Dry sand as a specialized layer to improve the acoustic insulation between rooms one above another
Keywords:Floor constructions, sound insulation, floating floor, sand, restoration
This work presents and analyses the experimental field results of the sound insulation from airborne and impact noise of the horizontal separating elements commonly used in the past, in which a uniform layer of sand was placed on top of the floor construction to serve as a base for the ceramic tiling. The results of the acoustic measurements show that when there is an intermediate layer of sand in the horizontal separating element between rooms, the sound insulation is greater than would be obtained with other construction systems with equal mass per unit area, where the floor is joined rigidly to the floor construction. The effect on the sound insulation between the rooms produced by this layer of sand placed between the floor construction and the tiling is that of a cushioning layer, and demonstrates that this type of structure acts as a floating floor.
