PURPOSE: A device for damping noise of a manual transmission is provided to prevent transferring vibration and noise from the transmission to a transmission lever, and improve inner silence. CONSTITUTION: A damping device includes a vibration sensor(12) installed in one side of a cable connected to a transmission(4) and detecting frequency of vibration transferred from the transmission to the cable; an actuator(16) installed in one side of a transmission lever(2) and occurring vibration having constant phase, an ECU(Electric Control Unit) detecting the phase according to the signal from the vibration sensor and driving an actuator to occur the phase signal of opposite phase. The vibration transferred from the transmission to the cable(6,8) is detected in the vibration sensor and frequency band of vibration is sent to the ECU if vibration and noise is occurred. The ECU detects the phase and finds out the final phase as judging transformation of the phase when the frequency phase, detected in the transmission according the length of the cable from the transmission to the transmission lever, is transferred to the side of the transmission lever. The ECU transfers the phase signal to the actuator. The actuator occurs the vibration having the phase of the opposite phase in the cable and the noise is reduce.
