Last year, large companies in rail goods traffic has done a related experiment analyzed the frequency characteristics of rail traffic noise. For product advantages and disadvantages of large sound barrier sound barrier a meter money, developed a complex product of two large impedance sound barrier sound barrier, in the main frequency range of rail traffic noise, acoustic performance product master sound barrier than excellent sound absorption coefficient for the analysis of oblique incident sound barrier barrier materials Shuo much money, there are advantages to prevent rain and dust violations. proposed a multi-channel impulse response method sound barrier installation method, which eliminates the reflection and scattering of the measured object impact point, suitable for measuring the uneven oblique incidence absorption coefficient of sound absorption interface, new experiments measuring the sound barrier demonstrate the effectiveness of this method. Let more efficient design and construction of large items. Master sound barrier height length product design specifications: product Shuo sound barrier height, length, should be based on the amount of noise attenuation barrier and the relative position of the sound source and the point of acceptance among road alignment, ground factors design. Sound barrier height should not exceed five. Om. When the sound barrier is longer than lkm, should set up an emergency evacuation mouth. Sound barrier material should have sound insulation, high-strength, low-glare, durable, fire-resistant, resistant to moisture and other properties. Sound barrier should be the strength of the structural design calculations and stability against overturning checking. Temporary road surface side of the sound barrier should reduce the reflection of sound waves, light waves, its form and color should be in harmony with the surrounding environment.
