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.
Noise related hearing loss. Loud noises can damage the cilia (small hairs) in the inner ear which regulate the flow of sound waves. Severe damage to cilia is permanent but even a short period of excessive noise can result in tinnitus or hearing loss for a period of time.
