Q: Do wind turbines make a lot of noise?
A: Because wind turbines are machines that have moving parts inside and out, they will make some sound. Nevertheless, many modern wind turbines operate quietly and smoothly. Wind Unites Us makes sure that issues like this are assessed so that they will not significantly affect residences. We do this by using state-of-the-art modern wind turbine technology that can help lessen possible problems with noise.
Q: What do low frequency and infrasound mean? How does it affect human health?
A: If the sound has a range of 20 to 200 hertz, it is considered low frequency. Infrasound, on the other hand, has a range of less than 20 hertz. These sounds are believed to be a combination of hearing and tactile sensations which are natural or made by humans. Examples of natural sources are waves or simply the climate. Low-frequency sounds are caused by sounds from heavy equipment or household appliances. Every day, humans are exposed to these sound ranges.
Modern wind turbines and other sources emit infrasound. Nevertheless, this should not be an issue because these sounds are not perceptible to humans. There is also no scientific proof that unperceived infrasound can cause psychological or physiological problems. Moreover, studies and field measurements conducted on wind farms show that infrasound is barely perceptible if wind turbines are built at a distance greater than 100 meters. Put simply, there is no reason to say that infrasound can cause harm to residents.
