| titleOfInvention | A kind of broadband composite acoustic board and the sound absorption wall being made of it |
| abstract | The sound absorption wall constituted the invention discloses a kind of broadband composite acoustic board and by it, sound absorption wall includes wall, the broadband composite acoustic board that is fixed on the lightgage steel joist of surface of wall and is fixed on lightgage steel joist, and resonance sound-absorbing chamber is formed between broadband composite acoustic board and wall；Broadband composite acoustic board includes particle acoustic board, and the surface of particle acoustic board is equipped with the cannular boss of several spaced certain distances, groove is formed between adjacent two cannular boss.The broadband composite acoustic board of the present invention and the sound absorption wall being made of it have many advantages, such as that acoustic frequency bandwidth, acoustic absorptivity are high, sound absorbing performance is good, good appearance, simple in structure, easy to make, manufacturing cost is low, construction cost is low, short construction period, highly promote the use of. |
