On the issue of housing ceiling, mainly soundproof, understand into the
According to the situation you describe, even if you do a ceiling noise, or to wear earplugs to sleep. Unless you want to lower the height of 40cm or more, while the cost is still very high.
Upstairs do not agree with the method, of course, is the noise ceiling, and this noise has three points need attention:
1, the main function of the ceiling is not sound, but the sound absorption;
2, whether it can save more layers of high space, the use of flexible ceiling;
3, choose a thin sound of some of the material, of course, this thin, the need for the heavier the better material.
The price should be in the general ceiling of the two awards price around.
The above is the country for the upstairs inside the house downstairs provisions, in fact, the most effective treatment of your problem is to go upstairs that households to do "floor vibration pad" project, of course, this will be more trouble to do Upstairs with the same do not agree, or a question, and agreed, but also need to live outside the elderly to live a few days Caixing, or else the work is not good! Inexpensive, should be more than the cost of some of the ceiling. Advantages: and cheap and good results. Disadvantages: more difficult to communicate with the leadership, of course, good leadership is not the same.
Floor noise standards include two parts: air sound insulation standards and impact sound insulation standards.
Air sound insulation is the ability of the floor to isolate the air from the sound, taking into account the different frequencies of the sound, the use of weighted sound insulation (dBA); percussion is the upper residential objects hit the floor, so that the floor vibration through the structure passed to the lower residential space The Impact sound insulation is the floor to pass the standard impact sound size, taking into account the different frequencies of the sound, the use of weighted standard impact sound pressure level (dBA). It can be understood that the higher the standard sound of the sound insulation sound of the floor, the better the air sound insulation performance; the smaller the standard data of the impact sound of the floor, the better the sound insulation performance.
Civil building noise design code GBJ118-88 on the building of the building sound insulation standards have been provided, the specification applies to the country's new towns, expansion, alteration of residential, schools, hospitals and hotels and other four types of buildings in the main building Sound insulation noise reduction design, according to the use of the building requirements, sub-premium, one, two, three, a total of four grades, including the highest premium, three lowest
