In order to reduce noise, it is good to close the doors and windows frequently

It's definitely not good, because if you keep the doors and windows closed, there is no fresh air coming in, and it's not so good for the body. But if the impact of the dry sound is relatively large, you can't turn it off.

First of all, there is no way to make no sound at all, noise can disappear, but noise is actually a very subjective concept, if you can eliminate noise, it is impossible to eliminate all sounds. The meaning of sound insulation is to reduce the sound environment to a comfortable range, not to have no sound at all, generally speaking, it is generally below 40 decibels.

Although fresh air ventilation is not as good as convection through open windows, it can isolate particulate pollution and noise, and it is enough to meet human needs. 50 square meters can control the CO2 at an optimal level.

General soundproof glass, close the doors and windows, the sound insulation effect is actually average, and the dust resistance is good. Either buy professional glass, or neutralize with "white pollution", have discernment to hear.

How do you ventilate and isolate noise from noise-reducing windows? The hustle and bustle of the city makes us a little tired, and we all want to have a quiet and comfortable home when we come home from work every day. But noise has become a big annoyance in our lives.

If you want to solve the noise, it is not that difficult, you only need to do window sound insulation. Let's take a look at the best ways to insulate your windows. Now the main use of double-layer hollow windows for sound insulation, this way will also have a certain effect of isolating traffic noise, but in terms of sound insulation effect, the more a soundproof window is worse.

<> the sound insulation film attached to the window, the sound insulation film is mostly a multi-layer structure, and the sound insulation resin is sandwiched between the polyvinyl butyral (PVB) layer. Insulating particles are evenly distributed throughout the interlayer. When using acoustic film on buildings, the high-performance interlayer sandwiched between the film has visible light transmission, so it does not reduce the visible light transmission of the building and maintains a clear line of sight.

Window soundproofing films are relatively inexpensive and serve a similar purpose to cell phone films.

Installing window sound insulation seals, sound insulation seals, is only effective for windows with poor sealing, ** is very cheap, but it is necessary to determine in advance that poor sound insulation is not the reason for the large gap in the window, otherwise it will be useless to paste it. The seal is to plug the cracks in the windows, like soundproof cotton. The device looks like a small speaker grid that can be connected to an open window.

If the sensor detects noise outside the window, the speaker inside the window emits a "reverse sound" at the same frequency as the outside noise to cancel out the noise and reduce noise pollution entering the room. Acoustic windows generally consist of double or triple layers of glass and window frames of the same material or different glass, and the glass used can be thicker than ordinary window glass.

Some soundproof windows are made of specially treated soundproofing layers, or composite glass components sandwiched between aluminum alloy boxes filled with desiccant and bonded with sealant on the edges; There is a pressure-resistant flat glass module that makes full use of the principle of a thermos flask, makes the transparent and light-balanced package, fills the window frame with sound-absorbing materials, fully absorbs the sound waves of the transparent glass, and isolates the noise of each frequency band to a greater extent.

How to ventilate soundproof windows.

1. How to ventilate the soundproof window window type ventilation device.

Types and advantages: A type of window type soundproof ventilator added to the window. This kind of soundproof ventilator uses a unique S-shaped channel to effectively absorb harmful noise and some dust, so that fresh air can flow into the room continuously to achieve the effect of ventilation and sound insulation; This ventilator guarantees fresh air all year round with the windows closed.

There are two types: natural and electric, with the following advantages::

1. Excellent sound insulation, with a sound insulation of 25-32 decibels.

2. Two-way ventilation to circulate and flow indoor air.

3. The configuration is flexible, and the most reasonable location can be selected according to the characteristics of the building.

4. Safe and reliable, using German technology, and electric imported German motor, low noise and large displacement of the motor to ensure long-term stability and reliability.

5. The appearance is beautiful, and it is used in conjunction with the soundproof window and dissolves into one with the window.

6. The electric air purification device can ensure the fresh air in the room after decoration; Electric ones are more energy-efficient, consuming only half a kilowatt-hour of electricity per day.

7. Easy to operate and maintain.

The principle of soundproof windows is to use the vacuum that cannot transmit sound to insulate sound, because there is no air between the two layers of glass of soundproof windows, so it can play a soundproof effect.

Advanced production equipment, advanced technical equipment, the use of soundproof materials, the use of screens, the use of some advanced technology, in order to achieve such an effect.

