A CLD is a material that adheres to panel to reduce resonant noise by using a viscoelastic polymer, in this case butyl rubber, sandwiched between two constraining walls to strengthen or "deaden" the outer wall. The outer aluminum backing reinforces the panel and reduces vibrations and rattles. It deadens the panel it is attached to, thus the name sound deadener.
