Bats rely on echolocation for navigation, hunting, and communication, making them uniquely vulnerable to anthropogenic noise pollution that disrupts these vital biological systems.
Individual bats affected by noise pollution experience impaired ability to hunt effectively, navigate safely, and communicate with conspecifics. Bats near noisy urban environments show elevated stress hormones, disrupted sleep-wake cycles, and reduced foraging success. Wind turbine barotrauma - internal hemorrhaging caused by pressure changes near spinning blades - is a painful death. Disease-affected bats suffering from white-nose syndrome experience a prolonged, debilitating illness. These welfare impacts occur across billions of individuals worldwide.
