Resumen
This paper presents and analyses the results of acoustic measurements of the airborne sound insulation and impact noise between overlapping rooms with thin (12-14 cm), single direction overlaid slabs, built up to the early 1960s in rooms over 250 m3. The experimental values for the acoustic parameters are as follows: weighted apparent sound reduction index Rw and weighted normalized impact sound pressure level Ln,w have been compared with the one predicted by the estimations in the calculation models in the standards UNE EN 12354 parts 1, 2:2000. As a conclusion, an experimental reciprocity relation was obtained for the addition of the values of the apparent sound reduction index and the normalized impact sound pressure level.
