Sound damping is the restraint of vibratory motion which dissipates energy transfer. To illustrate the mechanics of damping, consider a simple swing set. Unless a child seated in his swing keeps pumping and pushing, the back-and-forth motion of the swing will slowly come to a stop. This is a result of the air's friction opposing the motion and removing energy from the system. This process of destroying energy is called damping.
Viscous damping is achieved by layering liquid lubrication between two moving parts such as two sheets of drywall. This destroys energy transfer, much like our swing set example, by impairing the surface's ability to conduct vibration. As a result, structure borne sound waves collapse. The products listed here target the reduction of sound transmission through this sound damping process.
