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 R´w and weighted normalized impact sound pressure level L´n,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.
