How to install system sounds?

[MintHat]

I'm not sure if this should be here, or in the newbie questions, so my apologies if it's in the wrong one.

So, I'm trying to install system sounds, but I haven't got a clue how to do it.
This is the one I want to install:

Is there a "how to" somewhere I can read? (It was stated in the above link, that one should read the manual).

Thanks (again) for helping.....

Edit: I forgot to mention, I'm using Mint 8 main 64bit

There is a lot of useful information here that might help.
