Specifications 

SOUNDOWN Vibration Damping Tiles are an easily

applied damping layer for stopping reverberant “ringing”

vibration in heavy plate constructions. Structural damping

material consumes vibrational energy and transforms it

into heat. It dissipates vibrational energy in the structure

before it can build up and radiate as sound. Substrates

upon which the tiles are commonly installed include:

steel, aluminum, and fiberglass laminate. Vibration damping

loss factor (n), at 1,000 Hz for the 3/8" tile, exceeds 0.10

on aluminum plate up to 0.40". Even greater damping

values are obtained when the material is installed as a

"constrained layer" treatment as shown on the bottom

diagram to the left.

Damping tiles and sheets are a polymeric product manufactured in accordance with MIL PRF 23653D.

Soundown’s standard tile and sheet products are Class 2

which are optimized for a temperature range of 55oF to

90oF. For temperature of 35oF to 55oF Class 1 tile are

available in 3/8” and 5/8”. These products are resistant to

fuel, water, and fire. All product configurations pass UL-94V

and ASTM D-635 flame testing.

These damping materials are bonded to the treated structure using 100 percent solid epoxy systems such as the

TA-30 resin supplied by Soundown Corp. Our 1/16", 1/8"

and 1/4” damping material can also be supplied with

pressure sensitive adhesive (PSA) for use on thinner