The air pressure resistance of the system doors and windows, the high-strength compressive strength profiles and tempered laminated glass are selected on the profiles and soundproof laminated glass, which are 3-4 times that of general windows, which can reduce noise very well. Consult the new standard doors and windows for details. The three-layer hollow tempered glass makes the home environment get a triple isolation guarantee, so that the heat transfer is slower, the sound insulation effect is stronger, and you can enjoy the time quietly and no longer worry about the electricity bill.

Benefits of using system windows and doors:

1. Block noise and keep the room quiet. The guarantee of sound insulation performance is not only the choice of broken bridge aluminum and seals, but also the choice of glass, so the commonly used glass for system doors and windows are insulating glass, and there is space between the insulating glass, filled with argon, and excellent heat and sound insulation performance is obtained.

2. Low heat conduction, warm in winter and cool in summer. The thermal conductivity of the middle air layer sealed by the double-layer insulating acoustic glass is much lower than that of ordinary glass, so the thermal insulation performance of the insulating glass is doubled, which can greatly reduce the power consumption of air-conditioned buildings.

3. Moisture and dust are not easy to enter. Sealing tape set isolation, drying, sealing trinity; The rubber band can be bent arbitrarily to make various shapes of insulating glass, with good sealing, moisture and dust are not easy to enter, which is the gospel of the house.

4. Transparent and bright, enjoy the beautiful scenery. Insulating glass is not easy to get cold in the glass on the indoor side and in an environment with high temperatures, so it is not easy to frost. Due to the internal sealing, there is a desiccant on the qualified aluminum alloy separator, which plays the role of absorbing moisture.

The three-layer stepped drainage of the new standard doors and windows is designed with an innovative stepped structure to scientifically improve the rainwater discharge, and the effective rainwater backflow phenomenon does not have to worry about the stormy weather. Triple sealing function, ring ring fastening, forming an integrated sealing technology, that is, 3S sealing patented technology.

The three-layer sealing strip design forms an effective elastic sealing wall through the automotive-grade foam co-extrusion rubber strip, which firmly isolates noise, rain, heat, etc., so that not a drop of rainwater has a chance to penetrate into the home.

A peaceful home life is important for everyone, but some people choose the lower floors for various reasons, which makes them vulnerable to noise. How to choose the doors and windows of low-rise residents to effectively isolate noise?

Seal the balcony

Now every household has a balcony, and the balcony of the low-rise residents can choose to seal it. To seal a balcony, you don't have to build it with cement, even if you seal it with glassIt can also have a good isolation effect on noise, and at the same time, it can also block dust, and it can also play a certain anti-theft effect

Broken bridge aluminum window

Broken bridge aluminum windows are one of the windowsIt is characterized by strong sound insulation, so low-rise users can choose broken bridge aluminum windows when installing windows. In addition, due to its good sealing, this kind of window not only has strong sound insulation, but also excellent waterproofing.

Sliding windows

Compared to the general type of windows,Sliding windows are more likely to provide a better sealTherefore, low-rise residents choose sliding windows to better block out noise.

Acoustic adhesive strips

We know that there is a layer of sealing strip on the edge of the window, and we can choose the best soundproof adhesive strip for this kind of sealing strip. Whether the adhesive strip is bad or not is related to whether it can block the noise out of the gap. At the same time, when the strip has been used for a certain number of years, or it has become yellow and hardIt should be replaced in time to avoid the aging of the adhesive strip, so that the sound insulation performance of the window is reduced.

Acoustic glass

Modern glass production technology is becoming more and more developed, and the styles of glass are also very rich, including soundproof glass. Residents with lower floorsYou can choose the best soundproof glass, such as vacuum glass or composite soundproof new glass.

If you want to isolate the noise from the doors and windows of low-rise residents, you can install silent cotton.

Doors and windows should be well insulated, and sliding windows and soundproof glass can be selected.

You can choose glass installation with good sound insulation, ask the decoration master to understand, and low-rise users can seal the balcony with glass.

To seal a balcony, you don't have to build it with cement, even if you seal it with glass

Just buy that kind of thick soundproof glass, or it will really make you noisy.

Seal the balcony and seal the gaps with a silent cotton.

Effectively isolating the noise, which means that you can't hear it, you can still bring it a little bit.

Solve window noise easily.

Dusting. Observe whether there is dust accumulation at the junction of the window pulley and the track, and if there is obvious dust, please use a brush to clean and remove dust.

