Decides the laminated glass to have the sound insulation effect the factor
First, the laminated glass of the noise volume is subject to the law of quality, namely: surface density (material density and thickness of the product) to determine the size of the overall sound insulation; understanding of laminated glass are aware, laminated glass is generally two glass Film composition, thickness is not large, glass density, and thus laminated glass surface density, and its sound insulation performance is ideal.
Second, laminated glass there is an acoustic performance of the match effect. The purpose of the noise reduction and vibration control is to find the frequency of the sound wave of the anastomotic effect is not in the frequency range of noise reduction. The coincidence effect of the laminated glass is about 3000Hz, far away from the traffic noise in the middle and low frequency, is the most ideal busy traffic The use of soundproof glass.
Third, laminated glass The middle of the film is equivalent to a damping layer, can effectively suppress the glass vibration, thereby enhancing the glass's sound insulation performance.
Fourth, clip film damping performance is better, laminated glass, the overall sound insulation performance is better (1 to 3 dB), especially for the low-frequency noise performance.
As a result, laminated glass because of its own structure and material, the noise performance is very good, because of its excellent material, durable use, is the best material for soundproof windows.
