Aerodynamic Wind Turbine Emissions and Vestibulo-Cochlear Coupling: Impulsive Pressure Signatures and Their Health Relevance

Abstract: Wind turbine emissions are commonly interpreted within a classical acoustic framework, extending sound-based concepts into the infrasonic range. This study reframes wind turbine emissions as the result of discrete aerodynamic events rather than harmonic sound generation. Rotor-induced flow modulation produces temporally structured, non-harmonic pressure impulses whose periodic repetition yields spectral components without implying oscillatory behavior. These impulse-dominated signals form characteristic wind turbine emission signatures (WTES). Due to their temporal structure and low-frequency pressure gradients, WTES preferentially interact with the . . .
