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.

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-Induced Hearing Loss. Noise-Induced Hearing Loss (NIHL) occurs when loud noise damages the working of the inner ear and causes hearing loss. It can be the result of a one-time exposure to an intense impulse sound, such as an explosion, or by continuous exposure to loud sounds over an extended period of time. Roughly 20% of adults in the US, about 48 million people, report some degree of hearing loss. At age 65, 1 out of 3 people have hearing loss.
