Abstract
The utility model relates to a sound barrier unit plate device preventing noise pollution and belongs to the field of environment protection. The sound barrier unit plate device preventing the noise pollution comprises an acoustic board, sound absorption material and a sound barrier, wherein the sound absorption material is arranged in a cavity formed between the acoustic board and the sound barrier. The sound barrier unit plate device preventing the noise pollution enables sound waves to enter the porous fiber sound absorption material through sound absorption holes in the acoustic board, a large number of communicated tiny holes exist inside the porous fiber sound absorption material, and the sound waves can go deep into the material through the holes, generate friction with the material and converts sound energy into heat energy. After impacting the surface of sound insulating material, the sound waves penetrating through the porous fiber sound absorption material are reflected to the porous fiber sound absorption material and generate secondary friction with the material, sound energy is converted into heat energy again, and thus the sound insulating effect is achieved.