Correction. Check whether the window pulley is deformed in conjunction with the track. If there is obvious deformation, you can use needle-nose Qiyun pliers to correct the mold.

Lubrication and rust removal. Observe whether the window pulley is visibly rusty at the junction with the track. If there is obvious rust, you can apply anti-rust oil to remove rust and then apply lubricating oil, and finally gently push and pull back and forth a few times to eliminate window noise.

Doors and windows need to be opened, compared with the walls are relatively light and thin, and there are sealing parts to form an overall sound insulation bottleneck. First of all, doors and windows account for 80% of glass, ordinary glass, insulating glass due to the penetration of sound waves and the sound wave anastomosis effect of ordinary insulating glass, resonance trough caused by the low efficiency of sound insulation, so insulating glass is not sound insulation or sound insulation effect is ignored, vacuum glass is not sound insulation. Generally speaking, the sound insulation of vacuum glass is not as good as that of insulating glass, and the sound insulation of normal insulating glass is about 10-12 decibels, while the sound insulation of ordinary plastic steel doors and windows is about 5-7 decibels.

Therefore, the first consideration of soundproof windows is to use suitable soundproof glass, followed by the use of soundproof profiles, and then to consider the sealing strip with good sealing effect, and the perfect unity of the three can make an ideal soundproof window.

Generally, the glass material of soundproof doors and windows is mostly made of transparent glass with a thickness of more than 5mm (while the glass of the general old-style aluminum windows is mostly 3mm thick glass), and the general design can usually accommodate the glass installed to 10mm thick, so it is recommended to use 5 8mm thick transparent glass in general, if there are special needs, consider (5mm+3mm) or (5mm+5mm) glued glass.

The above three points are the three key points to evaluate the effect of soundproof doors and windows.

Compared with ordinary doors and windows, the system doors and windows have better performance than ordinary doors and windows, such as sound insulation, heat insulation, warmth, air tightness, and water tightness. Especially in terms of noise reduction, it is more advantageous. I myself am very concerned about the noise of the living environment, so I use Guangzhou Olympun, such doors and windows are made of insulating glass structure of different thicknesses and thermal insulation bridge aluminum cavity structure, which can effectively reduce the resonance effect of sound waves, prevent the transmission of sound, and adults and children are comfortable to live in.

The system is completed and can reduce the noise in the house, because of the glass.

It can not be completely blocked, of course, energy-saving doors and windows are generally better sealed and insulated, and the sealing and thermal insulation are good, and its blocking effect on sound is good. But it can't be completely blocked. Some of the sound will still pass through the structure and penetrate to the other side.

After all, doors and windows themselves can also become a medium for sound transmission, but their sound impedance is relatively strong. It seems that there will be such phenomena in life, such as interrogation rooms, soundproof rooms, etc., and the sound inside and outside seem to be completely inaudible. It cannot be heard only because the sound intensity inside is not strong enough, the sound frequency penetration is weak, or it is masked by the ambient sound outside the soundproof room.

If you change to a loud enough sound, the low-frequency sound with strong penetration will also penetrate the sound insulation structure.

In order to completely block sound, it is necessary to ensure that there is no medium to transmit sound. That is, only in the vacuum state can sound not be transmitted. And the reality is that there is no absolute vacuum.

Energy-saving doors and windows and soundproof doors and windows are two completely different products, even if KOHO these brands of soundproof doors and windows can have two functions of sound insulation and energy saving, then sound insulation and energy saving are not the same kind of function that can be compared, and there is no saying whose doors and windows can completely block noise, completely blocking noise is unrealistic, he can only reduce the noise, to a certain extent, such as dev soundproof doors and windows The volume insulation can be reduced by more than 46 times, and this grid volume is still the sound insulation of the wall, and the sealing of various holes in the wall.

From a functional point of view, energy-saving doors and windows are used for thermal insulation. Blocking noise is the function of soundproof doors and windows. Energy-saving windows and doors to block out noise are unrealistic.

Doors and windows that can achieve energy-saving, sound insulation and fire-proof functions at the same time are the only KOHO functional doors and windows with such comprehensive capabilities. However, he did not emphasize all the functions of functional doors and windows, or did not highlight a certain function, but highlighted the comprehensive function, saying that his sound insulation performance and fire prevention function were also OK, such a comprehensive performance. The ranking is not an advantage, but it is not bad, and you can get a high score together.
