How Noisy Are Wind Energy Generation?

As the world searches for clean energy solutions, wind energy is one of the popular choices due to its renewable potential and large-scale generation.

However, wind turbines produce noise levels. In this blog post, we’ll explore the levels of noise produced by wind turbines and how.

In this video, you can see how a wind turbine’s noise level varies with distance from the source.

Wind turbine's noise level

Within 100 meters of the wind turbine, the noise level is equivalent to 105 decibels from a tractor and 50 decibels from an air conditioner.

At a distance of 300-400 meters, the noise level is comparable to 40 decibels emitted by a refrigerator at work.

Sounds below 40 decibels are like the sound of our pet (cat or dog) sleeping outside the door.

The impact on our daily life is almost zero.

Wind energy system noise

How does the wind energy generator noise come about?

Wind turbine noise is produced by a combination of factors.

Including the aerodynamic noise of the blades as they spin through the air.

It also includes mechanical noise from the generator and gearbox and noise from the supporting structure.

Wind turbine noise is also affected by wind speed and direction.

As well as atmospheric conditions such as humidity and temperature.

How to reduce wind turbine noise?

The following method is PVMARS through technological innovation, thus reducing wind turbine noise.

1- Use larger blades that spin slower. This reduces aerodynamic noise.

2- Use different materials for the blades and support structures to reduce mechanical noise.

3- Improved design of the gearbox and generator to reduce noise levels.

PVMARS has different types of wind turbines.

Including the vertical and horizontal best-selling models, and the vertical wind turbine is the first choice for quiet users.

For example, this case also uses vertical wind energy and solar energy. Click on this article to learn more.

Conclusion

Wind turbines produce noise depending on the distance from the sound source.

However, its noise is comparable to everyday appliances such as air conditioners and refrigerators.

While efforts have been made to reduce noise levels, it is also imperative to consider the potential impact on nearby communities when placing wind turbines.

Wind energy is still a promising clean energy source for the future.
