When sound waves encounter sound barrier sound barrier installed in the communication process, it will happen reflection, transmission and diffraction three phenomena. Barrier can prevent the spread of the direct sound, and there is sufficient transmission acoustic attenuation, while transmitting acoustic influence is negligible. So the sound barrier, sound effects sound barrier in general can be said that the bridge sound barrier noise reduction amount, which reflects the sound through the sound barrier to shield the two skills. Between the sound source and the receiving point to insert a sound barrier, set up a barrier of infinite length, acoustic diffraction past only from the top of the barrier, and in the subsequent formation of an acoustic shadow zone Anping sound barrier, as the light is blocked the formation of a shadow object that. In this acoustic shadow area, people can feel the noise significantly reduced, and this is the sound barrier noise reduction. Sound barrier structure: Outdoor sound barrier generally use brick or concrete structures, interior sound barrier cited steel, wood, PMMA / POLYCARBONATE SHEET pull plastic, gypsum board and foam aluminum structure.
