I just got a used VN1600 Mean Streak with unwanted add-ons. I just removed everything and all was o.k.
Since I'm a newbee I don't know much about the standard configuration of your bike.
If the add-ons are not standard, try to remove them, just to check where the problem comes from.
What I learned from windshields is, that they are very good to reflect noise from other locations.
