随着人民生活水平的日益提高,住宅的隔声已成为人们比较关注的问题。传统结构中住宅分户墙均为24厘米厚砖墙,空气隔声没有什么问题。各种砌块墙由于重量及厚度改变不大,隔声效果基本接近砖墙。一般不会低于Ⅱ级标准。目前问题最多的是出在轻质隔墙上。有人总是把隔热和隔声混淆起来,想做成空心的板、块或搞一些新的轻型隔声材料来改进隔声,结果都很失望。因为声音在空气中传播时遇上墙,就要引起墙的振动。因墙的振动会向邻室辐射声音。如果要求隔声好,只有希望墙的振动小,增加重量是有效的办法。但重量增
With the ever-increasing living standards of the people, the sound insulation of houses has become a problem that people are more concerned about. In the traditional structure, the residential separation walls are all 24 cm thick brick walls, and there is no problem with air sound insulation. Various block walls do not change much due to their weight and thickness, and the sound insulation effect is almost similar to that of a brick wall. Generally not lower than the level II standard. The current problem is the most out of the light partition wall. Some people always confuse insulation and sound insulation. They want to make hollow boards, blocks, or new lightweight sound insulation materials to improve sound insulation. The results are disappointing. Because the sound meets the wall when it travels in the air, it will cause the wall to vibrate. Because of the vibration of the wall, it will radiate sound to the neighboring room. If sound insulation is required, only the vibration of the wall is desired. Increasing the weight is an effective way. But with an increase in weight
