    Characteristics of Sound Insulation and Insertion Loss of Different Deloading Sound Barriers for High-Speed Railways

    When a high-speed train quickly passes along the sound barriers installed on the two sides of a viaduct, the fluctuating wind pressure acting on the sound barriers causes an increase in the aerodynamic loading...

    Study on the Sound Radiation Directivity of a Railway Wheel and the Relationship between Directivity and Mode Shape

    Due to the complex geometry of a railway wheel, the shape of its modes may have to be properly considered to understand and predict the sound radiation directivity around it. A straight-web metro wheel is stud...
