As the global transition to revolable energy accelerates, wind power has establice a cornerstone of sustainable electricity generation. However, the explosion of wind farms has inputed a complex environmental concern: noise pollution and it effect on local wildlife. While wind turines produce difficiantly less noise than conventionale power plants, the sounds they generate can travel across landescapes and interact with animaid ways thathates chere still working.

Wind farm noise is not merely an acoustic nuisance; it can alter thee ecological dynamics of an area. Animals rely on sound for communication, vigation, predacor decognition, and foraging.
