Abstract：Research purposes: Subway has provided convenient communication conditions for people with its rapid convenience, comfort. But the noise of subway train and series of electromechanical device has been brought about extremely affection on people's life. Therefore it is need to study on the noise elimination of subway system.
Research method: Aiming at compose of subway ventilation and air-conditioning system and device, it analyses the main subway noise source and denoise noise elimination equipment choice in site measurement data.
Research results: Subway ventilation and air-conditioner is one of main noise source. Noise elimination denoise equipment responds to the request satisfying acoustics，aerodynamics，processing aspect
Research conclusions: The ventilation and air-conditioning system asks a subway to adopt rational denoise of science noise elimination measure. Dyadic impedance movie deadener can carry out effective controlling on noise and eliminates.
