During the summer 2016 infrasound measurement device development proceeded. Mainly algorithm and user interface development were continued. A measurement instrument prototype was completed in early fall, and it was tested in different parts of Finland.
September – October one party in government took people experienced health problems seriously. The case got a lot of attention in the media. In the past people who were suffering health symptoms caused by wind turbines were stamped to be hypochondria by media and that’s why the politicians had not been able to grasp the point. Finnish National Institute for Health and Welfare was also commissioned report of the topic. Wind turbine harm to health was examined, but not any serous investigation was done. The researchers did not measure the infrasound in any point.
Interest aroused from the potential health hazards of infrasounds, I wonder how objective research should be carried out. Since I have been involved in the past in various research projects related to health and technology, I knew that one of the major risk factor is nocebo effect. If the people themselves are able to see in real time the amount of infrasound by using the measuring device, they may experience symptoms seem to get worse at the moment. Therefore it was goal to make a system, where man himself is not accessible from the measured data, but the opening of the data is done elsewhere.
Upon request, I also did research plan to the Ministry and manufactured a number of measurement instruments for the government planned infrasound and health research. We have not heard anything from Ministry, but we started making research anyway, so that the research could be completed in the target timeframe.
Since January 2017 about 20 infrasound measuring devices have been at a time in different parts of Finland about 1-10 kilometers of power stations in homes, where there have been health symptoms which occurred after wind turbines started. Measuring devices have been in same places a one month. At the same time there was filled a daily health symptom diary.
Survey data are unloaded from the raw data and diaries during the spring.
If infrasound caused by wind turbines are reason to people’s sleep and health symptoms, it appears in the investigation we undertook. We will analyze the results when data has been collected enough, we hope to get data from some hundred test persons.
