Topic tags/keywords: acoustics sound soundproof noise foam undercoating

Hey Guys. Being that I usually work from my garage I am often worried about noise and its effect on neighborhood moral…

While talking with an acoustic specialist at work with regard to knocking down some of the noise as it is leaving my tools we discussed things like different foams, mass damping, etc. His ultimate suggestion for tools like router tables, band saws, and table saws was to use that Rubberized Undercoating stuff and basically cake it all over the inside of the tool housing similar to how you would do it to the inside of you cars fender. Anyway, you can buy it for around $6 a spray can at Wal-Mart if anyone is interested in trying it out.

Most of the noise is from either a Universal Motor (screamers) or the cutting action. Could help the motor noise a lot. So good for portable planers and routers.

One idea that was given to me is to put some double faced tape on the back of some ceiling tiles (12×12) and stick them to the enclosure surrounding the router. I plan to try it when I build my router table because its so cheap and easy to “undo”.

Take this with a grain of salt because I’m certainly not an engineer. We have a few office buildings where sound has been a problem and we had a consultant come in and give us some advice. He said you can only do three things with sound waves: block them, absorb them, or mask them.

He suggested we try, in that order, to block them, then absorb what can’t be blocked, then mask what can’t be absorbed.

I would think you could enclose as many of your tools as possible to block the sound waves, then put a material to absorb the sound (foam, egg crate insulation, ceiling tiles, etc), then hope that it’s raining or a semi is going by to mask it.
