Abstract :
Separating element junctions make a dual contribution in the calculations of sound insulation according to EN 12354 standards. Junction types and vibration reduction index values determine the amount of the vibration energy which will be transmitted from the separating to the flanking elements, and therefore the flanking transmission between the source and the receiving room. On the other hand, vibration reduction index values influence the structural reverberation time of the element, by quantifying energy losses at its junctions. The aim of this work is to quantify the influence of the separating element junction types on the calculated value of airborne and impact sound insulation.
