"Australian scientists have shown that the infrasound generated by wind
turbines does not make people dizzy or nauseous, does not affect heart health
or mental health, or affect sleep.

Scientists recreated the infrasound of wind turbines and played them through
speakers to 37 volunteers in a sleep laboratory. Others were subjected to “sham
infrasound”, by sleeping near the same speakers as they emitted no infrasound.

The sleep volunteers were also exposed to normal overnight ambient noises, such
that from traffic and trains.

The researchers from the Woolcock Institute of Medical Research, which
specialises in studying sleeping disorders, monitored the subjects as they
slept and ran tests after they woke.

“We detected no effect of three days of infrasound exposure on all the health
variables that we measure – sleep, blood pressure, balance, hearing, that sort
of thing,” said the study’s lead researcher, Professor Ron Grunstein."
