Blade Noise Control

Home / Blade Noise Control

Situation for wind farm operators

Limited Site Selection

Regulation on noise levels reduces the availability of sites suitable for wind turbine installations.


Higher Product Cost

The increase of noise due to larger blades requires add-ons to series production, like vortex generators.


Noise Curtailment

The energy yield of a wind turbine is sacrificed in order to reduce noise during operation.



With Blade Noise Control, we provide a tool to minimize the negative impact of blade noise both on efficiency and on the environment.


Features of Blade Noise Control

Passive Noise - Reduction

Identifying the sources of noise leads to better wind turbine and blade designs.


Active Noise - Reduction

Dynamically maximized energy-to-noise ratio optimizes the possible energy yield.


Curtailment management

With actual and ongoing noise measurements, operating restrictions can be reduced and yield increased.
