The difference between the 4th generation mute and 5th generation mute of Tata Wood Door is that the soundproof strip is more sealed. According to relevant public information, Zong Ruiyuan, chairman of Tata Wood Door, revealed the core principle of the fifth-generation mute door, saying that Tata Wood Door added sound insulation strips on the basis of the fourth-generation mute technology, which increased the sound propagation path, thus achieving the effect of reducing noise and making the living space quieter.
