Vibration damping is a term used in ergonomic, industrial, and electronic applications where there is a need to lower the amount of energy a system produces. Once vibration has been damped, energy is transferred to appropriate channels and a reduction in noise propagation occurs.
There are myriad reasons why vibration may be undesirable. It may manifest as a simple annoyance or present a potentially catastrophic environmental factor.
Types of Damping Materials
At Technicon Acoustics, we rely on several different damping materials to ensure our products stop vibration before it becomes a problem. Determining which material is suitable for vibration damping is determined by the specifics of their intended application. Some of the most common vibration damping materials include:
Rubber is an ideal material for vibration damping applications. It absorbs energy before re-releasing it into the environment as heat, which helps quickly isolate vibration. While it doesn’t have true damping abilities on its own, it can be a powerful tool when paired with other materials. While rubber has minimal vibration damping effects, it does absorb energy and release it as heat, which makes it an ideal material for isolating vibration energy.
Polyurethane is a newer material option in the vibration damping space. More modern substances like foam and foam-like polyurethane products can absorb a system’s excess energy. Polyurethane products’ cell structures and densities can even be custom-engineered to fit specific applications.
Polyvinyl chloride (PVC)
Polyvinyl chloride sheets offer superior chemical resistance and serve to quickly absorb vibrations. These products are typically utilized as sound barriers, but may also be used to damp vibrations on enclosure surfaces.

Frequently Asked Questions
What is the difference between DM and Mass Loaded Vinyl?
- DM is a vibration damping material used to change the resonate frequency of the vibrating surface. Mass Loaded Vinyl is a sound barrier material used to block noise transmission.
How does Damping Material Work?
- Damping materials are designed to damp vibration in structures. Most are viscoelastic materials that use mass to change the resonant frequency of a substrate. They dissipate the mechanical energy by converting it to heat. By limiting transmitted vibration through enclosures and structures, many noise problems can be eliminated before they enter the environment.
What are the two types of Damping Materials?
- Extensional and Constrained. An extensional strain of structural substrate deforms damping material causing energy dissipation. A constrained layer has a high modulus material top layer, viscoelastic middle and shear strain created in the viscoelastic layer.
Where are Damping Materials commonly used?
- Platforms, partitions, hulls, decks, walls and other structural components are prime applications; however, we can provide a custom solution for you and your particular problem.
