Extract the ZIP file into your base Amnesia installation folder. If you installed it using Steam then this should be in your Steam folder (e.g. C:\Program Files\Steam\), at the following location:

[steam folder]\steamapps\common\amnesia the dark descent\

Once the files have extracted, then simply run the game. You should hear the new sounds if and when you start to go insane. Note that they're quieter than before, but they are there.

If the sounds are not replaced, they might have extracted into the wrong place. In that case browse through the ZIP file until you find the actual sound files, and extract them to:

[steam folder, etc]\amnesia the dark descent\sound\ui\

If you want to change the files yourself, the original ones can be found in the above folder. All of the teeth-grinding sounds start with 'sanity_drain_". I used Audicity to change them.
