Supply Hao Feng venetian blinds bore hole acoustic sound barrier wall can be customized

Louver hole sound barrier has water, heat, UV, from climate and weather; device type construction, improve work efficiency, shorten construction time, reduce project costs and so on. Louver hole sound barrier Specifications: General 1960 * 500 * 100,2460 * 500 * 100 size can be customized according to customer requirements; Material: galvanized steel, aluminum louver hole sound barrier widely used in highway, urban elevated, residential areas and other excessive noise The area can be used, reducing overhead when the acoustic wave propagation process, meet the sound barrier, reflection occurs, transmission and diffraction three phenomena. Usually we think that the barrier be able to stop the spread of the direct sound, and sound have sufficient attenuation transmission while transmitting sound effects can be ignored. Therefore, sound effects sound barrier noise amount may generally be said that it reflects the sound barrier above two acoustically transparent shield skills. Between the sound source and the receiving point insert a sound barrier, set up barriers infinite sonic barrier above only diffracted from the past, and in the subsequent formation of an acoustic shadow zone, as the light is blocked by the formation of a shadow as the object. In this acoustic shadow area, people can feel the noise significantly reduced, and this is the sound barrier noise reduction effect. Load bearing bridges reduce structural cost
