I m going to open a bar and want to know how to do soundproofing

Many people know that solid wood doors have better sound insulation performance than other materials, and its sealing is also important. If the sealing is good, the noise will be smaller, and if the sealing is not good, it will not play a sealing role. If we take solid wood doors and solid wood composite doors as an example, the higher the density of the wood itself, the heavier the weight, and the thicker the door panel, the better the sound insulation effect, and the simpler it is to reduce noise pollution.

1. The best way to deal with noise is to solve the problem of window leakage first. 2. The window sealing is solved, and the next step is to strengthen the sound insulation of the door, and the sound insulation of the door does not mean that it is thickened, but also depends on the sealing performance. 3. Improve the sound absorption and sound insulation performance of the wall.

4. In addition, the use of thick curtains can also consume part of the sound energy, which is also a relatively simple way, using carpets, fabrics and even sound-absorbing (insulation) cotton to reduce the impact of part of the reflected sound on the room. 5. Of course, no matter how to do sound insulation, you can't forget ventilation, too closed environment is not healthy for the human body. On the noise-oriented side, noise prevention should be designed.

6. Due to the vibration characteristics, the use of vibration-absorbing materials, such as damping sound insulation felt, vibration-absorbing glue, vibration damper and other materials, can weaken the resonance and anastomosis effect of the wall and the decoration board, so as to improve the sound insulation performance.

Bars are generally located near residential areas, and access passages, fire doors, and air conditioning exhaust vents may become the release and leakage points of the bar's sound waves, affecting nearby residents. How to insulate such a bar decoration? Let's tell you about Jumao sound insulation:

1. The soundproof entry and exit passage of the bar is designed as a sound gate structure. In reality, most bars have only one door, and no matter how well soundproofed the door is, it is inevitable that the sound waves of the bar will leak during the time when guests enter and exit the switch. Therefore, the design should add a soundproof door at a distance of not less than the original door, so that the first door is closed when the guest opens the second door, and the sound wave cannot be discharged.

2. Door cracks, thresholds, and door bumps reduce sound leakage. Excessive door gap greatly reduces the sound insulation effect of the door, so it is necessary to use adhesive strips to design a closed structure in these parts, and ensure that sound waves cannot leak from the gaps through the compression of the adhesive strips and air compression deformation.

3. Install a broadband muffler at the exhaust port. Air conditioners and exhaust outlets will bring out the noise during the discharge process. It is necessary to install a composite muffler, and under the premise of not affecting the normal exhaust, the low and low frequency sound waves in the high-level decoration and renderings will be basically eliminated in the high-level decoration and renderings to provide the most abundant home decoration design and renderings.

4. Bar sound absorption: Sound absorption soft package is added in the bar. Bar walls, sofas, and seats should be made of sound-absorbing materials to reduce the sound pressure of the indoor sound field, and at the same time, the volume and tone of the bar can be adjusted to be more harmonious and beautiful.

You can refer to the following points to do so.

1) To improve the sound insulation of the wall, first solve the problems of the wall itself not closed, holes, etc.; According to the law of quality, usually the mass of the wall increases by half and its sound insulation will increase by 6db, but the use of reasonable sound insulation materials and structures can be changed, magnesite peak nest sound insulation board, magnesite low frequency sound insulation board and other sound insulation boards, which can greatly improve the sound insulation performance of the wall.

2) Solve the problem of sound leakage of doors and windows, such as early rot, most bars are using ordinary doors or soft package doors, in the high-noise environment of up to 105db or more in the private room, sound insulation is obviously not enough, the solution can be to use sound insulation doors, or design double doors, to form a "sound gate" sound insulation structure, the effect is remarkable.

3) The sound absorption and sound insulation design of the ceiling is essential, and the high noise in the bar is transmitted in all directions, which can also be called random incidence, and some speakers are hung on the ceiling, so it is essential to strengthen the sound insulation and sound absorption of the ceiling.

4) The sound insulation and vibration reduction of the ground are very important, and the damping sound insulation felt, sound insulation floor, vibration isolator and so on can be laid.

