The acoustical conditions of rehearsal rooms are of great importance for orchestra training. In those specifics spaces, both performance and working acoustical conditions are expected, but there is no guidance of operations for designing such a space. La Sirène de Paris is a cultural association whose principal activity is music. Its residence is a trapezoidal rehearsal room whose volume is about 1150 m3 situated in Paris 14th district. This paper presents the care taken by acoustical consultant IMPEDANCE SAS in the rebuilding project and the relocation of the association in the building infrastructure. The most attention is paid to the correlation of user’s perception of the actual acoustical characteristics of the rehearsal room by comparing a subjective study with objectives physical measurements. The sound exposures of orchestra players are taken into consideration. A study of other rehearsal room indicated by the users as being good for orchestra practice is used. Aiming for the reproduction and improvement of acoustical conditions of training for the orchestra musicians in the new rehearsal room, results show the correlations between perceptual and objective measurements and the relation between requested acoustical characteristics and design issues.
