If the sound insulation is good, which plates are better

Hello, if you want an environmentally friendly board and sound insulation, you should choose more inorganic sound insulation boards, inorganic materials are generally environmentally friendly, such as glass, marble, tiles and other traditional materials The environmental performance is very good. Therefore, the sound insulation board should also choose these inorganic substrates. For example, honeycomb ceramic sound insulation panels and composite damping sound insulation panels are all of this category.

Types of acoustic panels.

1. Wooden sound-absorbing panels.

Wooden soundproof panels are made of strips of wood, and there are two main shapes of wooden sound-absorbing panels: grooved wood and hole wood. Because the wooden sound-absorbing board has a good thermal insulation effect, it is mostly used in soundproof places that need to be warmed and closed, such as halls, conference rooms, hotels, computer rooms, office buildings, and other sound-absorbing and confidential construction places.

2. Mineral wool sound-absorbing panel.

This is a kind of soundproof board with a very rich variety of surface forms, which can be changed at will according to the needs and has a good decorative effect. There are many holes of different shapes and styles on the surface of mineral wool acoustic panels, which can be widely used in theaters, KTV boxes, theaters, indoor sports venues, entertainment building sound construction, etc.

3. Fabric sound-absorbing panels.

The main material of fabric soundproof board is centrifugal glass wool, which has a good sound absorption effect.

4. Polyester fiber sound-absorbing panel.

This is a very good acoustic insulation board with very good fire performance and thermal insulation. And it has the characteristics of moisture-proof, mildew, dust removal, good stability, corrosion resistance, stamping resistance, etc., and is mainly used for professional space sound quality construction such as recording studios, studios, listening studios, dance studios, and rehearsal venues.

There are many soundproofing materials used in decoration, the more common ones are solid bricks, reinforced concrete walls, gypsum board, foamed aluminum, fiberboard and so on. In fact, there is no good or bad sound insulation material, only the strength of the sound insulation effect. What materials are good for sound insulation?

Everyone has a different opinion, and the sound insulation materials that are suitable for everyone's home are different, so you can choose appropriately. When decorating a soundproof wall, it is important to consider the sound insulation effect, fire prevention effect, radiation protection effect and toxicity effect of the material itself. The sound insulation material is better, I think you can use aluminum foam material, it has low density, high impact absorption ability, high temperature resistance, strong fire performance, corrosion resistance, sound insulation and noise reduction, strong weather resistance, filtration ability, high forming accuracy, and can be surface coated.

In addition to having a good sound insulation effect, foam material is also environmentally friendly, non-toxic and non-combustible, this lightweight, strong and not afraid of fire can be used for the veneer of elevator doors, the laying of train and subway car floors.

1. Soundproof felt.

Acoustic felt is a kind of high-density membrane with a certain flexibility made of elastic materials such as rubber and plastic as the main raw materials, which is mainly used to match gypsum board, used for wall sound insulation and ceiling sound insulation, and is also used for sound insulation and damping and vibration damping of pipelines and mechanical equipment. The application range of sound insulation felt is generally speaking, as long as it is used for sound insulation measures, it can be used, such as sound insulation felt plus gypsum board can be used as sound insulation wall, ceiling sound insulation is also used for sound insulation felt, and it is also used for sound insulation and damping and vibration damping of pipelines and mechanical equipment. Therefore, there is no doubt about the sound insulation effect of sound insulation felt.

2. Sponge. Sponge is a very good sound-absorbing material, and it is usually used in large quantities in recording studios to achieve sound insulation. The sponge with a sound-absorbing groove on the surface has a better sound absorption effect, and this kind of sponge is often called wave cotton. It's just that the sponge has strong water absorption ability and is easy to absorb dust, if it is used as a soundproof material for windows, it is easy to absorb water on rainy days or when wiping with a damp cloth, so that the iron frame on the window is rusty, but now many people's windows are not drenched in rain, so it is still very practical, and you can also consider it again when choosing.

3. Polyurethane foam.

Polyurethane foam is the main component of styrofoam. Cured polyurethane foam material can play a better role in sound insulation, sound absorption, and anti-corrosion, waterproof, and better polyurethane material has a flame retardant design, is a good choice of sound insulation materials.

4. Calm soundproof and sound-absorbing cotton.

Calm soundproofing sound-absorbing cotton is based on industrial rubber and plastic, adding a variety of specifications of soundproof particles, nitrogen foaming molding, gray-black appearance. Its front is covered by miniature sound-absorbing holes and special-shaped sound-absorbing grooves, which can efficiently filter noise of different frequencies and wavelengths, integrate sound insulation and suction functions, and meet the requirements of lightweight and environmental protection of home decoration sound insulation materials, and are very cost-effective.

