recommend video content fix?

[juggernaut]

I have purchased 1 video a few weeks back and have been so busy have not really got to watch the whole 10 mins of it. I am going to be editing it today an have noticed alot of backround noise. IE camera shuffle's, things dropping on the ground and heck there is even a part where someone coughs and another where someone sneezes. Would it be cool to place a sound file over this? Like some music, I can prob go DL some adult moaning sounds but whenever I have seen videos like that I hated them cause its so easy to tell the sound bytes are fake. Any help would be great. Thanks Jugg..
