How to keep it quiet

[rceebuilder]

I used to cut my kits with saw and other conventional tools. But after having my own CNC router I put all of my old tools to shelf . But now I have another problem : noise . I'm living in an apartment and I have no other chance but to run the router in the evenings . I don't want to disturb my neighbors. My router creates noise in both case when it cuts air and cuts wood. I tried to wrap it with foam cloth but the noise is still above my limits. Does anyone have an experience like this??

My first suggestion would be to get a closed air space all around your set up.
Start with a layer(2"?) of foam or bubble packing underneath, between the m/c and the bench.
Then build upwards from that. The key to reducing noise it to prevent any air passage between the source and the outside world, and any rigid path that will conduct it. Rigid material acts just like the sound board of a musical instrument. Still air is a good insulator, but any gap will be a good transmission path.