5. Sound insulation damping felt.

Sound insulation damping felt is the introduction of foreign advanced technology by a variety of organic minerals in accordance with a certain proportion of refined, sound insulation felt has good broadband sound insulation performance and high damping performance, is a new type of sound insulation material to control the attenuation of noise in the transmission path. After the mixing of high-density special materials, a very good sound insulation and noise reduction effect is achieved, so that the sound insulation felt shows excellent performance in isolating air sound and impact sound, and the sound energy is lost in the sound insulation material, and it has an incomparable effect on the isolation of medium and low frequency noise, which is an excellent multi-purpose sound insulation material.

6. Insulating glass.

The insulating glass is composed of two or more layers of flat glass, and the two or more pieces of glass are bonded with an aluminum alloy frame or rubber strip with a high-strength and airtight composite adhesive around the perimeter, leaving a space between the sealing glass, and filling with inert gas to obtain excellent thermal and sound insulation performance. Due to the poor heat transfer of the air or gas trapped in the glass room, the superior sound insulation effect is produced.

To make the room soundproof, you need to consider the soundproofing of these places, first, the soundproofing of walls, ceilings, floors, etc.; the second is that the windows are made soundproof;

The wall sound insulation project is also a concealed project, which is generally constructed in front of the decoration. Once the renovation works are completed, there is basically no remedy, and the cost of remediation is very high. The sound insulation effect of the house also directly affects the quality of life, such as the sound of cars on the highway, such as the sound of neighbors walking, talking, and children's noisy sounds, all of which will affect our rest and leisure quality.

And the occurrence of these events is uncontrollable, except for the resolution before the renovation, which can only be endured after the renovation.

Usually suspended ceilings, walls facing the road, windows, walls in bedrooms and living rooms, partition walls in bedrooms and bathrooms, etc., are places that need to be soundproofed. There are two factors that affect the sound insulation effect, one is the structure of the sound insulation wall, and the other is the sound insulation material chosen.

Let's start with the soundproofing material:

Glass wool, rock wool, sponge should not be considered in the scope of indoor sound insulation materials, glass wool and rock wool due to their raw materials are brittle fibers, will be easy to enter, thus causing allergies, and their layered into the room will cause respiratory allergies. Sponges are flammable products that produce toxic gases when burned. Although they are all porous materials and have a certain sound-absorbing function, they have a low energy-absorbing efficiency, so they are not recommended.

Polyester fiber sound-absorbing cotton is a choice, its environmental performance is E1 level, and the fire protection level is B1 level, which has a better sound absorption effect for medium and high frequencies. However, due to the limitation of its material structure, the absorption of low-frequency sound is poor, such as the noise generated by electrical appliances, such as the mopping sound generated by the slippers upstairs, such as the noise of the neighbor's stereo caused by the wall, and the vibration sound generated by the ground are difficult to eliminate.

I recommend gradient sound-absorbing cotton, which is also polyester sound-absorbing cotton, so it has the environmental protection and flame retardancy of ordinary polyester sound-absorbing cotton, but it is different from ordinary polyester sound-absorbing cotton. Its density is step-incremental, not uniform. The upper side is softer and the other side is harder.

Generally, the soft side is oriented towards the sound source. Its structure can ensure that it absorbs low-frequency, medium-frequency and high-frequency sounds at the same time, and has high sound absorption efficiency.

The general practice of soundproofing partition walls or suspended ceilings is the same. Usually 5cm keel (wood or light steel can be), the hollow position in the middle of the keel is filled with 5cm thick, kilogram square meters of gradient sound-absorbing cotton, and the outer seal gypsum board. Generally, the family can meet the requirements with 5cm of high-efficiency sound-absorbing cotton, and gypsum board can usually isolate 20-30 decibels of noise, if there are special requirements, you can use two layers of 5cm thick gradient sound-absorbing cotton, and gypsum board can usually isolate 30-40 decibels of noise.

Second, the window sound insulation needs to choose a plastic steel or glass fiber reinforced plastic window frame with good sealing, if the window facing the highway side, you can install double glazing. Glass and window frames need to be sealed.

3. The pipeline can be torn apart with 5cm gradient sound-absorbing cotton to bundle the pipe, and the outside is all wrapped with tape, and the thickness of the soundproof layer is not less than 5cm thick.

1. There are various kinds of sound insulation materials, such as solid bricks, reinforced concrete walls, woodblocks, gypsum boards, iron plates, sound insulation felt, fiberboard, etc. There is no best or bad sound insulation material, only the difference between suitability and effect.

2. The so-called sound insulation material refers to the material that can isolate, isolate and separate the sound or noise and vibration sound, which is called sound insulation material. Because many places where people live have a certain degree of noise that affects normal life, it is necessary to have sound insulation materials to maintain people's normal life.

