Noise sources identification based on microphone array theory was firstly introduced, A method was derived, which can be used to analyze effect of noise emission from railway viaduct to noise reduction of noise barriers. Vibration and noise emission of railway viaduct and noise barrier were studied using field testing with microphone array technology and vibration testing. The results concluded that noise emission from the viaduct has remarkable effects on noise reduction of noise barriers compared with the effects of noise emission from the noise barriers themselves, which is neglectable.
