🚨 Why do wind turbine assessments keep passing — while residents keep getting sick?
As someone who works in the acoustic measurement space, this one keeps me up at night.
Here's what the official assessments almost never do:
Measure ground vibration.
Wind turbine foundations drive vibration directly into bedrock. That vibration travels kilometres through solid ground — 10 times more efficiently than through air. And yet not a single planning assessment anywhere in the world requires it to be measured.
The tool they use instead — dB(A) — removes up to 50 dB from low-frequency readings. The exact frequencies wind turbines generate most. A compliant 40 dB(A) reading can mask 70 dB or more on a full unweighted spectrum.
And the buildings? They resonate. Wall panels, floor joists, windows — all excited at their own natural frequencies by ground vibration entering through the foundation. The hum residents hear is being generated inside their own walls. No outdoor microphone can detect it. It's physically impossible.
This is documented in Chapters 7, 8 and 9 of the Stop the Noise free handbook.

Are current measurement standards fit for purpose? I'd genuinely like to hear from engineers and acoustic professionals on this.
