Characterizing tonal amplitude modulation of wind farm noise

Author:  Nguyen, Duc-Phuc; Hansen, Kristy; and Zajamsek, Branko

[ABSTRACT] In addition to the overall noise level, periodic variations in the loudness of wind turbine noise, known as Amplitude Modulation (AM), also significantly contribute to the annoyance experienced by residents living near wind farms. Due to the high dependence of AM on meteorological conditions and the type of wind turbines, the level and duration of AM are hard to predict. These characteristics have an important impact on the annoyance response of residents. The level of annoyance is expected to depend on the AM depth, the number of AM occurrences and the AM continuity. The aim of this paper is to investigate AM characteristics in the vicinity of two wind farms in South Australia. It has been found that to successfully quantify tonal AM based on the Reference Method proposed by the UK Institute of Acoustics, removing the A-weighting, changing the range of band-pass filter frequency and reducing the prominence ratio are also necessary. AM density at night-time is much higher than at day time (25% versus 15%). However, there is not significant difference between AM depth at night-time and day time. Furthermore, AM is more likely to occur when the wind turbines are operating significantly below their maximum rated power.

Severe localised grain production losses from atypical frosts in the Marrabel Valley Catchment 2011–2014

Author:  Faint, John; and Morris, Mary

For the four cropping seasons from 2011- 2014, a majority of farmers in the Marrabel Valley have experienced unprecedented and widespread frost damage of grain crops on sloping paddocks high above the valley floor. Historically these areas have not been affected by frost as the steep slope of the valley sides ensures that cold air flows towards the lower lying areas where it is normal for frost to form.

The onset of these seasons of atypical and the abnormal frosts and frost damage coincides with the commencement of operation of an 18 km long wind farm which is located on a central ridgeline in the clearly defined catchment area. Four contiguous years of significant production losses have prompted this call for an investigation into whether the wind farm is affecting the near surface meteorology of the Marrabel Catchment. This Catchment covers 21,392 hectares and contains some of the most highly productive and high value cropping land in South Australia, consequently further investigation is justified.

[Submitted to the South Australian Grains Industry Trust (SAGIT), February 2015, as part of a researchapplication, which was not funded. Atypical frosts have continued to occur with millions of dollars worth of damage every year.]

Summary of the Effect of the Medical and Scientific Evidence

Author:  White, Richard; and Bean, Katherine

On our analysis, a number of propositions emerge from the medical and scientific evidence. Some of those propositions had unanimous support by the relevant experts, and others had the support of most.

The propositions which we understand have unanimous support from the relevant experts or are not contested include the following:

We consider that the evidence justifies the following conclusions:

Case Report: Cross-Sensitisation to Infrasound and Low Frequency Noise

Author:  Rapley, Bruce; Bakker, Huub; Alves-Pereira, Mariana; and Summers, Rachel

Abstract – This Case Report describes an episode experienced by two noise-sensitised individuals during a field trip. Exposed to residential infrasound and low frequency noise due to coal mining activities, the subjects reacted suddenly, strongly and unexpectedly to pressure pulses generated by a wind farm located at a different town, approximately 160km by road from their residence. Simultaneous physiological data obtained in one subject and subjective sensations occurring during the episode are reported. Acoustical evaluations of the location of the episode are also reported. The possibility of a nocebo effect as an etiological factor for their bodily reactions is cogently eliminated.
