What is the sound insulation principle of acoustic glass?

The sound insulation principle of soundproof glass is:Various outdoor sound sources produce vibration and make noise, and the noise is transmitted through the air medium, and when the noise is transmitted to the soundproof glass doors and windows, it is attenuated by the soundproof glass one by oneEspeciallyWhen the noise passes through the sound insulation damping glue, the medium frequency noise and low frequency noise are absorbed, distorted, shocked and attenuated by the sound insulation damping glueIt can effectively filter out the medium and low frequency noise, and the noise that finally enters the room is only about 5%.

The most common, annoying, annoying, and sleepless "chirp" and "ho-ho" medium and low-frequency noises are basically gone, and they are not very audible, and the feeling of the room has softened all of a sudden, and it is much more comfortable to stay indoors.

As sound waves propagate through a medium, the sound wave energy inevitably weakens gradually as the distance increases. The so-called soundproof glass is just a special medium that greatly weakens the energy of sound waves.

The principle of sound insulation glass to produce sound insulation effect: outdoor various sound sources vibrate to produce noise, noise is transmitted through air medium, when the noise is transmitted to the sound insulation glass doors and windows, and then attenuated by the sound insulation glass one by one, especially when the noise passes through the sound insulation damping glue, the medium frequency noise and high frequency noise are absorbed, twisted, shock absorbed, attenuated by the sound insulation damping glue, which can effectively filter out the medium and high frequency noise, and the noise entering the room is only about 5%.

At present, soundproof glass can be roughly divided into three categories according to the different production processes: insulating glass, vacuum glass, etcLaminated glass. When it comes to sound insulation, each type of glass has its own characteristics. Double glazing usually refers to insulating glass or vacuum glass. <>

Sound insulation principle: the principle of sound insulation glass to produce sound insulation effect: various outdoor sound sources vibrate to produce noise, noise is transmitted through the air medium, when the noise is transmitted to the sound insulation glass doors and windows, and then attenuated by the sound insulation glass one by one, especially when the noise passes through the sound insulation damping glue, the medium frequency noise and high frequency noise are absorbed, distorted, shock absorbed, and attenuated by the sound insulation damping glue, which can effectively filter out the medium and high frequency noise, and finally enter the indoor noise is only about 5%.

Sound insulation principle: sound insulation glass produces sound insulation principle: various outdoor sound sources vibrate and make noise, and the noise is transmitted through the air medium. When damping glue, mid-frequency noise and high-frequency noise.

The distance of soundproof glass is to block the transmission of sound, and the glass is generally thicker, so the sound cannot be transmitted.

Look at the outside world through doors and windows every day, but do you know the special features of the glass on doors and windows? Palaide soundproof doors and windows, here"Glass"Redefined, it's beyond your imagination! Glass is one of the important components of doors and windows, good doors and windows are inseparable from good glass, and good home environment and safety are inseparable from good doors and windows.

So what types of high-end doors and windows can be selected when choosing glass? What do they do?

Insulating glass. Insulating glass is a composite of two or even three layers of glass to change the propagation medium of sound waves, so that the energy of sound waves can be consumed, so as to achieve sound reduction, effectively block the entry of external sound, and achieve the purpose of sound insulation and noise reduction. In general, the thermal conductivity of the sealed middle air layer is much lower than that of normal glass, so the thermal insulation performance of insulating glass can be increased by a factor of two compared to monolithic glass. The glass design is optimized to achieve a super sound insulation effect, the hollow tempered glass is made of a combination of glass of different thicknesses, with inert gas, a large width of the hollow layer, a double sealant, and no resonance in the noise environment, making the space sound insulation experience excellent.

PVB laminated glass.

Laminated glass, also known as laminated glass, is made of two or several pieces of float glass sandwiched with a strong PVB adhesive film, which is pressed by a hot press at high temperature and high pressure. The addition of PVB film can change the propagation medium of sound waves, so that the energy of sound waves can be consumed, so as to achieve sound reduction and effectively block the entry of external sounds. Laminated glass is characterized by its multi-functional functions such as safety, heat insulation, ultraviolet protection, explosion resistance, and sound insulation.

Moreover, it can be widely used in building door and window glass, light shed, overhead ground, high-grade curtain wall doors and windows, furniture, aquariums, etc. Today, when product safety is becoming more and more important, it is widely used in high-end doors and windows, and is also loved by high-end residential and villa users.

