The studies identified a direct causal link between wind turbine infrasound and low frequency noise and neighbours’ health problems including sleep disturbance, collectively described as “annoyance”. The research was presented at the American Wind Energy Association conference in California in 1987. 

The wind industry, specifically wind turbine manufacturers and wind developers, therefore knew about the direct causal relationship between these specific sound frequencies and health damaging“annoyance” symptoms, which included repetitive sleep disturbance.

Not only does this body of research clearly identify infrasound and low frequency noise (ILFN) as the direct causal agent, at levels well BELOW the threshold of audible perception, but it also nominates evidence based maximum tolerable noise limits in the ILFN frequency range the
researchers considered necessary to protect health, based on their field data.


The subsequent failure by the wind industry and government noise pollution authorities to ensure these health protective guidelines were incorporated into wind turbine noise pollution regulations,and then properly monitored and enforced, has directly resulted in the serious harm to the health of thousands of rural residents around the world. The harm is now predictably increasing, as the size of the wind turbines increases.

This is a global disgrace.

This has happened because wind turbine product manufacturers have failed to present the truth about the existence and cause of adverse health impacts known to them for nearly thirty years from Dr Kelley’s research. Wind industry excuses that the research “did not apply to modern upwind turbines” have been dismissed by Dr Kelley, a view supported by the growing number of concerned senior acousticians such as Dr Paul Schomer, current Director of Acoustic Standards in theUSA.


Furthermore the acoustic field research findings of a growing number of independent acousticians working in Australia, and North America are entirely consistent with Kelley’s work. 



Who Needs to Consider Their Part in This Extraordinary Failure ?

Acoustic engineers working with the wind industry have failed to abide by their professional codes of conduct to place the protection of the health of the community above commercial interests.

Acoustic engineers who advised or wrote the government wind turbine noise pollution guidelines subsequent to the Kelley research, ensured that the very sound frequencies below 200 Hz known in 1985 to cause adverse health effects and symptoms known as “annoyance” were not included, and were never measured.

Government bureaucracies including departments of health, planning and noise pollution have consistently failed to protect the health of residents, and failed to investigate and act when serious health problems including exhaustion, and home abandonment were reported by residents and their health practitioners. The first medical practitioner to report health problems to the authorities in Australia was Dr David Iser, in 2004.


RECOMMENDATIONS
1. The Kelley evidence-based health protective criteria for wind turbine noise in the infrasound and low frequency noise range must be immediately implemented, monitored and actively enforced, with priority attention to those residents who are reporting serious harm to health and sleep.


2. Those guidelines will require ongoing field research as they may prove insufficient to protect health, especially as wind turbine size increases, and the numbers of turbines per development increase the cumulative impact and the extent of the project footprint.


3. Acoustic models and acoustic standards MUST be regularly updated to reflect the latest developments in knowledge about infrasound and low frequency noise attenuation, and new dose response information relating to adverse health impacts resulting from chronic exposure.


4. Multidisciplinary acoustic and physiological research must be urgently conducted in order to determine the acoustic and perception thresholds at which sleep disturbance is occurring, with particular reference to residents “sensitized” to the sound energy with chronic exposure.
