Original Abstract Submitted

A method for improving vehicle noise, which improves noise generated from a centrifugal pendulum absorber (CPA) after a vehicle turns off includes collecting real-time driving information according to an operation of the vehicle through a driving information detector, determining whether the idle condition is satisfied based on the real-time driving information; determining whether a transmission P stage is engaged and whether a brake operates when the idle condition is satisfied, and reducing rotation of a CPA mounted turbine applied to a torque converter through at least one of transmission clutch and brake operations at a time when an engine turning-off signal is input in a state of satisfying the transmission P stage engagement or brake operation condition.
