Sound absorption plate for sound insulation room

Abstract

The invention relates to a sound-absorbing panel for a sound-proof room, which comprises a sound-absorbing panel body. One side of the sound-absorbing panel body is provided with an anti-collision layer made of PU foam, and one side of the anti-collision layer is provided with a sound-absorbing layer made of glass fiber sound-absorbing cotton. The sound-absorbing layer is provided with a plurality of first sound-absorbing ribs and a plurality of second sound-absorbing ribs. There is a reinforcement member, the reinforcement member includes a first reinforcement board and a second reinforcement board, the first reinforcement board is arranged vertically inside the sound-absorbing panel body, the number is one, and it is located in the center of the sound-absorbing board body, and the cross-section of the first reinforcement board is sawtooth shape; the second reinforcing plate is horizontally arranged inside the sound-absorbing panel body, and there are two in number, located at the upper and lower parts of the sound-absorbing panel body, and the cross-section of the second reinforcing plate has an S-shaped structure. The invention has the advantages of simple structure, high strength and good sound-absorbing effect.

Description

technical field [0001] The invention relates to a sound-absorbing panel, in particular to a sound-absorbing panel used in a sound-proof room. Background technique [0002] The acoustic laboratory is a special laboratory for simulating various ideal sound field conditions and measuring various parameters to study the law of sound wave propagation and the sound absorption, sound insulation and noise reduction performance of building materials, building structures, and building components . It is mainly used to simulate the diffusion sound field, free sound field and the propagation of sound waves in the pipeline, etc. There are reverberation chambers, anechoic chambers, soundproof rooms, etc. In the prior art, the sound-proof room of the acoustic experiment adopts built-in sound-absorbing panels for sound-absorbing. However, due to the simple structure of the current-stage sound-absorbing panels, most of them are simply cut and made of sound-absorbing materials. Get great re...
