What are good vibration control materials (granite, marble, steel, wood, glass, etc.)?
The choice of materials for effective vibration control is critical. It is important to remember that energy (e.g.: vibration) is never destroyed, it can only change form. A component is subjected to a number of sources of vibration and resonance: A) energy travels from the speaker and air conditioning or heating systems through the floor and up through the equipment rack into the bottom of the component, B) air-borne energy travels directly from the speaker towards the component’s chassis, C) vibration and resonance are created internally by motors, spinning fans and buzzing transformers. A correctly designed vibration control product will deal effectively with all of these sources of unwanted vibration and resonance. Placing a component on a hard, rigid surface will readily allow vibration to easily transfer into the component’s chassis. Even though granite or marble are heavy and massive, they ring significantly when their surface is excited and they do not not have any ability to a
