Bullet points for Draft Wind Farm State Code acoustics review 

Author:  | Australia, Health, Noise, Regulations

  • Acoustics problem[s] associated with wind-farms are due to the infrasonic and low frequencies harmonics and their interaction between several turbines. Those generate[] annoyances and to higher intensities health effects.
  • By using both a time average and frequency weighting, by definition, all those harmonics disappear and as such no assessments ofthe impact of those harmonics can be made.
  • To assess those harmonics, it is necessary to use unfiltered data and no time average.
  • The low frequencies and infrasmmd effects cannot be assessed by dBA. By design[], the A filtering process takes away low frequency and infrasound. Low frequencies and infrasound need to be assessed by dBlin which is unfiltered data according to frequency.
  • Annoyance has not been considered in either guideline[.]
  • Wind masking has been applied as if it was masking noise of similar frequencies[,] and this is not the case.
  • The distance of 1500m as a buffer will not be sufficient for the current size of wind turbine. This distance had originated years ago for much smaller size turbines and at the time was probably a correct distance.
  • The noise criteria proposed in the draft wind farm s[t]ate code [will] most likely not protect residents for their health and well-being and will not protect their environmental values.
  • It is uncertain and unlikely that the noise criteria proposed in the draft wind farm s[t]ate code will protect animals such as farmed animals for their health and well-being from low and infrasonic noise exposure.

We have reviewed the draft code (noting that it is based on independent technical advice) and have no concerns.

I also have been asked to prepare a response to this letter. Lawrie Wade tells me there was a previous letter stating out position that wind farms should not be an ERA. The reply letter needs to restate out opposition to Wind Farms being an ERA.
