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
