Vibrations from motors, pumps, fans, and other moving components can travel through a structure. When the vibrations are transmitted to, for example, sheet metal, walls, or chassis, the surfaces can begin to oscillate and, in turn, emit sound. This is what is commonly referred to as structure-borne noise.
At Cabseal, we offer materials for vibration damping and structure-borne noise reduction, with solutions tailored to the specific design and the source of the vibrations. We work with products such as heavy-duty mats and materials made of bitumen, cork, SBR, and CR to reduce vibrations and limit their transmission.
Right from the startThe Difference Between Vibration Damping and Structure-Borne Noise Damping
Vibration damping involves reducing the movement or vibrations within a structure. Structure-borne sound damping focuses on limiting vibrations that have already been transmitted to solid materials and that might otherwise propagate and create audible sound in other parts of the structure.
This means that the material needs to be placed where it can actually affect vibration transmission. In some designs, it is the contact surface between two components that needs to be isolated, while thin sheet metal surfaces may need to be damped to reduce resonance and vibrations in the surface itself.
Heavy-duty mats and materials for various types of cushioning
Heavy-duty mats are used to add mass to a structure and can thus alter how a surface responds to vibrations and sound. For example, bitumen-based damping materials are used on sheet metal and other surfaces that would otherwise vibrate easily.
SBR and CR can instead be used where an elastic material is needed between components or contact surfaces. The material can help isolate vibrating parts from the surrounding structure, thereby limiting the transmission of vibrations.
The choice of materials therefore depends on whether the problem lies primarily in a vibrating surface or in the transmission between different parts.

The Right Materials for the Right NeedsDamping where vibrations occur
An effective solution begins with identifying where the vibrations originate and how they travel through the structure. We can customize damping materials to specific dimensions and geometries so that they can be placed on the surfaces or between the components where they are most effective.
If, on the other hand, the problem primarily involves sound reflected inside, for example, a machine enclosure, acoustic insulation can serve as a complementary measure.
