During planning, the new materials and component structures are to be assessed with regard to sound insulation to adjacent rooms and room acoustics (floor coverings, wall structures, suspended ceilings, doors, etc.).

With regard to sound insulation, the planning for the building services and installations should be accompanied. Wherever possible, concepts for remedying existing deficiencies in the area of sound insulation are to be worked out (impact sound, sound transmission between offices and adjacent areas).
