Many people will make a big fuss on windows when decorating interiors, in order to give their indoor space an excellent sound insulation effect, and many people will choose windows with excellent sound insulation effect. However, my house has installed windows worth tens of thousands of yuan, so why can't Isolate the noise from the road? Let's take you to learn more about it.
htmlWhy is there no noise in the road for tens of thousands of yuan in windows,At present, the noise in the community can be mainly divided into square dance sounds inside the community and car whistles on the road. The sound of square dancing inside the community is usually high-frequency noise and can be effectively isolated through the window. The sound of cars on the road is low-frequency noise , which is relatively difficult to isolate.
Noise on the road will be affected by the occlusion and the distance of the sound source. Therefore, different floors are also affected by road noise. In communities near the road, the middle floors are most severely affected by the noise from the road. If it is a community covered by buildings or green plants, the top floor will be most affected by road noise, while the bottom floor will be relatively unaffected by road noise.
Which window glass has good sound insulation effect
1, vacuum glass
Many people believe that vacuum glass has good sound insulation effect because the sound cannot be spread without air, but. Because there are many tiny metal support objects in the vacuum glass, noise can still be transmitted through the metal support objects. At the same time, if there is air leakage in the vacuum glass, the effect will be greatly reduced. We need to be cautious when purchasing.
2, hollow glass
hollow glass has excellent sound insulation and heat insulation effects, but this kind of glass can only isolate high-frequency noise such as radio, vocals, speakers, etc. It has poor insulation effect for those mid- and low-frequency noises from road cars. We need to choose according to our own living environment.
3, laminated glass
laminated is to clamp a piece of PVB film between two pieces of glass. This film can hinder and buffer the vibration of the glass and block the propagation of noise. It has excellent effect of isolating medium and low frequency noise, and also has a certain effect of isolating high frequency noise.
To sum up, the sound insulation effect of these three windows is hollow laminated glass hollow glass vacuum glass.
