Analysis of Noise and Vibration in Subway Station Hall

Abstract

This study use noise and vibration analytical system to test and analyze the noise and vibration of subway station hall, draw the conclusion: analysis the noise test results when the vehicles through the subway station hall. The noise rises as the frequency increases, gets the peak value nearby 5000 Hz, the high of test point gives lesser influence to noise contribution. The vibration occurred in low frequency range, get the peak value in the frequency band from 70 to 80 Hz. Learn from the test position, the noise and vibration nearby escalator are higher than the other positions, that's because of the vibration and shock come into the escalator moving. The test results above offer the basis to for the subway station hall's vibration damping and noise reduction design.
