[China Glass Network] 1. If the environment around you is close to the main road, highway, viaduct, airport customers, because this kind of environmental noise is relatively large, the noise is estimated to be more than 78 decibels. In such an environment, there are generally two solutions that can reduce them to less than 40 decibels: one is to install a soundproof layer at least next to the original door and window, at least a vacuum soundproof door and window, the original door and window to the outside noise It is no problem to reduce the noise to 40 decibels by adding a vacuum soundproof window with a sound insulation of 38 decibels. The other is that if the customer suspects that the two windows are troublesome, then the original doors and windows are removed, and the composite vacuum soundproof doors and windows are replaced. The sound insulation of the composite vacuum soundproof doors and windows is above 44 decibels, and the above noises can be controlled at 40. Below the decibel.
2. If the environment around you is close to the general road, not the main road, highway, viaduct, airport, etc., the noise in this case is generally around 72 decibels. In this case, the noise control is required to be below 40 decibels. There are three options: the former is to install a soundproof layer at least beside the original door and window, and at least the soundproof windows and doors of the insulating glass. The noise is reduced by 30 decibels with insulating glass doors and windows, and the noise can be controlled below 40 decibels. The second is to remove the original doors and windows, plus our laminated soundproof doors and windows, the insulation of the rubberized soundproof doors and windows is more than 35 decibels, so that the noise can be controlled below 40 decibels. Thirdly, if the customer has requirements for the insulation of the sound-insulating glass to block the ultraviolet rays, vacuum-insulated doors and windows can be installed. The sound insulation of vacuum soundproof doors and windows is more than 38 decibels, which can achieve the effect. The vacuum-visible glass has a general visible light transmittance of 68%~82% and a reflectivity of 13%~25%, which can not only reduce the glare, but also prevent it. Fading and aging of interior items.
3. If your environment is not close to the road, it is just the noise that comes from other people in life, such as talking, selling, impacting by objects, air-conditioning mains, etc., like this type of high and low frequency around 68 decibels. There are two solutions to noise: one is to install a vacuum soundproof door and window with a sound insulation of about 38 decibels, and the other is to change the windows and doors, and replace the original windows with the composite insulating glass doors and windows. Both methods can guarantee that such noise will be cut off, and the sound of the outside will not be heard after closing the doors and windows during rest.
4. If your environment is surrounded by construction sites or other production workshops, such noise and noise levels are around 81 decibels. The high-frequency noise content of such noise is relatively large, and the noise is controlled to be below 40 decibels in close proximity. There are also two methods: one is to install a composite hollow glass soundproof door and window, and the composite insulating glass soundproof door and window is a soundproof door and window mainly for high frequency noise, and the sound insulation is above 42 decibels. Another method is to change the door and window, remove the original door and window, and replace the high-frequency noise and low-frequency noise to block the composite insulating glass door and window with a sound insulation of 44 decibels or more.
