Methods to reduce Low-Frequency Noise of Wind Turbines for the Einstein Telescope — Marc Boxberg2, •Tom Niggemann1, Niklas Nippe1, Achim Stahl1, and Florian Wagner2 — 1III. Physikalisches Institut B RWTH Aachen — 2Geophysical Imaging and Monitoring RWTH Aachen
Seismic vibrations from nearby wind turbines are expected to be a significant noise source in the Einstein Telescope, a future third-generation gravitational wave detector in Europe. Direct and gravitational couplings are a limiting factor for detection of gravitational waves in the low-frequency range. This talk will discuss and evaluate methods to produce less vibrations in the first place and to reduce their coupling to the ground. Measurements of the vibrations from different types of wind turbines will be explicated.
