Is your issue vibration-induced, general fan noise, or is it the actual air that's moving through the system?

I am moving my grow room from one side of the house to the other just to make it more discreet because of the fan noise. I assume most of the noise comes from all that air moving through the system. Someone who doesn't know what a grow room fan sounds like it won't be a problem but for someone like a cop he or she would know what one sounds like

Air flow noise can be reduced if you use smooth steel pipe rather than corrugated.
You could try a fan speed controller. Sometimes when those fans are wide open they tend to hum a bit, dial it back a little and it'll quiet down.
