Comments by Queensland Government Noise Expert - Dr Antoine David

These documents, secured under the Australian Right to Information (RTI) Act, reveal that warnings from the Queensland Government's own noise expert were not provided to the public or passed on to the Planning Department or the Minister for Planning to inform the wind turbine siting process. Dr Antoine David, the noise expert in the Department of Environment and Heritage Protection provided his superiors with a list of nine points of concern regarding the draft Wind Farm Code. The list of his concerns is provided below and can also be found on page 7 of the attached document. A RTI request revealed that, despite making his concerns known within his department, Dr. David's findings were not forwarded to the Department of Infrastructure, Local Government and Planning, the department responsible for developing the current draft (version 2) of the Wind Farm Code.

Bullet points for Draft Wind Farm State Code acoustics review

  • Acoustics problem associated with wind farms are due to the infrasonic and low frequencies harmonics and their interaction between several turbines. Those generates [sic] 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 of the 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 infrasound effects cannot be assessed by dBA. By designed, 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 state code is 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 state code will protect animals such as farmed animals for their health and well-being from low and infrasonic noise exposure.