Coated glass. Coated glass, also known as reflective glass, coated glass is coated with one or more layers of metal, alloy or metal compound film on the surface of the glass to change the optical properties of the glass to meet a specific requirement. According to the different characteristics of the product, coated glass can be divided into the following categories: heat reflection glass, low-e glass (low-e) It is mainly used in glass curtain walls, building doors and windows, automobiles, ships, etc.

Over the past 25 years, Paride doors and windows have been pragmatic and innovative, and in 2001, they developed the first series of imitation wood aluminum alloy doors and windows in China, which triggered the revolution of indoor doors such as kitchens, bathrooms, balconies, partitions, etc., and became a leader in the industry in green environmental protection, elegant fashion and technological innovation. Always be careful, sincere, confident, patient, persevering, and assured"Six hearts"For the service concept, to bring consumers more intelligent, more comfortable and more aesthetic door and window products. The doors and windows are made of insulating glass, which has strong functionality, which greatly improves the heat and sound insulation performance of doors and windows, just to bring you a better living experience, choose Palid doors and windows, and choose a high-quality living lifestyle.

Glass sound insulation is mainly because the density of glass is relatively large, when the sound penetrates the glass, there will be a certain degree of reduction and attenuation, as well as refraction phenomenon, at the same time, when the sound propagates on the surface of the glass, it will make the glass produce a certain vibration, and will also weaken a certain sound wave energy, so the glass will be sound insulation, at the same time, some new types of sound insulation glass use some new technologies, such as deva glass is processed with deva sound insulation damping film, and its sound insulation can be as high as more than 40 decibels.

The reason why the soundproof glass is soundproof is mainly because the resonance coefficient between the glass is adjusted, and there is a layer of deva soundproof damping film between the glass and the glass, the function of this soundproof damping film is to absorb the vibration of sound waves and reduce the transmission of sound waves, so for soundproof glass, the glass production and sound insulation are formed by the superposition of these two aspects, and the direct consequences of this resonance and noise-absorbing structure.

The sound insulation effect of ordinary glass is mainly because it slows down the sound propagation, because the sound must have a medium to propagate, and the vacuum cannot transmit, and the speed of sound propagation is gaseous liquid and solid respectively, and ordinary glass is solid, which can prevent the propagation of part of the sound wave and block the sound wave out of the glass. The soundproof glass is to use the characteristic that sound cannot be transmitted in a vacuum, and artificially create a vacuum space, that is, the soundproof glass is two-layered, and a layer of vacuum is separated between the two layers of glass, which prevents the transmission of sound. The more vacuumed this vacuum layer is, the better the sound insulation.

The sound insulation principle of soundproof glass is that various outdoor sound sources produce vibration and noise, and the noise is transmitted through the air medium, when the noise is transmitted to the soundproof glass doors and windows, and then attenuated by the soundproof glass one by one, especially when the noise passes through the soundproof damping glue, the medium frequency noise and low-frequency noise are absorbed, twisted, dampened and attenuated by the soundproof damping glue, which can effectively filter out the medium and low-frequency noise, and finally enter the indoor noise is only about 5%.

How many types of soundproof glass windows are there?

1. Hollow: It is a kind of glass that binds two or three layers of glass together through adhesive, this kind of glass is composed of multiple layers, and the sound insulation effect is general, which can only isolate the sound from a long distance, but the stability and thermal insulation are relatively good.

2. Ordinary: It is the worst kind of glass, basically only the role of sheltering from the wind and rain, if the surrounding environment is more installed, you can choose this ordinary glass.

3. Vacuum: Although there is only one word difference with insulating glass, this kind of glass has a very good sound insulation effect compared to insulating glass, and it is also the most professional soundproof glass, which is composed of two pieces bonded together.

How to choose a soundproof glass window?

1. Quality: Good quality selection is also very important. When purchasing in Machangru, it is necessary to see whether the materials and colors of aluminum alloy, glass and hardware are consistent, and whether the accessories are complete.

In particular, the process must be grasped well, and the high-quality materials are consistent in terms of lines, work and angles. Secondly, it is also necessary to pay attention to whether there is a plating layer on the glass and whether the size meets the standard.

