You might want to reconsider having a turbine as your neighbour with new research revealing the level of noise wind farms make at night.
Electricity isn’t the only thing wind turbines are generating with concerns that the renewable energy source could trigger noise complaints.
Researchers from Flinders University are looking for ways to decrease wind turbine noise by improving their manufacturing guidelines and design.
The ‘swoosh’ sound – technically known as amplitude modulation (AM) – from turbines is likely to be heard by neighbouring residents up to five times more in the night than during the day.
Wind direction, season and wind farm distance are all contributing factors to the level of noise generated.
PhD candidate Duc Phuc Nguyen and acoustic expert Dr Kristy Hansen used a combination of long-term monitoring and machine learning to determine the characteristics that contribute to the noise pollution.
“The noise seems to worsen after sunset when amplitude modulation can be detected for up to 60% of the night-time at distances around 1 km from a wind farm,” Nguyen says.
“At greater than 3 km, amplitude modulation also occurs for up to 30% of the night-time.”
Wind Farm Noise Study
The Wind Farm Noise Study which is based at the Adelaide Institute for Sleep health at Flinders University is investigating the repercussions of wind farm noise on sleep disturbances.
According to Dr Hansen, the directional nature of wind turbine noise affects residents in downwind and crosswind conditions.
“Using these recent advances in machine learning, we have been able to develop an AM detection method that has a predictive power close to the practical limit set by a human listener”.
“These studies advance our ability to measure and monitor the noise from wind turbines that is likely to be more annoying than other noise types at the same level.”
So if you’re one who likes their sleep, you might want to consider setting up camp next to some quieter neighbours.

Zelensky addresses the U.N. as protests break out in Russia
Zelensky addresses the U.N. as protests over Putin’s mobilisation plan break out in Russia
Ukrainian President Volodymyr Zelensky addresses the U.N. General Assembly in New York.
Zelensky says his nation just wants peace and believes Russia should be punished and ostracised for its actions.
“A crime has been committed against Ukraine and we demand just punishment. The crime was committed against our state borders. The crime was committed against the lives of our people,” Zelensky said. “Ukraine demands punishment for trying to steal our territory”.
In the powerful speech, the Ukrainian President also called for Russia to lose its U.N. veto power. Russia is currently one of the five permanent members of the Security Council.
He is also seeking more military aid, pleading for more weapons to help liberate his country’s land.
Protests engulf major Russia cities
In Russia, police have arrested hundreds of protestors who are rallying against Vladimir Putin’s military mobilisation.
Human rights group OVD Info estimates more than 1,000 people have been taken into custody so far. The largest number of arrests were made in St Petersburg and Moscow.
As the Kremlin announced its intention to call up thousands of extra troops to fight the warn in Ukraine, flights departing Russia sold out almost immediately.
The mobilisation will likely see at least 300,000 military reservists drafted to bolster Russia’s forces.
In Moscow, the prosecutor’s office is warning that calls on the internet to join protests, or participation in these protests, could result in up to 15 years in jail time.
Russia’s disinformation laws about the war have made public demonstrations rare.
In his first national televised address since the war began, Putin said he will use “all available means” to protect Russian territory.
In theory, this could include nuclear weapons.
NATO Secretary General Jens Stoltenberg says the alliance remains vigilant.
“We will make sure that there is no misunderstanding in Moscow about exactly how we will react. Of course it depends upon what kind of situation or what kind or weapons they may use. The most important thing is to prevent that from happening and that is why we have been so clear in our communications with Russia about the unprecedented consequences,” Stoltenberg said.
Meanwhile, Putin’s mobilisation follows weeks of heavy losses for Russia in Ukraine, with Kyiv recapturing a huge area just east of Kharkiv.
U.S. to provide Ukraine with tanks in the future
U.S. to provide Ukraine with tanks in the future, but there is a catch
The U.S. will provide tanks to Ukraine in the future, but issues with maintenance and training may delay the rollout.
Ukraine has received billions of dollars worth of weapons and military equipment, allowing the war-torn nation to defend itself against Putin’s regime.
Russian forces are continuing to “conduct airstrikes that are impacting civilian infrastructure”, most recently striking a “dam near Kryvyi Rih”, according to a top U.S. official.
“This disturbing pattern which includes strikes that hit power stations last week continues to show Russian forces’ disregard for civilian life,” the official added.
When it comes to further military aid, the offical confirmed tanks are “absolutely on the table”, but are not an option for the immediate battle.
Once training, maintenance and sustainment issues are addressed, the roll out is more likely.

Mass burial site discovered in Ukraine
A mass grave with over 400 bodies has been found in Ukraine’s Kharkiv region
The price of war is beginning to reveal itself in Ukraine as a mass grave, with over 400 bodies has been discovered in the recently liberated Kharkiv region.
The burial site was found in the city of Izyum, an area captured by Russian forces at the beginning of the war, and a victim to ultimate brutality.
Over recent days, Ukrainian forces have recaptured the area. So far, they have discovered over 1000 bodies in the city, with this number rising every day.
The mass grave site shows the extent of Russia’s atrocities, although Russia denies responsibility.
Ukrainian President Volodymyr Zelensky is launching an investigation and says “Russia leaves death everywhere and it must be held accountable for that.”
