WebMar 19, 2024 · High sound pressure causes the CLD to flex, which creates shear strain between the layers and plastic deformation of the damping compound which is converted to heat energy. Low sound pressure (when the wave is 180 degrees out of phase) causes flex in the opposite direction, and more shear strain, deformation, and conversion to heat.
