It’s the isolation of sound vibrations. Insulation measures are mainly carried out by structural interventions in the office building. The term refers to the restriction of sound propagation through room boundaries. Insulation is therefore a measure for the acoustic separation of rooms against unwanted noise from neighbouring rooms or from the outside. It’s a basic parameter of building acoustics.
A distinction is made between airborne sound insulation and footfall sound insulation. Airborne sound is caused by sound sources in the room that have no direct connection with the room boundaries, e.g. people talking. Impact sound, on the other hand, is caused by structure-borne sound (footsteps, knocks), which in turn stimulates walls or ceilings to emit airborne sound. Insulation against airborne and impact sound is subject to the requirements of law for buildings.
