Plate inserting type metal sound barrier with partitioned sound bridge
The invention discloses a plate inserting type metal sound barrier with a partitioned sound bridge. A conventional manner for partitioning a sound bridge in the sound barrier in a plate inserting type structure is improved, opening rubber materials with different sound-wave propagating resistance are used as interlayer pads; besides, perforated structures of different bore diameters are used for connecting parts, so that an abrupt interface on a sound-wave propagating road is generated, and the transmission of sound energy is continuously blocked; therefore, the purpose of sound elimination is reached. The sound ray diffraction lines at the top of the sound barrier adopt an oblique plane, so that structures of flow guiding plates are additionally arranged; therefore, the noise and air flow along with the noise can be slowly released.
