In a prosperous city, noise is everywhere, affecting our quality of life. Want a quiet sky? Then we should know how to choose Wuxi sound insulation window 。 Remember the following key Word, let you away from the noise, enjoy a quiet life.
Key word 1: damping mute Glass 。 Damping silent glass is an effective way to solve the medium and low frequency noise. The common noises in life, such as the roar of the bus engine and the tire noise, belong to the middle and low frequency noise. The damping mute layer can block and buffer the vibration of the glass, so as to achieve the effect of noise reduction. The isolation effect of this glass is very good, which can effectively reduce the noise of 39 to 41 decibels.
Keyword 2: Hollow glass 。 Insulating glass is the main glass noise reduction scheme to reduce medium and high frequency noise. By increasing the number of glass pieces, the vibration frequency of glass with the same thickness will be reduced. Taking the common double wave one cavity double layer central control glass as an example, the noise value can be effectively reduced by 34 to 35 decibels. In theory, the three-layer wind glass with three waves and two cavities can effectively reduce the noise value of about 35 to 36 decibels. However, the sound insulation effect of an additional layer of wind glass has not been significantly improved.
Key word 3: Plastic steel window 。 The main material of plastic steel window is PVC, and steel lining is put into the profile cavity to increase strength. The resonance frequency of plastic steel PVC material is low, which is the lowest in door and window materials. Compared with the plastic steel material, the material of bridge cutoff aluminum doors and windows is slightly inferior. Because its resonance frequency sound speed is about 6305 seconds.
Key word 4: vacuum glass. A vacuum glass is a vacuum state between the air layers of two vacuum glasses. However, because soundproof windows belong to personalized customized products, and the size, specification and size of each glass are different, there is almost nothing that can be used for vacuum processing of household glass. Even if there is noise reduction frequency, it is not as effective as multi-layer laminated glass. Ordinary consumers really don't need to spend more money, and they can't solve the problem.
Sound insulation misunderstanding: according to the national standard G314332015 document, windows with sound insulation of more than 35 decibels can be called sound insulation doors and windows, which is only the level 4 standard in the whole sound insulation performance level. The lowest level is six, which is more than 45 decibels. This is the lowest level in the current national standard. In addition, the general public often has two misconceptions about the sound insulation performance of doors and windows. First, it is not necessary to buy 35 dB sound insulation doors and windows to effectively block 35 dB outdoor noise; 2、 The use of 35 dB sound insulation doors and windows does not mean that the indoor noise will not exceed 35 dB. Because there is a big difference between the testing conditions of sound insulation performance of doors and windows and the outdoor conditions during the actual use of doors and windows, the sound insulation performance of doors and windows can only be used as a reference.
In a word, the selection of Wuxi soundproof window should consider various factors, including glass type, window frame material, product material, etc. In the process of selection, we should make reasonable choices based on our actual needs and environmental conditions. Only in this way can we create a quiet and comfortable living space for ourselves.
