Abstract

This chapter deals with the sound transmission between rooms of a building (or from the outside into the building respectively). This subject of practical importance concerns the noise control of indoor rooms with respect to traffic noise and residential noise. Noise, penetrating a room from the exterior, can have two possible reasons:
  1. 1.

    Walls are directly excited by forces acting on walls or ceilings by walking on a floor or operating a machine in the building The exciting force results in vibrations of the structures in the building and structure-borne sound develops which is transmitted to other floors further away. The vibrating structures excite the surrounding air and radiate sound. This sound development mechanism can be summarised by the terms ‘force — structure-borne sound — airborne sound’ (Fig. 8.1).

     
  2. 2.

    The airborne sound in a room, like speech or the operation of consumer electronic devices or machinery, also represents an exciting force with respect to the surrounding walls and ceilings, which represents a spatially distributed force and not a point force (as above) this time. Vibrations are also generated in the structures. The transfer path can be described by ‘airborne sound — structure-borne sound — airborne sound’ (Fig. 8.1).
