The ground sound-insulated

الوصف

The grounds sound-insulated & weaken the vibration cushion is made from high-density rubber which is *0mm and polyethylene, which is made through a Nan technology. 1. Product characteristic: It has very good effect to block the sound, which is impact noise that is during the whole frequency range. It has the most effective isolation hit noise and the air dissemination noise. The product is a kind of high-density material; its perforation rate and the hole diameter are all through special designed. The product can achieve isolation sound, prevention vibration, the waterproofing, prevent mildew and is suitable to each kind of moist environments. The product is a kind of green environmental protection product, and it can be used for more than *0 ***** is very convenient to install, you can only use cutting tools to cut but not use the other tools. 2. Product soundproofing principles: 1. Isolation impact noise. Through the froth elasticity to make the floor form the fluctuation structure and using the tiny holes to absorb the noise, so to achieve reduces the impact noise. ***** air noise. Through the resonates the effect of nanometer froth cavity body to change the sound transmission the frequency, and reduce the reflection number of times, to achieve isolation air sound.