5) The vibration reduction problem of the speaker should be strengthened, and the sound is generated by vibration, whether it is a full-range speaker or a multi-channel system, the low-frequency sound must exist, so it is necessary to do a good job in vibration reduction measures, which can generally be dealt with by means of vibration reduction hook and vibration reduction table.

6) Other, air conditioning ventilation noise problems are best treated with a muffler. The natural vibration of the air conditioning duct can be fully treated with damping acoustic felt.

Which company to find in the soundproof room, the sound factory specializes in scientific research and development, product manufacturing, acoustic design and construction, as one of the high-tech enterprises, to improve the good acoustic environmental protection environment as its own responsibility, is specialized in noise control and research. The business includes acoustic design, production of acoustic materials, sound insulation construction, and sound insulation on-site technical support.

1.The sound insulation renovation of the wall can effectively and reasonably reduce the impact of noise on the outside world2Ground sound insulation renovation can prevent the transmission of noise generated by vibration3Ceiling acoustic insulation can reduce the impact on the surroundings.

4.Sound insulation renovation of downspouts, downspouts and fire hoses are treated with damping and bandaging to prevent noise from spreading5The ventilator is equipped with an exhaust muffler, and the ventilation pipe is soundproofed.

The three major aspects of bar noise control are ceiling sound insulation, wall sound insulation, floor vibration reduction and sound insulation, 1. The elimination of low-frequency vibration is necessary for vibration reduction and sound insulation from all points and surfaces, and the low-frequency noise generation is reduced on the bar noise source.

2. Reduce the leakage of sound waves, increase sound-absorbing materials in the bar wall, install mufflers in the exhaust device 3, and separate the vibration-isolating steel structure of the bar card seat from the structural wall column and beam.

1. Bar wall sound insulation treatment plan:

First of all, a layer of vibration damping pad and sound insulation felt is glued on the original wall, a light steel keel is added, the keel cavity is filled with a layer of sound insulation cotton, and then the wood bolt is sealed to dampen the sound insulation board. After that, the exterior is made of polyester acoustic panels. Achieve the effect of external sound insulation and internal sound absorption.

Second, the bar ceiling soundproof decoration plan:

First of all, install the shock absorber on the ceiling floor, and the suspension bar should be treated with a vibration damping hook, and the light steel keel should be played, and the keel cavity should be filled with a layer of sound insulation cotton, and then the composite damping sound insulation board should be installed. After that, a layer of soundproof cotton is covered. Finally, a composite damping acoustic panel is installed to ensure the sound insulation effect.

3. Decoration plan for sound insulation and vibration reduction on the ground of the bar:

1. First level the original ground and seal the holes;

2. Lay floor slab shock-absorbing pads on the original ground. When laying the vibration damping pad, the ground should be cleaned up, and the debris on the ground should be avoided as much as possible to cause damage to the sound insulation material, and the trimming should be done in advance;

3. Tile soundproof felt above the vibration damping pad;

4. Then lay a layer of 30mm damping plate;

5. Pour a concrete layer with a thickness of 50mm above and add reinforcement inside;

6. The surface can be leveled.

If a bar wants to retain guests, first of all, it is necessary to do a good job of soundproofing the bar, so how does the bar do soundproofing? Doing sound insulation is a test of technology and experience, and you can find a professional sound insulation company to help you. The following Jumao sound insulation will tell you a few small experiences in sound insulation:

Soundproofing is solved"Crosstalk"Theoretically, the harder the material, the better the sound insulation. The most common decoration method is the light steel keel gypsum board partition wall, although the sound-absorbing cotton is put in the middle, but due to the lack of quality, the sound insulation effect is very poor, most of the bars are using this decoration method, the sound insulation effect is not good.

So what kind of material is good for sound insulation? The first choice for economic use is a red brick wall with cement walls on both sides. This kind of partition wall must be built to the top, and then punch holes through when you need to walk through the ventilation duct or other wiring, and you should pay attention to the sealing problem of the pipeline, otherwise it can also cause crosstalk.

The second is the sound insulation panel, the thicker the wall panel, the better the sound insulation effect. In some places, due to 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 is the same as gypsum board, but the hardness is much higher than gypsum board, it is a good sound insulation material, it should be noted that the construction process problem, especially the part of the gap must be sealed.

