Sound Insulation (or Noiselessness)

According to modern building concepts, a floor shall neither create noise while used nor should transmit noise, particularly in a vertical direction. In that case of ground or basement floors, the sound vibrations are damped out because of the contact along with the mass of the earth. Therefore, it is more significant a factor for upper floors, where they are supposed to act as horizontal barriers for the passage of sound in vertical direction. Therefore, the flooring material should probably be such that it either generates no noise or less noise when travelled over, especially for buildings like as libraries, hospitals, colleges, universities, theatres, etc. Cork tiles and rubber floorings give excellent sound insulation properties while the floors of wood, linoleum, asphalt, etc. also serve these reasons satisfactorily.
