Noise complaints lead to monitoring
by Sandy Casselman
BRINSTON – It has been more than six months since the blades of the
South Branch Wind Farm turbines began to spin, leaving more than one
nearby resident with some sleepless nights.
“I call when it gets to the point I can’t tolerate it anymore and I go
to the basement [to sleep],” Brinston resident Leslie Disheau, former
president of the South Branch Wind Opposition Group, said. “It is an
I’m not the only person in town with the issue.”
Disheau, who is running for the Municipality of South Dundas’
deputy-mayor seat in this fall’s municipal election, has been staying
close to home since the Ministry of the Environment (MOE) installed
noise-monitoring equipment at her Brinston Road property last week.
“MOE contacted me and asked if they could put this noise monitoring equipment up,” Disheau said.
The two pieces of equipment measure wind speed and direction, barometric pressure, rainfall, and more, she said.
She has submitted three separate noise complaints so far. Every
complaint must be filed with EDP Renewables’ project leader Ken Little
and local MOE representative Terry Forrester to be officially
During EDP’s first open community liaison meeting in March, a Brinston
man spoke out about his own sleep disturbances, suggesting the turbines
be shut off for a period during the early hours of the morning,
beginning around midnight. At that time, Little confirmed that there
had been one official complaint already registered. He also said an
acoustic audit had been ordered, which he expected to get underway
within two months of the meeting.
“EDP has not released their post-construction noise audit report,”
Disheau said during an interview with the Winchester Press Fri., July
In conversation with one of the MOE officials who installed the
equipment, Disheau said she learned that the provincial authority also
had not seen a report from EDP.
“They can take a long as they want,” she said, crediting the Green
Energy Act with the responsibility for not specifying a deadline.
“There is a 40-decibel limit [on the noise the turbines can make], and
we have no idea if they’re in the threshold or not.”
To describe what the sound is like, she used Highway 401 versus
airplane noise as an example, pointing out that the highway noise is
more of a hum, and when she lived near it, the sounds did not bother
her at all.
However, the turbines produce something more in line with the “drone of
an airplane that goes into your head,” she said. “It’s a deeper tone,
and that’s where you get the disturbance of sleep.”
Explaining the noise and its effects on her is not easy, she said, but
it is similar to the sensation people get in their chest when listening
to bass guitar.
Disheau said she explained her experiences to MOE’s acoustical
engineer, adding that the sensations are at their worst when the blade
tips of the turbine across the road (south of Brinston) and the one to
the north behind her home (west of Brinston) are facing one another.
“The acoustical engineer said ‘yes, that it all makes sense,’” Disheau
added. “This is not normal. You should not be in sleep disturbance in
your own house.”
Meanwhile, Disheau is the only one in her home experiencing the effects
of the rotating blades, as her husband, who shares the second storey
bedroom on the home’s vinyl-sided addition, is tone deaf, and her
children sleep on the first floor of the brick-sided main house.
The noise-monitoring equipment is controlled by a switch, which has
been placed inside Disheau’s home. When she notices the noise, she
flips the switch and the machinery calculates and documents the
“Once everything is taken down, the ministry guy goes through [the
recordings] and writes his report,” she said, which will list the
decibel readings for various weather conditions (wind speed and
When asked what she hopes to accomplish through this procedure, Disheau
said the findings could require that EDP shut down operations during
specific times of the day or during specific wind conditions should
they prove the decibel levels exceed the regulated amount.
