Although wind turbines do produce a constant sound of “noise,” modern models are relatively quiet and often get lost in the background noise. In fact, a working wind farm at a distance of 230-300 meters is no louder than a kitchen refrigerator. Most wind turbines are designed in such a way that the turbine itself is located on the windward side of the tower, which reduces low-frequency and impulsive sounds.
On average, industrial-scale onshore wind turbines produce sounds in the range of 35-45 dB when heard from a distance of 300 meters (For example, the sound from a lawn mower reaches 105 dB, a vacuum cleaner – 80 dB, a refrigerator – 40 dB). According to national legislation, the minimum distance to the nearest settlement where a wind farm can be built is 700 meters (in Europe – 1 km). At this distance, the noise from wind farms is completely absent, and even more so in mountainous areas where settlements are located in lowlands. By the way, according to According to the World Health Organization, the safe noise level for human hearing from wind turbines during the daytime reaches 45 dB and at night 35 dB, which is a guideline for wind power equipment manufacturers.
Low-frequency sounds or infrasounds: The main cause of this syndrome is the so-called infrasound, which is below 20 Hz. It is mistakenly believed that such sounds have a negative impact on health, causing headaches, dizziness, nausea, or stress. But according to research this statement is false, as such sounds are masked by other sounds and the human body does not perceive them at all.
