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.
Loud noise exposure can also cause tinnitusâa ringing, buzzing, or roaring in the ears or head. Tinnitus may subside over time, but can sometimes continue constantly or occasionally throughout a personâs life. Hearing loss and tinnitus can occur in one or both ears.
