You can play the sound files if you have the correct program for it, I use winamp and a plugin (iirc), but that's on Windows and you have a Mac. There is probably a program for it.

hit_wood1.ogg through hit_wood4.ogg are all fine, they are similar and sounds like a normal hit on a wooden door and should fit you perfectly. lurker_hit_wood1-4 are more of a heavy bang.
