We offer sheets and
custom solutions |
| (Noiseless Metal) is a
range of products for damping structure borne sound,
consisting of two metal facing sheets bonded by a
viscoelastic core. The sound damping qualities of
the viscoelastic core are temperature dependant. For
this reason the panels are supplied with cores
optimized for different temperature ranges,
depending on the applications in which they are to
be used.The two metal facing sheets in the panels
are usually cold rolled steel, (Often referred to as
Noiseless Steel) but in principle any type of metal
or alloy can be used, as can surface-treated sheet
of various kinds. The metal facing sheets are
ideally equal thickness, but a certain amount of
asymmetry can be tolerated with minimal loss of
acoustic properties. |
| Noiseless Metals serve a dual
purpose. It damps the resonant modes of the
structure borne sound and it replaces the sheet
material that would otherwise be used in the
construction of the component, without any increase
in thickness or weight. The acoustical deadness of
the panels is often sufficient to
replace the need for additional heavily loaded
polymer layers needed to screen the noise radiation

Key Benefits
- Replaces structural material and is
therefore virtually zero weight added
- Damping is designed into product
- Increase in sound transmission loss often
equal to addition of equal mass of barrier
material to mass of metal panel