1.The sound insulation renovation of the wall can effectively and reasonably reduce the impact of noise on the outside world2Ground sound insulation renovation can prevent the transmission of noise generated by vibration3Ceiling acoustic insulation can reduce the impact on the surroundings.

4.Sound insulation renovation of downspouts, downspouts and fire hoses are treated with damping and bandaging to prevent noise from spreading5The ventilator is equipped with an exhaust muffler, and the ventilation pipe is soundproofed.

The sound insulation of the bar per square meter should be considered according to the sound insulation materials used in the bar, the luxury of decoration, the difficulty of construction and other comprehensive factors. If you want to know clearly the best of your bar soundproofing decoration, then you must first clarify what kind of soundproofing materials you want to choose, the beautiful decoration of the bar, and the remuneration of construction workers per square meter. Then the sum of these three is almost the sound insulation of the bar room per square meter**.

Among them, the remuneration of workers generally does not play a decisive role, and as long as the beautiful decoration is not luxurious, it is also in a stable range. In the end, it is the soundproofing material that determines the cost of soundproofing in this bar. After all, the difference in sound insulation materials may vary by tens of years.

A square tens, so how much is a bar? Therefore, this problem is also very difficult to solve the problem of sound insulation materials, although there is the word cheap and good, but it is almost impossible to be cheap and good in the sound insulation materials in actual life, because the current domestic sound insulation material production is the penny of the penny to determine the sound insulation material. 4008-593--935 Jumao acoustic sound insulation design and construction.

The bar has the necessary shock absorption and sound insulation from all points and surfaces to meet the design requirements.

1. Ceiling: vibration damping hook + keel + sound-absorbing cotton + soundproof felt + soundproof board, if the sound source is larger, the ceiling needs to be double-layer soundproof ceiling.

2. Wall: heaven and earth keel + sound-absorbing cotton + soundproof felt + soundproof board, if the sound source is larger, the wall needs to be double-layer sound insulation.

3. Ground: soundproof felt + shock absorbing pad + concrete.

4. Reasonable layout of speakers to reduce mutual interference. Do not hang the speaker directly on the wall or on the ground, you can use an elastic hook or vibration damping pad to make the speaker and the building flexibly connected.

5. Replace doors and windows with soundproof doors and windows, and pay attention to good sealing.

The bar soundproof wall needs to use shock-absorbing keel, shock absorber, damping soundproof felt, damping soundproof board, and fireproof fiberglass soundproof cotton to achieve a better soundproof effect.

To do a good job of soundproofing a bar, it depends on which series of materials you want to use. For example, the two methods generally used for bar sound insulation are the sound shield sound insulation series and the sound insulation K-18 spraying series. Their construction methods are simple, effective and cost-effective.

So some bar owners prefer to use both options. If I suggest it, it's best to do both of these methods together, so that the effect will be better.

The ceiling should be soundproofed and shock-absorbed, so sound-insulating plates, sound-insulating cotton, and shock-absorbing dampers and damping glue will be used.

To do bar sound insulation, we must be clear that the noise comes out, and then according to the noise of the noise, the use of targeted sound insulation materials and the use of inorganic fiber spraying together, in order to reflect the high-quality effect. The landlord can take a look, there are a lot of things about the bar soundproofing solution, and what kind of situation, what kind of sound-absorbing soundproofing materials to choose. Hope it helps.

The bass must be treated strictly, including the corners and ventilation ducts at every corner. Usually the denser the material, the better the sound insulation, that is, the heavier the guy, the better. If space permits, we will recommend a room-within-a-room form; Make sure the bar doesn't affect the surrounding residents.

The use of sound-absorbing and sound-insulating cotton K-18 spraying, economical and cost-effective, is much lower than the traditional sound-absorbing material soundproof material, directly sprayed on the ceiling, glass, steel pipe, wall, etc. of complex structures, simple construction, perfect combination with the original pattern of the building, but also greatly reduced the construction time. What's more, a variety of colors are available, which is completely in line with the designer's design style. Or in terms of sound absorption, sound insulation, fire performance, etc., sound-absorbing cotton K-18 has incomparable advantages over traditional acoustic materials, and has achieved the original intention of the owner's sound upgrade.
