Abstract: PURPOSE: A device for reducing the high frequency noise of a vehicle is provided to improve an effect for reducing vibration generated in an engine and a transmission assembly, to reduce noise in high frequency band area generated in a transmission, and to reduce the total weight of the vehicle and improve fuel consumption rate by mounting a battery for supplying electric power and reducing vibration and noise of high frequency band areas to a transmission mounting bracket connecting the transmission to the vehicle body. CONSTITUTION: A device for reducing the high frequency noise of a vehicle is composed of a battery case(21) and a battery(22). The battery case of a predetermined size is bolting-combined and mounted to a transmission mounting bracket(2) embedding a bush(2a) therein. An end of the transmission mounting bracket is bolting-combined to a transmission(T) and other side to a vehicle body(5). The battery is detachably installed in the battery case to function as a mass damper.
