Potential relief for those living near wind farms:

wind-turbines

Owl-inspired wing design reduces wind turbine noise by 10 decibels.  Some people living near wind farms have complained about health problems caused by the turbine noise.  While the debate continues as to whether the noise adversely affects human health, relief may be on its way.  Science Daily reports that a team of researchers studying the acoustics of owl flight have been working on pinpointing the mechanisms used by many species of owl that allows them “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.”  The researchers wanted to use those mechanisms “to improve human-made aerodynamic design — of wind turbines, aircraft, naval ships and, even, automobiles”  And apparently they have succeeded in using owl feathers “as a model to inspire the design of a 3-D printed, wing attachment that reduces wind turbine noise by a remarkable 10 decibels — without impacting aerodynamics.”
