Abstract: In this article the sound insulation index Rw of partitions is analysed.Sound partitions are built from various materials: bricks, ceramsite blocks, clay blocks, which differ in their composition, structure, and mass. Walls from the mentioned materials were constructed in buildings that were under examination. Sound insulation index‘es of the partitions were determined by measuring the insulation of sound under natural conditions, in the buildings where the partitions were constructed. Sound insulation index Rw, were also estimated using the law of weight and international standart LST EN ISO 12354 – 1. Experiments were carried out in newly constructed buildings and in a sound reduction chamber that was constructed in Vilnius Gediminas technical university. The sample under examination was set in the partition between sound transmitting and sound recieving rooms, which were isolated from surroundings. The calculated and measured results were compared and the reasons of mismatches were studied.