3. The sound insulation follows the principle of the law of quality, that is, the greater the unit density of the sound insulation material, the greater the sound insulation volume, and the areal density is proportional to the sound insulation volume.

Acoustic insulation materials are physically elastic and excite vibrations to propagate within the compartment when sound waves are incidence. When the sound wave is not perpendicular incidence, but is incident at an angle with the compartment, the sound wave front reaches the surface of the compartment layer sequentially, and the sound wave that first arrives at the compartment excites the bending vibration wave in the compartment to propagate laterally along the compartment, if the bending wave propagation speed is consistent with the travel speed that the sound wave in the air gradually reaches the surface of the compartment, the sound wave strengthens the vibration of the bending wave, and this phenomenon is called the anastomosis effect. At this time, the radiance of the bending wave vibration is particularly large, and the energy of the sound wave radiated to the air on the other side is also particularly large, thus reducing the sound insulation effect.

There are many kinds of sound insulation materials, and the common ones are: building sound insulation materials, KTV sound insulation materials, decoration sound insulation materials, sound insulation and vibration absorption materials, shock absorption and shock reduction materials, sound absorption and decoration materials, decorative sound absorption cotton boards, sound insulation boards, sound insulation and fire protection materials, etc.

Common specifications and thicknesses: type sound insulation materials, type sound insulation materials, type sound insulation materials, etc.

For home wall sound insulation, you can use gradient sound-absorbing cotton, using 100% imported polyester fiber, using laminated lamination, strictly controlling the pressure of lamination, so as to generate panhoo gradient sound-absorbing cotton from soft to hard between layers, which has a good absorption effect on noise of various frequencies.

Matters added: gradient sound-absorbing cotton completely solves the limitation that ordinary polyester fiber sound-absorbing cotton can only eliminate the middle and high frequency sounds such as speaking sounds, and realizes the good absorption of low-frequency sounds generated by electrical appliances, ground and wall vibrations, and slippers mopping the floor. So the panhoo gradient sound-absorbing cotton we provide is not only a safe sound-absorbing cotton, but it is also a high-efficiency sound-absorbing cotton. It is widely used in sound insulation and sound attenuation of partition walls, suspended ceilings, floors, machinery and equipment.

Its excellent performance is unmatched by other sound-insulating and sound-absorbing materials.

01 Sound insulation materials refer to a kind of materials, components or structures that can block sound transmission or weaken transmitted sound energy, which are characterized by heavy quality and high density, such as steel plates, lead plates, concrete walls, brick walls, sound-absorbing cotton, wood wool sound-absorbing panel waves, peak sound-absorbing sponges, etc., which materials are best used to look at the environment.

Sound insulation refers to isolating, isolating, separating, etc. from sound or noise through certain items, so the need for sound insulation is to transport materials indiscriminately. The number of decibels of the incident sound energy on one side of the material in relation to the transmitted sound energy on the other side is the sound insulation volume of the material, usually expressed in the symbol r(db). Available:

Steel plate, lead plate, concrete wall, brick wall, sound-absorbing cotton, wood wool sound-absorbing board wave, peak sound-absorbing sponge, etc., which material is best used to look at the environment.

Sound insulation materials or components will not be the same due to different use occasions and different test methods. For sound insulation materials, in order to weaken the transmitted sound energy and block the transmission of sound, it cannot be as porous, loose and breathable as sound-absorbing materials, on the contrary, its material should be heavy and dense, such as steel plates, lead plates, brick walls and other materials. The quality requirements of sound insulation materials are dense and no pores or gaps; There is a large weight.

Because this kind of sound insulation material is dense, it is difficult to absorb and transmit sound energy and the reflection energy is strong, so its sound absorption performance is poor.

1. Sound-absorbing cotton.

Sound-absorbing cotton is a common soundproofing material that is widely used in noisy public areas such as theaters, recording studios, KVTV, hotels, etc. At the same time, the processing of sound-absorbing cotton is relatively simple, and it has excellent moisture-proof, waterproof and breathable properties. However, the flame retardancy of sound-absorbing cotton is relatively poor, and it cannot effectively prevent the spread of fire.

2. Wood wool sound-absorbing panel.

Wood wool sound-absorbing board is also a more popular soundproof material, wood wool sound-absorbing board is made of poplar wood fiber as the base material, the texture is outstanding, bringing people a sense of natural freshness, at the same time, the wood wool sound-absorbing board is simple to decorate, looks more high-end atmosphere, excellent sound absorption effect, often used in the hall, opera house and other places with high requirements for sound quality.

3. Wave peak sound-absorbing sponge.

Wave peak sound-absorbing sponge is a kind of soundproof material that many people will choose, its surface is specially treated with equipment, so as to form a concave and convex wave-like sponge, it has many small voids inside, can inhale a large number of sound waves, and play a fixed attenuation role in the volume.
