The sound insulation of materials need to be measured in the reverberation room, the area of panel structure is 10m2 normally [1].
In other words, the Mass law is that the sound insulation will increase 6dB theoretically if the sound frequencies or the surface density of materials doubled.

The sound insulation wall is built by the stone material demolition of the building, making full use of the abandoned building materials to save materials.
New wall materials are adopted, using slag and fly ash industrial waste, to protect land resources and reduce the pollution to the environment.

Figure 1 – Etched micrographs of the tested materials over the cross section of the bar material Except for X5CrNi18-10, the materials show a homogeneous structure over the entire cross section.
For the other two materials, the bar stock has a diameter of 20 mm.
The sample geometries and test materials have been described in section 2.
