Application of vibration damping materials to structures and panels dissipates the vibrational energy into heat. The primary effects of damping treatments are:

• Reduction of vibration amplitude at resonance.
• A more rapid decay of free vibrations. This avoids the accumulation of energy due to a series of impacts.
• Attenuation of structure-borne waves propagating along and through structures.

Examples of resonant vibration involving repeated impacts:

• Materials falling into and onto holding vessels or hoppers
• Chutes and ductwork that are pneumatically conveying particles such as rock, stone or wood-chip.

The range of “Soundguard” products such as Soundpaint – Silentstep – Sylomer are products that provide efficient reductions of the sound source. They are provided as:

• sprayable compounds
• flexible sheets
• heavy duty tiles
