ArmaSound RD
The high performance sound absorption for a quieter environment
ArmaSound is a versatile acoustic absorber designed for use in a variety of different acoustic applications. A high performance sound absorber which also offers additional barrier (transmission loss) performance and both vibration damping and de-coupling (isolation) properties.
Delivering optimal performance at lower thicknesses than traditional materials, ArmaSound RD is a uniquely advanced 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.
ArmaSound RD provides a dust and fibre free solution that is suitable for use in a range of demanding environments.

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

| ArmaSound RD and ArmaChek R |
|
|
| ArmaChek R provides an excellent barrier layer for all types of insulation coverings. When used in conjunction with ArmaSound RD, very high levels of noise reduction can be achieved in pipeline systems for marine and offshore, wastewater pipes and acoustic jackets. » more about ArmaSound Industrial Systems |
