A system for reducing noise of a sun roof for a vehicle is provided to prevent an eddy flow from occurring at a roof panel by generating a proper synthetic jet according to a control operation of a controller based on opening/closing states of a sun roof and a vehicle speed. A system for reducing noise of a sun roof for a vehicle comprises a synthetic jet generator(100) and a controller(200). The synthetic jet generator includes a cavity(110) and a vibration plate(120). The cavity is provided inside a roof panel(300) formed at a front side of a sun roof(400) and is formed at an upper side thereof with a micro-hole(111). The vibration plate is provided in the cavity to respond to supplied power. The controller controls power applied to the vibration plate of the synthetic jet generator. The vibration plate includes a piezoelectric device.
