Grrr annoying sound

I am almost done with a major side quest. One chick commits suicide and a knife will be found next to her, the Wardens Projectile is perfect for the model. And i mean PERFECT. However, it makes an annoying sound. Like a "swish" sound over and over. Any way to stop it? I need the unit to be anywhere on the map, I stuck it in the middle of the woods but nearby units still heard it. Any suggestions/solutions?

Well, I see two possible scenarios here.

A) The sound is part of the model, in which case the model would need to be edited to exlude the sound. You could ask around the modeling forums to see if this is even possible and to find someone to edit it for ya.

or

B) The sound is remotely attached to the model in some reference. You could try exporting the model and then importing it back through the imports manager to get a disassociated version of it.
