whether it is home decoration or public decoration, sound insulation is very important. This forces us to choose suitable materials to absorb decorative sound. So what are the decorative shapes of the wall materials of the exhibition hall? The following is a detailed introduction. Introduce the wall materials of the exhibition hall

At present, the most commonly decorated wall materials of the exhibition hall are: solid wood board, wood wool of sound-absorbing board, sound-absorbing cloth board and sound-absorbing polyester fiber, which are widely used for sound absorption in concert halls, theaters, study rooms and listening rooms. In public places, such as conference rooms, fitness centers, exhibition halls, dance halls and KTV rooms, they can absorb noise and prevent internal sounds from reflecting and affecting the environment.

The sound absorption of two types of panels, namely, the wall material of the exhibition hall and the wood perforated with sound insulation board, is that the MDF perforated in the front slot absorbs sound, and the material slit in the vibrating wood tank rotates, or the sound absorption board is a density structure of wood pores, and the sound absorption material has round holes in the front and back of the board.

The fabric sound-absorbing board is made of special nonflammable microporous sound-absorbing surface and placed in a plastic or wooden frame. It is made of fabric that absorbs fire-proof sound, and has the characteristics of fire prevention, no dust pollution, strong decoration and simple structure. Decoration form of exhibition hall wall material

1. Exposed type: the exhibition hall wall material is directly arranged on the inner surface of the auditorium. For example, fabric sound-absorbing panels or polyester fiber sound-absorbing panels and sound-absorbing structures are arranged under the keel of a wall or ceiling.

2, decorative type: that is, the sound absorption of the surface material is made of various materials and decorative structures that meet the requirements of decoration, such as the sound absorption ecological wood wall of the mounting plate.

3. Concealed type: behind the sound barrier, several sound insulation blankets or various materials or sound insulation structures are arranged.

sound originates from the vibration of objects, which causes the vibration of adjacent air to form sound waves and propagate in the air environment. When the sound is transmitted to the surface of the material component of acoustic energy, it is reflected, and a part of it penetrates into the wall of the exhibition hall, and the material and the component rub against the surrounding medium. Because of vibration or sound component, the material and acoustic energy are converted into heat energy, and the acoustic energy is lost.

It is very important to choose the wall material of the exhibition hall. For sound absorption, it will have different forms. I hope you can understand the above summary.
