Measurements in the new Salle Pleyel

Room acoustics measurements have been conducted in the newly renovated Salle Pleyel, in Paris, in order to characterize changes in the acoustics of the hall since its reopening in September 2006. These measurements were made with a simple setup, and data were treated with two different analysis packages: the Room Acoustics Toolbox (RAT) and a renovated version of MIDAS, created in the late 1980's, by Polack, Marshall and Dodd [1]. Both packages run under MatLab The aim of this paper is on the one hand, to update the public database of acoustic indices of the Salle Pleyel, comparing them with those found in the past by previous studies and, on the other hand, to compare results provided by the two codes. The differences will be presented as well as different parameters settings. The paper concludes with a short presentation of the features of the new MIDAS package, destined to be made available to the public.
