The Present Position on Sound Insulation in Buildings

A sound source in a room usually produces a diffuse (i.e. non-directional) sound field. The sound pressure level of this field depends on the energy emitted by the source and the amount of absorption by the surfaces of the room. Most of this absorbed energy is lost as heat but a small part is transmitted through the walls or floor and radiated into adjoining rooms causing another diffuse sound field. Ihsically it is the difference between these two sound ficlds which is the airborne sound insulation of a wall or floor. H. J. Purkis
