Vibration damping material is used to eliminate structural noise and energy from a system. By damping the vibrations in a system, the material acts as a shock absorber – resisting the substrate as it flexes and returns to neutral when energy passes through its structure. That resistance sucks the energy out of the system as low level heat, instead of allowing it to the be transmitted. When the movements stop, the noise stops.

Types of vibration damping material
We have formulated two awesome solutions to stop vibrations. The first is our Damplifier line of sound deadening mat, which we offer in several standard sizes and thicknesses. The second is our liquid sound deadener, Spectrum.
- Damplifier Pro – This peel and stick, viscoelastic constraint layer damper is easy to apply. Just remove the paper backing and roll on with a hand roller to bond it to the substrate (typically metal or fiberglass). We also have a lightweight version (Damplifier) and a smaller Damplifier Pro CLD tile. It’s been over 20 years, and we have yet to test a material that performs as well as Damplifier Pro for NVH reduction.
- Spectrum – This liquid deadener can be used as a sound deadening spray or brushed on with a roller. Apply it in 1mm layers to the recommended thickness of 2-3mm. At 3mm, it will actually perform as well as Damplifier Pro – although you can go up to 5mm of total thickness. If you’d rather apply with your gloved hand or a trowel, the Spectrum Sludge version comes with an activator that increases viscosity from like chocolate syrup to more like peanut butter.
We also have a variety of other soundproofing materials that are effective for structural noise, mostly used for sound isolation. OverKill Pro is a rubber infused closed cell foam, and then we also have several pure rubber products (like UnderBlock rubber flooring underlayment). Contact us for more details!
