Theoretically, the main factors influencing the sound insulation of the gypsum board wall are as follows: 1) the law of quality: there is a common law for the insulation of the partition, that is, the heavier the material (the greater the surface density) the better the sound insulation. For a single layer of dense uniform wall, surface density for each doubled, the sound insulation in the theoretical increase of 6dB, this law is the law of quality. For the double layer of gypsum board wall, the law of quality plays an important role, that is, to increase the number of layers or thickness of the board can be improved sound insulation. As the keel double wall system sound vibration form is very complex, so the embodiment of the law of quality than the simple single-wall complex. 2) Resonant frequency: any partition wall there is an inherent resonance frequency, when the sound wave frequency and wall resonance frequency, the wall as a whole resonate, the frequency of the sound insulation will be greatly reduced.

Install the edge along the top keel Along the ground, along the top keel in place, with the nail fixed, shot nail from the 900mm, the location of the nail should avoid the laying of the tube area. 4. Install the vertical keel According to the determined vertical keel spacing, along the ground, along the top keel on the line drawing line. The vertical keel is arranged by the end of the wall. When the doors and windows are provided with windows and doors, they should be arranged from one side or both sides of the door window. When the last keel from the wall of the size is greater than the provisions of the keel spacing, you must add a keel.
