A noise reduction device for a negative pressure line of a brake booster is provided. The improved noise reduction device is disposed in a vacuum hose, and includes a negative pressure line of a vehicle in which a brake booster and a surge tank of an engine are connected via the vacuum hose to use negative pressure of the surge tank. In particular, noise caused by pulsation of an air flow and vibration of a valve which occur due to an operation of an engine piston is reduced.