2. Sealing: When choosing, we should pay attention to the sealing degree of the window, the most important thing to determine the sealing effect is the sealing strip, there are two kinds of sealing strips on the market, one is the wool sealing strip, which is easy to lose hair, which will reduce the sealing effect; The other is rubber sealing strip, which is easy to age and harden, which will also affect the sealing effect.

3. Window frame: From the perspective of sound insulation, aluminum alloy of window frame is a good choice, which is not only suitable, but also more convenient to install than Xunqi.

4. Material: The material is the most important thing to pay attention to when purchasing, and now the isolation glass material on the market is divided into three categories, these materials of glass have different properties and disadvantages, and we try to determine the actual needs and living environment of the layout as much as possible when purchasing.

With the step-by-step development of society, people's quality of life is getting higher and higher, more and more people like to spend a lot of money to buy high-rise buildings in the city, although life in the center of the city will seem to be very enjoyable, but with the increase of private cars, traffic noise is becoming more and more serious, and some areas have seriously affected the normal life of residents. Since you live in a city, it is impossible to live far from the place where you live, so people will definitely devise some good ways to solve a series of problems in this regard.

Today to bring you is soundproof glass, I believe you will understand as soon as you hear this name, soundproof glass is the sound outside the glass will be isolated, will not be transmitted to the room, check some of the principle of soundproof glass, listen to you in detail about the soundproof glass.

There are three main categories of soundproof glass, insulating glass and vacuum glass and laminated glass, and soundproof glass is so distinguished because they have great differences in the manufacturing process. Moreover, these three types of glass have different characteristics, so let's talk about the differences between these three kinds of soundproof glass.

Insulating glass, as the name suggests, is empty in the middle of the glass, but the glass is sealed with a high airtight binder around it, and the empty gas in the middle is dry, and it has a certain thermal insulation effect. Vacuum glass, there must be many people who think that insulating glass is the same as vacuum glass. But there is still a difference between them, in essence, the vacuum of the middle layer of the vacuum glass will be evacuated to allow the two pieces of glass to be successfully sucked together, so that they lose the original vacuum layer, the insulation performance of vacuum glass is better than that of insulating glass, and the sound insulation effect is more obvious.

Let's talk about laminated glass, it is also known as laminated glass, some laminated glass will be easy to blister under the sun exposure for a long time, which will make the sound insulation effect of this kind of glass lacking.

Then let me talk about the principle of sound insulation, all kinds of noise outside the glass are emitted by a certain vibration, the air is used as a medium to propagate, the noise comes to the window on that floor, because there are many layers of soundproof glass, so that the noise becomes a little weakened when it enters the room again and again, and the noise will be successfully filtered out, and finally only 5% of the noise arrives in the room. The slow noise, which sounds like a headache outside, suddenly softens with the help of soundproof glass, and does not make people feel annoyed.

There are many consumers due to the best reasons, thinking that as long as it is soundproof glass, it can be a good soundproof effect, but in fact, it is not, we can't buy something that is not substantial in order to save money.

I don't like this answer upstairs, it's ambiguous and I still can't understand it!

The principle of soundproof glass is not complicated at all, three different types of soundproof glass, among which the front glass of the hollow glass car is soundproofed by the air layer, the larger the air layer, the more sound insulation, the better, so the sound insulation performance of the three-glass two-cavity insulating glass is better than that of the single-cavity insulating glass.

Vacuum glass mainly relies on the vacuum layer to insulate sound, as we all know, sound needs medium propagation, the existence of the vacuum layer completely blocks the propagation path of sound waves except for the vacuum glass support point, so the biggest obstacle to vacuum glass sound insulation is the vacuum layer support.

Laminated glass relies on different media propagation rates to sound insulation, in fact, this statement is not entirely true, DEV soundproof glass is also Cong Fan laminated glass, it is the biggest difference with PVB laminated glass is the ratio of the original glass and the type of interlayer, PVB material requires the glass on both sides of the interlayer film to have the same flatness or curvature, and the infiltration of the Deva interlayer does not have such strict requirements, In fact, the DEV soundproof glass is far superior to PVB laminated glass by up to 30% at the same thickness, and there is no problem of cavity bubbles in the later stage. The principle of DEV soundproof glass relying on resonance interference friction conversion vibration potential energy is also more advanced than PVB laminated glass.
