HIGH PERFORMANCE ACOUSTIC INSULATINGMATERIAL FOR A QUIETER ENVIRONMENT
ARmASounD RD – Sound absorption with low thicknesses
Your benefit:ArmaSound RD is a versatile acoustic absorber designed for use in a variety of different acoustic applications.
A high performance sound absorber which offers additional barrier (transmission loss) performance and both
vibration damping and de-coupling (isolation) properties.
Delivering optimal performance at lower thickness than traditional materials, ArmaSound RD is a uniquely advan-
ced open cell acoustic insulation material. With a peak absorption frequency determined by the insulation thickness
and the material density ArmaSound RD can be engineered to target specific problem frequencies.
A brand-new material class for acoustic protection

high density and high flow resistance
Sound Absorption4 Open cell structure with complex pore geometry allows
for effective absorption of air-borne sound across a broad frequency range.
4 Unique combination of physical properties allows absorp-tion to be maximised at key “nuissance“ frequencies.
Sound Barrier (Transmission Loss)4 Relatively high density and high flow resistance offers an
effective barrier to sound.4 May be suitable for use as an alternative to complex “foam
barrier“ multi-layers.
Vibration Damping and DeCoupling (Isolation)4 Visco-elastic properties help dampen or deaden reso-
nance effects in metal pannelwork (e.g. enclosures or ducting) which helps to reduce associated “re-radiation“ effects.
4 Reduces structure-borne noise transmission when used as isolation pads.

Acoustic benefits
Product range
The world is becoming noisier and noisier - life is becoming more and more hectic. Many noise sources cannot simply be switched off and this creates additional stress in our everyday lives. Noise is now one of the greatest environmental problems of our times. Noise protection is therefore becoming increasingly important in the workplace, in public buildings and, not least in residential buildings. Besides the preventionen of sanitary problems noise protection provides a better quality of life free from the stress
that noise causes.
