Acoustic Profiling of Infrasound and Audible Emissions from Wind Turbines: Field Measurements in Northern Sweden #SWE

Wind turbines produce both audible noise and low-frequency infrasound (below 20 Hz), which, though often inaudible, may have physiological and psychological effects that require further investigation. Previous studies confirm that wind turbines are significant sources of both audible and infrasonic noise. Infrasound is primarily generated by blade-tower interactions and atmospheric turbulence. Sugimoto et al. demonstrated a strong correlation between infrasound levels and rotor speed, highlighting the need for sensitive measurement systems capable of detecting frequencies below 1 Hz.
