I see , but what you are looking for , is an increased awareness of the AI depending the level of difficulty , however with the current NPC AI , it's not possible , probably hardcoded .
Maybe when the CK will be out , some modders will try to enhance the AI detection and behaviour depending the level of difficulty , like a larger cone of detection in expert/master difficulty and better reactivity to sounds etc ...
But i suspect it is hardcoded and won't be possible to change that , so in the mean time , the only thing you can do is nerf yourself with self imposed "house" rules , as other posters said , when you "feel " you are detected , you get out of sneak by yourself ...
It's difficult to give another advice ..
