Both "audible" and "potentially annoying" noise from a wind farm has been confirmed through field data documented under a state-based university study.
The discovery made by a Flinders University research team have found that 'indoor low frequency noise' is present for about 16 per cent of the time at distances up to 3.5km.
Study results form the university's investigations into effects on wind turbine with regards to noise and sleep.
The findings have since reached a group of Keyneton residents who have opposed the wind farm development long before its approval in December 2013.
Apart from being vocal in the development affecting their environment, house and land prices and more, concerned residents also shared concerns over the affects of sound and noise.
Resident David Formby believes these preliminary results continue to help the fight against wind farms from being built. However, he and other residents currently focus their attention on the two-year build work extension, granted by the state's former Planning Minister.
To date, the land earmarked along the Mount Lofty Ranges remains untouched with Victorian developers Pacific Hydro given until December this year to begin construction.
"It (the extension) means the substation and the main part of the wind farm (excluding the completed turbines) is to be built in December," he said.
"I can't see how they can get all that done over the next five to six months."
Meanwhile, the university's research, which describes the noise from a wind farm as 'thumping' or 'rumbling', is technically referred to as amplitude modulation (AM) related to the frequency of turbine blades passing the tower and power outputs of wind turbines.
Leading the university team is Dr Kristy Hansen, who visit Keyneton mid last year and explained AM is one of the most prominent features of wind farm noise so warrants studies into how commonly it occurs, and what impact it has on people.
"In this first study, we found that audible AM decreases with distance from the wind farm but still remained prominent over long distances," Dr Hansen said.

National wind farm commissioner to visit
Amid community angst over both the approved Keyneton wind farm and the proposed Twin Creek development outside Kapunda, national wind farm commissioner Andrew Dyer will visit the state early next month.
While his itinerary is yet to be finalised, last week he told Barossa Herald of his intentions to meet with stakeholders regarding the Twin Creek development with the aim of also meeting Keyneton residents, when he arrives on July 3.
Based in Melbourne, he said his "mixture of meetings" are to coincide with discussions with Flinders University regarding their research, plus talks over developments at Port Augusta and Crystal Brook.
While Mr Dyer understands Keyneton wind farm's two-year build extension lapses this December, he said, "I am not a fan of another extension...yet it is not my decision," he said.
The third National Wind Farm Commissioner annual report was tabled with parliament last week.

Letter to the Editor
The Federal ALP and the Greens dubbed it the "climate election" that we apparently had to have. And thank goodness we did, as millions and millions of the Prime Minister's aptly named 'quiet Australians' voted against nation destroying renewable energy obsessions.
Australians used their power in the ballot box to reject the increasingly shrill cries of world-ending global incineration from those with snouts deep in the green energy trough.
Those quiet Australians rejected massive increases in solar and wind power that would ultimately cost them real jobs that put real food on their tables.
They are just trying to get back to work and live their lives without massive government interference.
Since the election, I'm aware of more and more parents now brave enough to call out and counter the 'climate emergency' fear campaigns that are being shoved down our children's throats in Australian schools, resulting in some students hysterically marching in the streets.
Those students want better weather and they want it now.
They demand an end to the power source that gives them their endless electronic devices, air-conditioned homes and classrooms, televisions, highly advanced medical equipment and cars in which to be chauffeured around in. More comfort than any generation before them yet they're not happy with the weather. Poor little things.
For now, at least, a devastating socialist, green agenda has been put back in its box in many parts of Australia.
No such luck for the Barossa, as the Green Blob marches on.
The nation's rejection of more renewable energy makes the construction of the Keyneton wind power disaster even more tragic.
