Increasing research into possible health effects from the operation and expansion of wind turbines - The motion of Dr. Bernd gap (Printed Matter VI - 106) will be Transferred for Further consideration to the Executive Board of the German Medical Association ]

The motion of Dr. Bernd gap (printed matter VI - 106) will be transferred for further consideration to the Executive Board of the German Medical Association:

The wind energy as a renewable forms of energy will be used more in future. This is social consensus after decided in summer 2011 nuclear phase-out. The abandonment of nuclear energy shows that problematic aspects of the use have been moved in the future; To date, the issue of the disposal of fuel rods is not really solved. With regard to renewable forms of energy should the entire life cycle of these technologies from the initial raw material supply to disposal in the planning and risk considerations are incorporated in advance. This requires scientifically sound findings on potential health effects in order to make a conscious balance between benefit and reasonability of valid impairments and risks. In particular for emissions in the low frequency and infrasound range, there are no reliable independent studies that investigate suitable for this sound field measurement methodology, the effects below the hearing threshold. Thus, a wholesomeness that noise pollution has not been established at present.

The 118th German Medical Assembly in 2015 therefore calls for the federal government to close the gaps in knowledge about the health effects of infrasound and low frequency sound from wind turbines (WEA) through scientific research and to clarify open questions in the field of measurement methods and, where appropriate, adjust regulations to allow the expansion and the operation of wind turbines wisely, can be carried out carefully, holistic expertise, sustainability and overall social responsibility.

Reason:

Particularly in the health effects of infrasound (<20 Hz) and low-frequency sound (<100 Hz) are by emissions and emissions from wind turbines still open questions, such. As to the effect of noise below the hearing threshold or lower frequencies with increasing exposure duration. Furthermore, a need for adjustment in measuring methods and regulations should be checked for. As on the portability of radiation and propagation models for smaller wind turbines on large systems as well as binding rules of measurement and evaluation of low frequencies (0.1 to 20 Hz).

Core objectives:

  • Systematic, transparent, open-ended, empirical research of PERMEANT in the human body low frequency range
  • Networking with have long been searching in this field abroad groups
  • Continuous publication of the results, the research methodology to approach a stop expansion of settlements, pending sufficiently reliable data, which exclude a hazard safely.
  • In the distance problems, the noise and the shadows the wind turbine positions for settlement depending on the topographical condition, the main wind direction and the sun's rays have to be considered in addition to the installation height as well. If for example a wind turbine park on the wind- and sun-facing side before a settlement, so sound propagation and shadows of the settlement will be disturbing, as if the wind farm is behind this settlement.
  • A need of reform technical guidance on Noise (TA-Lärm), which protects only insufficient, can not continue to be used as a protective provision.
  • The resulting sound research initiated plays at all levels of sound exposure a health protective role, not only in wind turbines.
  • Also important is the study of structure-borne sound (= low-frequency solid vibrations from 100 Hz to 0.1 Hz), which emanates equally dangerous in the form of the modern wind turbines.
  • Structure-borne sound also arises already when the rotors of wind turbines not yet running, but due to the bending vibrations of extremely high wind turbine towers. It is transferred over the foundations in the ground environment. Depending on the topological and geomorpher situation (soil layers) at the location of such facilities, the structure-borne sound can be readily up to 10 km and be registered as immission in the housing development. Here to view the infrasound (airside) only sole and investigate, is thus not sufficient to bring explainable and useful findings.
  • Therefore, should the framework of measurements to assess the health risk of the future always in addition to the external measurements and internal measurements are carried out in the houses (instead of the usual practice here of acoustic calculations).
  • The interactions of structure-borne noise and air infrasound can enable the detection threshold of affected people has come down significantly. Health problems of these individuals may therefore occur even at very low levels.
