6 FAQs about [Wind power generation noise distance]

How does wind turbine noise affect power generation?

In practice, wind turbine noise levels are typically controlled by operational restrictions, such as low-noise modes, that limit the power generation and, hence, of revenue. A decrease of a single decibel in a usual wind turbine noise signature is expected to enable an increase in power generation by 2% to 4% .

How noisy are wind turbines?

But some complaints have been made that they can cause too much noise for residents living within a mile of the blades. So just how noisy are these turbines? The closest that a wind turbine is typically placed to a home is 300 meters or more. At that distance, a turbine will have a sound pressure level of 43 decibels.

What factors influence residential noise exposure from wind turbines?

One of the most important factors influencing residential noise exposure from wind turbines is the distance of the wind turbine from the observer 33. For example, at a distance of 120–500 m, the measured turbine noise levels decreased by 3–5 dB (LAeq), while at a distance of 1000 m the noise was reduced by 6–7 dB (LAeq) 34.

Should wind turbine noise be considered when designing a wind turbine?

Solving the issues associated with wind turbine noise generation will go a long way in promoting wind as one of the alternative energy generation technologies. Noise should be considered when designing any wind turbine, specifically low frequency noise related to RPM and airfoil selection.

How is wind turbine noise measured?

Nowadays, wind turbine noise is typically assessed using classical indicators that describe the sound exposure in a general and highly averaged way , , such as the equivalent continuous A-weighted sound pressure level ( L p,A,eq ) .

Does atmospheric condition affect wind turbine noise propagation?

As a summary of the wind turbine noise propagation study, the influence of atmospheric condition for wind turbine noise propagation is listed below: Sound waves go through local upward and downward refracting regions, as a result of the wake deficit behind a wind turbine.
