Acoustic bridge is the place in a building envelope where sound penetrates more easily than through the rest of the structure. Sound reduces the sound insulation of walls, ceilings or the joints between them.
It usually arises at the junction of different materials, at structural connection points and with inadequate filling of the insulation space. It also occurs where load-bearing elements create a rigid vibration transmission path. Typical sources of sound bridges include discontinuities in insulation, lack of flexible shims under timber elements, cladding that is too rigidly fixed and faulty wall-to-ceiling joints.
Elimination of acoustic bridges requires appropriate selection of damping materials, This is particularly important for all types of construction, including the construction of new buildings. This is particularly important for achieving acoustic comfort in all types of construction, including for prefabricated construction.
