In this paper, an acoustic detection technology of blade damage based on spectral mutual difference method is pro-posed, which can effectively and accurately identify the damage of wind...
Wind turbine noise is generated aerodynamically by the rotor blades passing through the air as well as mechanically by various components such as nacelle fans and generators.
This study proposes a physics-informed neural network framework for damage detection in wind turbine blades in operational wind farms, leveraging active acoustic excitation and a helical microphone array.
The Blade Barrier was presented on July 2, 2025, as the first noise barrier constructed from discarded wind turbine blades. The 60-meter-long test setup is located along the A58 highway near Oirschot
Wind turbine blades produce airborne pressure waves (correctly called sound but which, when unwanted, is called noise) and ground-borne surface motion (vibration).
This study explores the use of noise emitted during wind turbine operation for the assessment of blade structural integrity.
This paper firstly introduces the existing wind turbine blade detection methods and reviews the research progress and trends of monitoring of wind turbine composite blades based on acoustic signals.
Discover the real sounds of wind turbines. Uncover the truth behind the noise and learn what to expect from these renewable energy giants.
Operating wind turbines can create several types of sounds, including a mechanical hum produced by the generator and a “whooshing” noise produced by the blades moving through the air.
A group of scientists has developed a sensor that can identify potential problems with wind turbine blades using only sound. Two departments from the Fraunhofer Institute developed the unique solution to
