What do you think are the applications of acoustic walls?

Acoustic wall elastic line positioning: According to the construction drawings, release the position control line of the movable partition wall on the indoor ground, and lead the partition wall position line to the side wall and roof. Acoustic wall track fixtures installation:

Select the track fixings according to the design requirements. Before installing the track, it is necessary to consider the closing method of the wall, ground and ceiling and facilitate the installation of the movable partition wall, and determine the load borne by the track and the specifications and fixing methods of the embedded parts by calculating the weight of the movable partition wall. The embedded parts of the track should be installed firmly, the track and the main structure should be fixed firmly, and all metal parts should be treated with anti-rust.

Prefabricated partition sash for sound insulation wall: First, determine the net size of the movable partition wall according to the design drawings combined with the actual measured dimensions on site. Then, according to the installation method of the track, the net size of the movable partition wall and the design grid requirements, calculate and determine the size of each partition fan of the movable partition wall, and finally draw a large sample drawing for processing.

Definition of soundproof wall: refers to a wall-type structure set up to reduce the impact of noise on the normal life of residents. Also known as the sound barrier.

The use of soundproof walls: mainly used for highways, elevated composite roads, urban light rail and subway and other municipal transportation, power plant cooling towers, indoor studios with high requirements for sound insulation effects (recording studios, studios, etc.).

The function of the soundproof wall: the use of sound-absorbing materials on the wall to reduce the transmission of sounds.

Excellent sound absorption, effective control of sound reflection, smooth decorative surface, providing a strong sense of art. Losay Acoustics.

Acoustic walls play an important role in protecting against outside noise. So what is the purpose of a soundproof wall? PChouse will take you to find out.

The soundproof wall not only isolates the entry of external sounds, but also keeps the sound in the room from leaking out, forming a good reverberation resonance environment and getting a good audio-visual experience. Acoustic walls work in both directions, whether you want to rest or relax, it can help. The function of the sound insulation wall is to reduce the crosstalk of each sound source in the recording room, or to adjust the sound quality of the sound source by using the different sound absorption characteristics on both sides of the wall panel.

At the same time, it can also play a decorative role in interior decoration, making the wall more beautiful and beautifying the indoor environment.

The main principle of the soundproof wall is to leave a buffer layer between the original wall and the soundproof wall, so that the noise is reduced through space and distance, and then the noise is converted into heat energy through the micropores in the sound-absorbing material, so as to achieve further reduction, so it can also have the effect of thermal insulation while making sound insulation.

The first choice for economic practicality is 2 4 red brick walls with cement walls on both sides. This kind of partition wall must be built to the top, and it is necessary to drill holes through the air pipe or when it is routed, and you should pay attention to the sealing problem of the pipeline, otherwise it can also cause crosstalk. The second is the soundproof wallboard, this material belongs to the professional soundproof material, both sides are metal plates, and the middle is a foamed plastic with sound insulation, the greater the thickness of this wallboard, the better the sound insulation effect.

In some places, because of the problem of bearing weight, can not use brick wall or other wall building methods, can only use the method of light steel keel gypsum board, our suggestion is to add a layer of cement board with higher hardness outside the gypsum board, the appearance of this cement board and gypsum board is the same (the size of the Zen is also about the same), but the hardness is much higher than the gypsum board, is a good sound insulation material, should pay attention to the construction process topic, especially the gap of the department must be sealed.

The method of checking the sound insulation effect is to measure the attenuation of the sound at one meter at the door, for example, the sound pressure level in the room is 90db, and the sound pressure level measured at one meter outside the room is 60db, which means that the sound insulation is 30db.

The treatment of the door of the room is also a difficult topic of decoration design, the treatment of the door of the recording studio is professional, the sound insulation effect is very good, but the cost is very high, usually a soundproof door is less than 4 5,000 yuan, more than 10,000 yuan. At present, it is more practical to adopt the method of forming an integrated door and adding a sealing strip to the side of the door, and the sound insulation effect of the door closer is not bad (compared to ordinary doors).
