One important request before you start to embed these sounds in your map:
Always be sure you are using THIS path as sound directory:
..\QUAKE2\CHAOS\SOUND\WORLD
...if you won't use it, the hearing pleasure for the player later in CHAOS won't even start! =

And write me, if you don't find the desired sound and wan't something completely new!
