Acoustical measurements in 10 atria

This report presents the measurement results of acoustical tests in 10 different atrium spaces. These measurements were made as part of the acoustical component of a multidisciplinary project to study the indoor environment of atrium spaces attached to office buildings. The acoustical component included the measurements reported here as well as computer simulation studies to be reported elsewhere. The main purpose of this report is to present a summary of the measurement results to characterize typical acousticalconditions in a wide variety of atrium spaces. Detailed analyses of these results will be left to future publications.
