Abstract

This work presents and analyses the results of the acoustic measurements of insulation from airborne noise and impact noise in solid reinforced concrete slabs designed by Eduardo Torroja Miret and manufactured in the first half of the 1930s in the School of Architecture of the UPM Polytechnic University in Madrid, located in the Ciudad Universitaria in Madrid. The experimental values for the acoustic parameters: weighted apparent sound reduction index R’w and weighted normalised impact sound pressure level L’n,w are closely related with those predicted by the estimations in the calculation models in the European standards EN 12354 parts 1, 2:2000. An experimental reciprocity relation was obtained for the sum of the values of the apparent sound reduction index and the normalised impact sound pressure level.
