Impact sound transmission loss is the ability of structure to absorb impact noise, which is formed by mechanical impulses (steps, falls). The impact noise is then spread to the elements connected to the floor structure, such as the ceiling and surrounding wall. Dynamic stiffness is one of the important parameters that affect the sound insulation of ceiling structures with floating floors. The article deals with the optimal design of acoustic insulation to the floor composition, combining different materials of various thicknesses with various characteristic properties. |
