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.
In rare cases, tumours can also cause conductive hearing loss â they block sound from getting into the inner ear. Birth defects and diseases passed on by genes can do this, too. Genetics is one cause of sensorineural hearing loss. Half of all cases of profound deafness in children have a genetic source.
