Wind: it’s the sound you can hear

With concern in the community over thepotential obstruction of wind farms on fire fighting efforts, the latestresearch has emerged to address one of the other major concerns associated withthe turbines – infrasound-related illness.

As long as turbine blades have beenrotating, waves crashing, trains speeding or even air conditioners cooling, peoplehave connected the exposure to inaudible sound with the deterioration ofhealth.

Many believe that infrasound can causesuch symptoms as dizziness, nausea, headaches and insomnia.

Last week, the Victorian Department ofHealth published research into this mystery and concluded that there was noevidence to suggest that low frequency sound waves cause physical illness.

“Humans have been exposed to highlevels of infrasound throughout our evolution, with no apparent effects,”the Health Department review says.

“[The evidence does not] supportclaims that inaudible sounds can have direct physiological effects.

“Physiological effects on humanshave only been detected at levels that are easily audible.”

The review said it was the irritation ofthe audible noise that resulted in stress which, in turn, led to peoplecontracting sleep disorders and other ailments.

A Victorian study found only audible noise could cause irritation, stress and other ailments.
