotor drones and other machines.

(Owls' Wings Key to Beating Wind Turbine Noise, The Titi Tudorancea Bulletin)

These owl-inspired leading edge serrations, if applied to wind turbine blades, aircraft wings or drone rotors, could provide a useful biomimetic design for flow control and noise reduction.
