Shock-absorbing and noise-reduction sound-proof room

Abstract

The invention relates to a shock-absorbing and noise-reducing sound-insulating room, which comprises four side walls, a bottom plate and a top plate, and is characterized in that a shock-absorbing pad made of rubber elastic body is laid on the surface of the bottom plate of the sound-insulating room, and the shock-absorbing pad is passed through a screw fixed on the bottom plate of the sound-proof room; the surface of the side wall and the top plate inside the sound-proof room is provided with a shock-absorbing layer made of PU foam by gluing; the surface of the shock-absorbing layer is provided with a sound-absorbing board, The sound-absorbing board includes a sound-absorbing board body, an anti-collision layer made of PU foam and a sound-absorbing layer made of glass fiber sound-absorbing cotton. The invention has the advantages of simple structure, high strength and good shock and noise reduction effect.

Description

technical field [0001] The invention relates to a sound-proof room, in particular to a shock-absorbing and noise-reducing 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 resu...

Problems solved by technology

In the prior art, the sound-proof room for acoustic experiments uses built-in sound-absorbing panels for sound-absorbing. However, due to the simple structure of the current sound-absorbing panels, most of them are simply cut and made of sound-absorbing materials. get great results

[0003] At present, the structure of the soundproof room is simple, and it is often difficult to achieve the effect of shock absorption and noise reduction. Therefore, the development of a soundproof room with good shock absorption and noise reduction effect has attracted more and more attention.
