The Deceit of Turbine Noise Models (collateral damage from government energy forcing)

“When will the environmentalist community writ large wake up to the unintended micro consequences of their increasingly futile macro policy of forced energy transformation?”

Herkimer County, New York, is the latest location to register wind turbine noise complaints. The source? Iberdrola’s Hardscrabble wind facility (37 turbines) that went online earlier this year.

Studies are underway to determine if the project is operating outside legal sound limits, but the larger question is “Why?” Why, with over 1,300 MW of wind installed in New York today and an extensive body of evidence showing turbine noise is causing deleterious impacts on people living near the towers, was Herkimer County fooled into thinking it would be spared?

The answer is simple: Herkimer County residents were lied to.

Yes, we could use softer words to explain the situation. But given what sound experts already know about turbine noise, the time for niceties has passed.

Predicted Turbine Noise at Hardscrabble

Prior to erecting a wind facility, project owners usually engage acoustic engineers to prepare models that predict sound level increases a community can expect from an operating project at certain reference points. These engineers rely on the CADNA/A [1]software tool for their models. CADNA/A is based on ISO 9613-2, the international standard developed for sound prediction. [Read more →]
