This paper investigates the relationship between gravitational wave energy and metric affineness in active gravitational fields. We present a novel analysis of gravitational wave behavior when propagating through regions of varying energy density. Our findings suggest a significant correlation between metric variations and gravitational wave energy attenuation, particularly in regions characterized by affine geometry. We provide theoretical frameworks supported by mathematical models to demonstrate how gravitational field strength influences wave propagation and energy dissipation. Keywords: Gravitational waves, affine geometry, metric perturbation, energy attenuation, spacetime deformation.
