Compressors should be innately decoupled well from the floor so that the vibrations do not spread through the floor (structure-borne sound). The manufacturer usually pays attention to this during the installation. If not, you can use our foam rubber to decouple the device or a compressor from the floor. The airborne sound emitted from the compressors or loud devices in general must then be absorbed.
For an attenuation of the noise, you must enclose the compressor, thus build a type of room around the compressor and line this with a foam at least 5 cm thick - if the area is dry, our rebond foams are most suitable - we recommend our rebond foam in particular at this point because it is heavy and thus noise can be absorbed even better. The thicker, the better the insulation. To maximise the insulation, you can also build a triple construct - first, a rebond foam sheet is adhered, then our double-sided adhesive bituminous foil and on that our rebond foam.
You will find more detailed information on how this construction works in the Help topic area under “Noise insulation”.
If the compressor is outdoors or in an area which is damp or wet, then foams are unsuitable because they absorb water and disintegrate. You should also enclose compressors outdoors and then proceed as described above. The thicker you choose the foam, the better the insulation is in turn.
However, most compressors have to be ventilated also. Naturally, this cannot be combined directly with noise insulation. Thus you have to build a type of ventilation duct too and line this also with foams so that air can be extracted or discharged. Ideally, you should interlace the duct so that the sound cannot be emitted directly. It is best to use the rebond foam again here also.

Fire protection is an important issue when installing acoustic foam sheets.
The quality of the acoustic foam is largely responsible for its absorption behaviour.
Noise insulation is much more complicated than pure acoustic improvement or resonance removal.
You can easily mount foam because it is very light compared to other materials
