Acoplamiento acústico de sala de ensayo coral

This paper suggests modifications to be considered in order to improve the acoustic comfort of a choir rehearsal room. In addition, these modifications contemplate the acoustic coupling with a dressing room located next to it. Reverberation time measurements (EDT, T20 and T30) were carried out in situ and from the results obtained, the behavior of the room was simulated in EASE and COMSOL. In this way, the results obtained from the proposed modifications were also evaluated, achieving a reverberation time of 1.02 s for the choir rehearsal room, and 0.46 s for the dressing room. The results presented in this work also includes absorption and scattering coefficients of every surface material and SPL mapping of the rooms.
