Characteristics of Interior Noise In The Monorail And Noise Control

摘要

Because of the exclusive driving mode and configuration, the characteristics of interior noise inside the monorail cabin differs from the traditional railway system'1'. Therefore, the realtime noise emission under various speed was captured so as to define the upper limit of sound pressure level and rank the principal sources by performing spectral analysis. After that, relevant sound packages were designed to taking control of the interior noise. The experimental verification demonstrates the treatment meet the requirement of noise reduction..
