Here's a little something I did on my Tizona G2N:
I've always been annoyed by the hollow echoing sound if you knock on the underside of keyboard. It's there since there's empty space between the PCB and the plastic parts that sticks out from the bottom frame to support the PCB.
So I opened the thing up and cut out some pads out of felt to put in there.Show Image(http://puu.sh/mZf1w/c8dbcc344b.jpg)
The felt pads are slightly thicker than the height of the plastic lines there to support the PCB, however it's also soft so it gets pushed down by the PCB and nicely fills up any gaps.
The sound made becomes dull after reassembly, kind of like the difference when you replace cheap thin ABS keycaps with thick PBT ones. It did also seem to somewhat silence the sound of typing it self. I'm pretty satisfied with the results I'd have to say.
I do this to all of my keyboards.
I use felt, waffled rubber drawer liner, and the thick EPDM that I make my mats from, sometimes all 3.
The waffle rubber is the most compressible, and does not slip around as much as felt. The EPDM is heavy and I try to lay it at the bottom so that it just muffles the vibrations by brute force and weight. For voids that are not simply large and flat and accommodated with sheets, I fold layers into rectangles or cut strips and roll them into cylinders to get just the right sizes and shapes.
Other people have used multiple layers of duct tape alone, or duct tape along with other materials.
I use PE-Foam. I got it from a huge package in which my monitors were. So I didn't buy it. You could probably order it online from a shop that is selling packaging materials.
I also have waffled rubber drawer line. I got it from a local store.
Technically, any sound dampening material works, just use the one you can get your hands on.

Sorbothane dampening pads are about as dense as you can get. Pricier but works great.

As do I. Makes it sound much less hollow and gets rid of some of the plasticky sounds.
I use either drawer liner from the dollar store. Drawer liner lets you fill the space just right and get the right amount of compression. You don't want it too tight or it actually can sound kind of odd.
As nice as it is to sound deaden the inside of the case, putting the keyboard on something soft helps much more. You can cut out a piece and secure it to the bottom of the outside of the case if you don't want to type on a soft surface.
Yoga mat works really well for this but it usually isn't too cheap, especially if it's just for one keyboard.
And there are also my mats .....I use this daily at work

And there are also my mats .....Those look really good, do you think they would help slightly reduce the noise and ping on a Ducky 1008XM?

I have enough stock for a few in the small sizes for HHKB, Poker, etc, (approx 4.3"x11.5" or 110mm x 290mm) and I hope to get some larger pieces for standard-size boards in the next week.

Any flexible material separating hard layers will reduce resonances and chattering as it keeps the flat surfaces from becoming sounding boards.
The easy test is to fold a towel and put it under the keyboard. A firm rubber mat will do less than the towel, sound-wise, but it is also helpful for traction and keeping the keyboard from moving.

You just stack layer on layer inside the case or what?

Where do you get those?
Is that some stuffed between the pcb board and the keyswitch plate as well?
I was experimenting with that to see if I could reduce some of the notorious ping of the KUL ES-87 with MX Clears. It pretty much went away when I changed the switches out to Zealio 62g/65g.

Pretty much. The inside case isn't usually flat so you need to make it work. Usually I'll start with one full size layer and then make each one shorter (on the front side).
Here's an example of my KUL ES-87 with a single layer inside. Notice that I had to cut out around the stems that support the PCB and the cable. After that, I added more layers but not so much towards the front.Show Image(http://s7.postimg.org/dwhi8tvtn/IMG_3045.jpg)Show Image(http://s7.postimg.org/t3xht6nob/IMG_3046.jpg)Show Image(http://s7.postimg.org/gf379ihjv/IMG_3047.jpg)
I stuffed my Focus FK-2001 with paper towels. The FK-2001 is pretty flimsy but the added weight makes it feel better built than it actually is ;)

The ones form the 80s aren't super bad. The 90s ones are super creaky! The earlier ones are a bit heavier. The cord is obviously bigger too.

However, mine is unique because despite it being a later made board in China, it still uses complicated switches.
