Wind Turbine Noise Emission Warranties

Wind energy is one of the cleanest energy production methods available. However, wind farms are increasingly being installed closer to urban and residential areas, leading to noise concerns. Under the environmental noise regulations, wind farms are classified as industrial noise sources, making source-level noise control essential.
While environmental noise control methods can be applied to wind turbines, manufacturers also bear responsibility. Environmental noise is considered a pollutant from an environmental protection perspective and requires source-level control.
The foundation of source-level noise control in wind turbines lies in limiting aerodynamic and mechanical noise. For this reason, manufacturers are required to provide noise emission warranties—a practice common in global markets, especially in countries with high noise sensitivity. These guarantees are based on noise limits defined by national regulations and encourage manufacturers to produce quieter turbines.
At Spektre™, we provide consultancy services to wind energy investors to ensure noise control in compliance with international and local standards. We communicate directly with turbine manufacturers to deliver solutions aligned with local regulations and prioritize human health and comfort. Our services include identifying noise-sensitive structures, determining environmental noise limits, and collaborating with energy investors to guarantee accurate parameters such as broadband sound power level, narrowband tonality, impulsiveness, and amplitude modulation based on wind speed ranges. We also offer test planning services for post-installation measurements of wind farms.
For international projects, we adapt warranty and testing procedures to local regulations and global best practices.
