How Insulation Damping Works

Use: to reduce noise radiated from vibrating surfaces

Physical Properties: Viscoelastic. Damping coatings take many forms. These are mastics for spraying, troweling, etc., and there are tapes and sheets with pressure sensitive adhesive.

Damping treatments are sometimes combined with absorbers.

Effectiveness is expressed as a "loss factor" which is the damping/stiffness ratio of a material.
