Good listening

Reports of unusual noise from a wind farm come in to our Asset Management Department, aka the management department. These may come from a landowner, a nearby business or a passerby of a wind farm. Consider, for example, a whistling sound or a popping sound. Our managers take every sound seriously to find out if something is wrong. ”It is important to first determine where the noise is coming from, because a small noise can escalate into a bigger problem. We take complaints seriously, listen and try to find a solution,” explains Romana.

Understanding complaints

Noise complaints often stem from specific problems with the turbine. Senne explains that failures in the generator or peeling paint on the blades can lead to distinctive sounds, such as a low hum or whistling. ”The team handles complaints methodically by first analyzing data on the wind turbine that receives a noise complaint and then asking residents or other complainants questions about the noise they hear, its timing and their proximity to the turbine to rule out other possible sources.”

Data-driven analyses

To identify a noise complaint, our team checks the data data for discrepancies. For example, a faulty inverter can reduce the capacity of a turbine, changing the sound. In other cases, a gap between magnets can increase vibrations, producing a sound that spreads far. If the data does not pinpoint the problem, Senne and Romana can make a site visit to assess the sound themselves.

In doing so, Romana stresses the importance of staying in touch with other administrators to exchange noise management strategies. “We hold regular meetings to share our challenges and solutions,” she indicates.

Challenges in managing noise complaints

One of the biggest challenges for Senne and Romana is the subjective perception of sound. People may report that they are bothered by noise, but it may then be the case that Senne and Romana themselves when standing next to the turbine do not hear any noise. With each case, they learn to look beyond the numbers and recognize that noise complaints can be influenced by environmental factors – such as nearby construction activities – or even trends in media coverage, which can increase community sensitivity to turbine noise.

Long-term adjustments and constant improvements

Years of analysis led Senne to call for expanded data access, allowing the team to monitor turbine operation independently of manufacturers. This allows the team to respond more efficiently to potential problems, reducing the turnaround time for resolving complaints.

Despite their efforts, Romana stresses that it is a challenge to satisfy everyone. “We have learned to take every complaint seriously, because things can escalate if nothing is done about it. Even if it is a unique case, we strive to identify the root cause, recognizing that each location and situation has its own nuances,” she says.

As the landscape around wind farms evolves – new residential neighborhoods, seasonal changes in sound perception, and nearby solar farms that alter sound propagation – their work becomes more complex. But with each new case, Senne, Romana and their team improve their ability to ensure minimal noise pollution in the surrounding communities while promoting a more sustainable future through wind energy.
