地铁车内噪声影响因素分析与改善
Analysis and Improvement of the Factors Influencing Interior Noise of the Metro
摘要
Abstract
The main noise source of the Metro is the wheel-rail noise. This noise will generate a reverberation sound field in the tunnel after reflecting from the tunnel's wall and then penetrating the carriage's structure into the carriage, which will affect the riding comfort. In this paper, the qualitative statements of the influence factors of the wheel-rail noise in classical theories and the relevant standards are studied. The test data acquired in the domestic Metro lines is used to quantitatively analyze the influence of each factor on the noise inside the carriage. On this basis, suggestions for comprehensive control of the noise inside the Metro are put forward. This work may provide a reference for the subway route planning.关键词
