Damping Techniques for Noise and Vibration Control
23/03/2016· Damping is one of the most effective methods of controlling noise and vibration. It is a process that converts vibrational energy into heat, eliminating the vibrational energy through friction and other processes. Increasing damping or stiffness can both reduce resonant vibration and the resulting noise by preventing the vibration from travelling through the structure.

sound. Damping, however, suppresses only resonant motion. Forced, nonreso-nant vibration is rarely attenuated by damping, although application of damping materials sometimes has that effect because it increases the stiffness and mass of a system. A damping treatment consists of any material (or combination of materials) applied to a component to increase its ability to dissipate mechanical

Simple Effective Way to Dampen Irritating Vibrations
28/03/2018· I put them under my bed legs to dampen the vibration traveling UP the leg through the floor and waking me every night. Sally Schneider. Having tried various ways of using them, including stacked on hockey pucks, I found that simply placing one each on top of a small piece of wood, and then under each of the bed legs works best. (A reader wrote to say she found that placing them on TWO

Sound and Vibration Control Strategies DEICON
Sound & Vibration Damping back to list ↑ The common approach to mitigate sound and vibration caused by acoustical/structural resonance, is adding damping to the acoustic plant and structure. Damping dissipates some of the sound/vibration energy by transforming it to heat. Passive, semi-active, and active control methods can be used for Sound & vibration damping. The traditional
Acoustic quieting Wikipedia
Acoustic quieting is the process of making machinery quieter by damping vibrations to prevent them from reaching the observer. Machinery vibrates, causing sound waves in air, hydroacoustic waves in water, and mechanical stresses in solid matter. Quieting is achieved by absorbing the vibrational energy or minimizing the source of the vibration.
