Put a roof turbine on that hole it starts spinning but it is blocking the flow of air to the outside not speeding it up. The turbines are adjustable so that the spinning part is level even though the roof is slanted. If it did then it s as if you had some sort of a perpetual motion machine.

Climb up into your attic and look at the vents from the inside. Find the noisy turbine and apply the lubricant to the moving parts of the turbine. It was very annoying. Our turbine roof vents whirlybirds were really noisy and had some rattling that was causing some vibration in the house.
