摘要

Active noise control (ANC) technology is a powerful complement for the traditional noise reduction technology. Analysed the current situation of noise control for rail vehicles; according to the application range of ANC technology, analysed the application strategy of ANC technology for rail transit vehicles; measured and analysed noise characteristics of an electric locomotive cab under different operating speeds and railway conditions, and proposed the ANC system scheme based on the whole cab space. Through the preliminary simulation calculation, the total sound pressure level in cab can be reduced by 4 dB(A). It provides a new idea for the noise control and comfort design of rail transit vehicles.
