Hear the Difference the FeatherEdge® Makes (video)

What makes FeatherEdge turbine blade serration technology so effective in reducing wind turbine noise? In this video, you can can - and hear - the difference!

First, Biome Renewables' Robin Borgert demonstrates the FeatherEdge difference in serration design, shape and materials with Jeferson Marques from Schierloh Engineering

Then, listen to a video sound file that was sourced at 700m distance at the Hamelhausen wind farm, recorded by environmental acoustics firm deBAKOM.

The static you hear is wind noise. With the FeatherEdge, the low frequency rumble and mechanical noise is gone. For experts in wind power noise and production, the difference is startling!
