Noise level measurement
In Finland, Health Inspector Harri Julkunen's meter can measure noise levels, but a major problem is not the level, but the frequencies of noise.

A bombshell from Australia

Governments, scientists, and the wind industry knew!
They have been covering up for 25 years

“It (the 1987 report) found that the standard A-weighted measure for sound was "not an adequate indicator of annoyance when low frequencies are dominant".

“Wind health groups in the US and Australia said although modern wind turbines were different to the one studied, the 1987 research was significant because (modern) industry noise-testing regulations had been specifically designed to exclude testing inside buildings and did not concentrate on low-frequency noise -- the two main issues identified in the report.

“A federal (Australian) Senate inquiry recommended two years ago that in-house testing be conducted in Australia but it is not included in the present noise guidelines.

“... other (modern) research has shown that as wind turbines get larger, a greater proportion of the sound is emitted in the lower frequency range.”

You may download the 1987 report by clicking "here" in the third paragraph of the text at Wind Turbine Syndrome. We recommend you read the summary and the first and last chapters. From page 3 and the references it is clear there are many people, government, corporations and university institutions who know about this research.

The "dose response" protection criteria recommended in this report may not be nearly enough for much larger modern turbines. The limits need to be revised, taking into account the sensitisation* issue with chronic exposure (which they also clearly acknowledged 25 years ago).

* sensitisation: contrary to what governments and industry pretend, one does not get used to ILFN (infrasound and low frequency noise). On the contrary, the longer the exposure, the more one becomes sensitive, and the worse the effects on one's health.
