Infrasound microphone network to monitor wind farm emissions
Abstract:
Infrasound measurements have evolved from simply identifying sources to analyzing key parameters such as intensity, frequency content, and propagation characteristics in various environments. This study focuses on infrasound emissions generated by wind turbines and presents measurements from three wind farms using a synchronized network of four infrasound microphones. The methodology enables detailed analysis of spatial and temporal variations in infrasound propagation under different operational conditions. Our findings highlight the prominent frequency range of 2–10 Hz, where turbine-generated infrasound is most significant, and reveal spatial variability influenced by turbine layout, environmental factors, and geography. By introducing a synchronized, distributed sensor network, this study provides a tool for gaining new insights into the propagation patterns of infrasound and their potential environmental impacts, offering a robust foundation for optimizing wind farm design and mitigating noise-related concerns.
