Note that stapling is not a particularly enjoyable way to put the tiles up You get rained on by ceiling tile dust which hurts to breathe (and is probably full of silicates or other bad stuff). I stapled the first 5 of my ceiling and then used 1 1/4 screws for the rest.
I have noticed in the band room and orchestra room they have acoustic tile so on the ceiling and on some of the wall. The wall is glued? on and stops 6" short of the ceiling it comes down several feet but stops well short of the floor. Big patches of wall with no tiles. So they feel any little bit extra helps but no need for total coverage to get some benefit.
Bil lD.
Totally agree, although I stapled the whole thing. Eye and breathing protection mandatory and I also wore a hat.
You can actually make a room "too dead" relative to sound for most applications. So yes, some "moderation" is a best practice.

Hey Jim, Just curious, in your shop photo: what are those two yellow things with the black elephant trunks in the right hand foreground?
--I had my patience tested. I'm negative--
Grip Tight featherboards that I use primarily on the bandsaw. They are the yellow plastic versions. There's a thread in the classifieds (shop cleanout #2) that shows a couple of the original wood ones the manufacturer started with, although I doubt that thread will be there much longer) These have a magnetic base and you position them on the table so that the features and/or rollers contact the material and hold it against the fence.

Your router spins at a very high speed and creates some very high frequencies you can dampen the noise a bit by putting rubtex (it's a dense neoprene like material that is used for insulation)
Since sound and vibration are linked applying a dense foam to the inside of the router table will dampen the noise a bit. You don't have to seal it up you just want to bounce the sound around in the dense foam.
Think of it as playing a pin ball machine only with noise.
