When a train passes through the bridge structure, the low-frequency structural noise radiated by the bridge often is an important noise source disturbing nearby residents. The noise affects the quality of life and even causes harms to the physical and mental health of nearby residents. Therefore, more and more scholars begin to study how to effectively reduce the structural noise of the bridge. Currently, the treatment principle of brige noise mainly focuses on vibration isolation, vibration absorption, and optimization of the dynamic characteristics of bridges, very few researches have taken advantage of ascoutic short circuit principle to control the bridge noise. This article firstly analyzes the noise contribution volume of various parts of a bridge, controlling the bridge noise by utilizing the ascoutic short circuit principle based on the contribution of various plates of the bridge structure.
