Recently, many netizens asked, how to reduce noise pollution in cities with home decoration? Now choosing some effective soundproof doors and windows materials to "arm your own house" has become a concern for many residents.

Sound insulation material types
There are roughly three types of sound insulation materials on the market: hollow glass is composed of two or more layers of glass, and the two or more pieces of glass are bonded with aluminum alloy frames or rubber strips with high-strength composite adhesives around it, leaving space between the sealing glass, and filling it with argon, that is, inert gas, to obtain excellent thermal insulation performance. Due to the poor heat transfer performance of air or gas stored in the glass, it produces superior sound insulation.
laminated glass refers to PVB intermediate film sandwiched between two or more glasses. The PVB intermediate film can reduce the amount of noise penetrating the glass, reduce noise decibels, and achieve sound insulation effect. For example, laminated glass made of SAflexPVB plastic intermediate film can effectively block common anastomotic noise of 1000 to 2000 Hz.
sound-absorbing decorative panel is a new type of building material, with excellent sound-absorbing performance and flame retardant and fire-resistant effects. Generally, there are many colors and patterns for decorative cloth to choose from. Some products can also be processed into various shapes of sound absorbing bodies according to design requirements.

Aluminum Alloy Doors and Windows Features
The sound insulation performance of aluminum alloy doors and windows depends on the adhesion between the two windows and between the window frames. The push-opening of the window depends on the adhesion between the window and the frame after closing. Aluminum alloy doors and windows are generally sealed with ethylene propylene glue strips. Unlike the "hard-hard" of ordinary aluminum alloy windows, the sound insulation effect is more obvious. "
Xinshengyuan doors and windows have many types. In addition to the traditional inner and outer casement, push-pull and folding, there are also inner casement upper hanging doors and windows, push-pull upper hanging doors and windows, push-pull upper hanging doors and windows, and push-pull lower hanging doors and windows. The common aluminum alloy doors and windows on the market are mostly porcelain black, but colored profiles also appear.
Aluminum alloy doors and windows have good sealing performance, ensuring sound insulation effect, but also bringing the weakness of insufficient air circulation. In response to this situation, a ventilator used when closing windows has been developed, which does not affect sound insulation, but also ensures the exchange of indoor and outdoor air. The ventilator can be installed in the window There is no space between the window line.

Generally people think that the sound insulation effect of aluminum alloy doors and windows is not good, but in fact, the new aluminum alloy doors and windows have made great improvements in the sealing and sound insulation performance. The sound insulation performance of windows mainly lies in the sound insulation effect of glass that accounts for about 80% of the area, and secondly lies in the sealing performance of doors and windows.
Some aluminum alloy doors and windows products on the market now use different glass combination structures to enhance the sound insulation effect. In terms of airtightness of doors and windows, high-quality glue strips and plastic sealing are used. The use of parts also greatly solves the problem of poor sealing performance of aluminum alloy doors and windows.

Noise exceeds 50 decibels to affect sleep and rest
Noise can be expressed as sound level, unit is decibels (dB). Noise level between 30 and 40 decibels is a relatively quiet and normal environment; more than 50 decibels will affect sleep and rest; more than 70 decibels will interfere with conversation, causing distraction and inattention; long-term work or living noise above 90 decibels The sound environment will seriously affect hearing and lead to the occurrence of other diseases such as cardiac blood vessels.
The most direct harm of noise to the human body is hearing damage. When people enter a strong noise environment, they will feel uncomfortable in both ears and even feel headaches. Noise will reduce labor productivity by 10% to 50%, and as the noise increases, the error rate increases. It causes people to respond slowly, be prone to fatigue, work efficiency decreases, and error rate increases. Noise can induce a variety of diseases. Due to the effect of noise, neurasthenia symptoms such as headache, brain swelling, tinnitus , insomnia, general fatigue and memory loss.

At the same time, noise will also produce psychological effects. Under high frequency noise, most people are anxious and prone to excitement. Living in a high-noise environment for a long time can easily make people feel irritable and depressed, affecting their work efficiency. Choosing a good aluminum alloy doors and windows can bring a healthy and comfortable living environment, while also providing energy-saving and safe effects.
