Extension of the Simplified Method for Estimating Sound Insulation between Rooms in Buildings
Original language description
The new simplified method for estimating the flanking airborne and impact sound transmission between rooms in residential buildings was published in 2014. It is based on the theoretical models described in parts 1 and 2 of the technical standards ČSN EN ISO 12354. This method enables quick estimation of in situ sound insulation in buildings with common building elements. Recent activities have extended its possible use to include walls and floors with acoustic linings (both on separating or flanking elements). This paper describes the principle of extension and provides examples of its application to typical building situations. It is shown that the resulting theoretical airborne or impact sound insulation improvement by additional lining depends dramatically on the degree of flanking transmission in the original situation. This finding would provide particularly important information for an accurate design when the laboratory data of improvement are used.
