Wind Turbine Noise | TurbineGenerator
Yes, wind turbines generate two types of noise: aerodynamic noise and mechanical noise. The aerodynamic noise is generated from the blades as they pass through the air. The loudness of the aerodynamic noise is related to how fast the tip of the blades are spinning, the size of the blades, and the wind speed.

Ball Milling an overview | ScienceDirect Topics
Ball milling is a mechanical technique that is broadly used to grind powders into fine particles [134141]. The reactants are generally broken apart using solvent molecules in the traditional method; but in ball milling, reactants are broken by using mechanical forces. The term mechanochemistry has been introduced very recently [142].
