Installing ceramic or porcelain tile is both an art and a science. Tile installers must know the composition of the tiles as well as how to lay them in place attractively. Besides the normal costs of labor and materials, a tile project's costs vary by the type of sub-flooring to be used as a foundation for the tile.
Three things can cause an EMI problem: A signal source creates some kind of noise, there is a transmission path for the noise, and/or there is a receiver sensitive enough to be distorted by the noise, as shown in Figure 1.
Installing insulation is one way. Limiting the transmission of sound from one area to another requires a material that encloses the source of the noise, forming a barrier between the source and the adjacent areas. This is exactly how insulation works! There are two types of noises: airborne and impact.
