Lower noise and more energy
for a more sustainable future
The problem of turbulence-induced noise
Turbulence-induced noise is the dominant contributor to noise pollution in wind energy production
Turbulent-boundary-layer trailing-edge (TBL-TE) noise is the single largest source of audible noise
Current blades and add-ons are not optimized for maximum noise abatement
Meet MuteSkin®
Our technology reduces overall blade noise by 6 dB(A) compared to untreated blades. We develop blade add-ons with anisotropic permeability that reduce turbulent-boundary-layer trailing-edge noise. Designs are unique to specific turbines and environments. Lower noise and increase your annual energy production (AEP), for a more sustainable future.
Key benefits
A low-cost worry-free approach to wind turbine noise abatement


Our add-on is passive, it just works. There is no energy expenditure and it has zero moving parts. It is inherently light, simple, and cheap

AEP increase

The substantially lower turbine noise allows for more continuous energy production at noise-constrained sites for the same turbine

Low maintenance

Our add-ons are simple, making them compatible with standard cleaning and maintenance procedures


The technology can easily be retrofitted to existing blades in order to obtain significant noise abatement

Low impact

We strive for recyclability in materials and manufacturing to ensure that the add-ons are fit for the circular economy of the future


The add-ons have a performance superior to all types of serrations, reaching reductions of up to 12 dB in the lab

Noise pollution is straining society
MuteSkin® has benefits beyond wind turbine noise reduction. A variety of high-tech industries are struggling with noise pollution and will benefit from our technologies
Aviation - Trailing-edge noise from the wings in high-lift configuration is one of the major noise sources during landing
Ventilation - Modern buildings and vehicles rely more and more on mechanical ventilation, spurred further by the COVID-19 pandemic. Noise is a determining comfort factor
Drones - Noise pollution is one of the key challenges for the broad adoption of many use cases for drones in urban areas
The team is based at Delft University of Technology. Our vision is to have improved the lives of 10,000 people living close to 100 onshore wind turbines by 2024.
