Preliminary Measurements and Research Agenda
As part of an ongoing research project, we conducted preliminary infrasound measurements at several Swedish wind farms. The objective was to evaluate variations in the infrasound signal between wind turbine operational and shutdown modes and to identify differences between infrasound levels measured near wind farms and at reference locations unaffected by wind turbine emissions. This article summarises early observations, outlines the analytical approach, and presents a research agenda for future work.

The context for this research is the ongoing energy transition and the trend towards repowering with increasingly tall turbines, with total heights approaching 300 metres under discussion. These developments raise new questions regarding infrasound propagation, nocturnal enhancement under stable atmospheric conditions, and the nature of exposure experienced in and around dwellings.
