摘要： PURPOSE: A multi-channel active noise control device for reducing the indoor noise of a high-speed railway is provided to offset noise by generating noise with a phase opposite to that of the indoor noise of a railway vehicle, thereby reducing the indoor noise. CONSTITUTION: A multi-channel active noise control device for reducing the indoor noise of a high-speed railway comprises a standard microphone(100), a control speaker(200), an error microphone(300), and an active noise controller(400). The standard microphone measures the indoor noise of a railway vehicle. The control speaker generates noise with a phase opposite to that of the indoor noise measured by the standard microphone. The error microphone measures a difference of the indoor noise and the noise with the opposite phase. The active noise controller offsets the indoor noise by using the noise with the opposite phase.
