there are many indicators to measure a comfortable home environment. Noise is undoubtedly one of the hard indicators. According to international standards, in downtown areas, outdoor noise cannot exceed 55 dB during the day and 45 dB at night; In general residential areas, it cannot exceed 45 decibels during the day and 35 decibels at night. If people are exposed to noise for a long time, it will produce adverse reactions and may induce "noise disease". In addition to damaging hearing, noise will also affect other systems of the body and bring some physiological symptoms, such as insomnia, neurasthenia, autonomic nerve dysfunction, unstable blood pressure, etc. Generally, people affected by noise will have symptoms such as irritability, fatigue, difficulty in concentrating and slow response

in the noisy city, to make home a quiet harbor, you need a "scientific plan" to create a quiet home

as one of the top ten brands of aluminum alloy doors and windows in China - Guangdong? Yacai doors and windows is committed to creating high-quality silent doors and windows for the majority of elite classes in the selection of profiles, production technology, glass processing, as well as the technical training of front-line workers

a sound experiment was done through the on-site NC mute experience box. Put the maximum volume music played by the mobile phone into the mute experience box, and you can hardly hear the sound of music outside

sub material? Silent doors and windows have made great improvements in sealing and sound insulation performance. In addition to increasing the thickness of insulating glass (up to 5+18a+5), the transmission of sound waves is blocked to the greatest extent. In terms of the air tightness of door and window structures, high-quality rubber strips are used for seamless sealing and splicing, which greatly improves the sealing performance of aluminum alloy doors and windows

from the test above, we can see that the sound decibel in the mute experience box is 114dB, while the sound decibel outside is 75db. It can be concluded that the effective sound insulation decibel of zunshang doors and windows is 39db. After scientific certification, 35 to 50dB is the most suitable environment for people to rest and sleep, and the noise index of ordinary families is usually about 70 dB, which is easy to affect people's sleep. But if you are in a room equipped with zunshang doors and windows, Subtracting 39db of effective sound insulation of zunshang doors and windows from 70dB, the result is 31dB, which is even lower than the lowest decibel suitable for people's comfortable sleep, truly realizing one window and two worlds

create a comfortable and quiet environment, reject noise, sub material? Mute doors and windows can be done. As the leader of the new era of aluminum alloy doors and windows in China, Guangdong Yacai opens a new experience of home life quality with perfect silent doors and windows
