Noises are hard to diagnose in words.
What bandsaw do you have?
What upgrades if any (carter guides, cool blocks etc.)
video would be helpful, but have a look at the thrust bearings (bearings in back of the blade, if they are frozen and the blade is wearing a groove in the upper or the lower, that could be the problem.
Also, if you have steel guide blocks or the throat plate is too close to the blade, that could be a problem.
I am going to guess the thrust bearing or guide blocks since it is when you are cutting wood... meaning you are putting pressure on the blade and possibly pushing it into one of these guide elements...
Hope that helps, at least something to look for..
