Case Studies

  • Wind Turbine Noise Amplitude Modulation

    Amplitude Modulation (AM) relates to the varying characteristic of wind turbine noise which means that it can cause more annoyance than constant, stable noise of a similar level. Xi offer a service for the measurement and rating of AM and have a wealth of experience in making recommendations and designing solutions for noise and vibration issues in the renewables sector.
