Acoustic foam damps out airborne noise

SDS AcousticFoam is a new range of high-density sound-absorbent self-adhesive open- or closed-cell acoustic foam dampers.
Sound Dead Steel has launched a range of high-density sound-absorbent self-adhesive open- or closed-cell acoustic foam dampers - SDS AcousticFoam.
Sound Dead Steel deals with transmitted noise, but does not have a great effect on airborne noise, and that's where the SDS AcousticFoam comes in.
For example, if the noise from a pump or compressor needs subduing, an acoustic guard or enclosure could be manufactured from steel.
Bonding SDS self adhesive dampers on the steel panels would dramatically reduce the radiated noise from these panels, but the airborne noise would still be bouncing around inside looking for gaps to escape.
Covering the inside surface with SDS AcousticFoam (flat or eggbox profile) will absorb a significant amount of airborne noise.
Sound Dead Steel can provide a manufacturing service if required.
The foam can be fixed to almost any surface and if bonded to a wall would reduce the reflection of sound from that surface.
It can be placed inside a wall mounted enclosure with perforated steel on the front to protect it, this is useful when rockwool derivatives are not suitable due to hygiene etc.
The material is fire certified and relatively inexpensive.
