Analysis of the acoustic performance of slabs regarding airborne sound and impact, at the university city of madrid

Abstract

The existence of a general model of acoustic prediction in the Spanish legislation is widely known. It has been based on the simplified models previously defined in the EN 12354 standard. In this work, different types of slabs in overlapping enclosures, built between 1927 and 2003 in the Ciudad Universitaria of Madrid, and with volumes larger than 250 m3 are compared. After testing them, the accuracy of the predictions were checked obtaining differences in weighted standardized levels and evidencing a bias in the predictions when standardized impact noise pressure levels were obtained.
