No, it wouldn't. The ping is audible because there's a cavity under the PCB filled with air where sound waves can travel and reverberate. By filling the cavity with something porous that inhibits free sound wave propagation dampens resonant noise within the keyboard. You can put something under your keyboard too which will help further, but not as much as putting something under the PCB. A mat on your desk would mostly just help with punching your keycaps reverberating through your desk.
Isn't that just the noise from the keys popping back up? A ping is a ringing noise caused by vibration of the springs and sounds completely different from the second click in the audio clip.
Yes it definitely changes HUGELY depending on the keycap material. Also, you could install o-rings if you want to get rid of the ping.
Thanks for all the information.
Can the ping noise also be affected by the keycaps at all? The stock keys are really thin, would something like a set of PBT thick keycaps help dampen the sound?
Actually can't really hear it, but if you're talking about a sound of recoil/metallic resonance (known as "ping" here), it's very easy to fix. Place some dampening material under the PCB. A popular choice is some cheap rubber-foam drawer liner, like this:Show Image(http://www.rabbitlaserusa.com/images/Supplies/NonSlipDrawerLiner2.jpg)
It comes in many colors and also thin varieties that you could add a double layer of (single layer for the one shown above). Cut to size of the bottom tray, cut some areas out that will go around plastic protrusions where the USB cord channel is, etc. Place into the bottom tray, reassemble the keyboard. Yes, it will void your warranty, but it will make your keyboard overall noticeably quieter--this goes for all other brands of keyboards of this design.

This leaves an ugly mark on the bottom of the keyboard after some time
