Methods of sound insulation in wood structures differ from those in solid structures. Wood structures built to be fire-safe often have very good sound-insulation properties as they are.
In order to achieve good air-borne sound insulation, partition wall and intermediate floor structures are built in layers, and the layers are separated from each other to prevent the sound being conducted through the structure. In order to improve footstep sound insulation on floors, material is added to the floors, which reduces structural vibration. From a point of view of good sound insulation, it is important for the structures and their joints and perforations to be tight. Structural sound insulation is only as good as its weakest link.
With wood structures, you can achieve excellent sound insulation and so meet demanding sound insulation requirements.
