• Resumen

  • The Room of Rehearsal of Orchestra of the Great Theater of the Liceu, inaugurated together with t.he whole new theater, in October of 1999, allowed to job a medium orchestra but it was not appropriated for a great orchestra, due that the dimensions neither volume had at least a value appropriated. The urban planning conditions of Barcelona had limited to all workspaces rehearsal rooms and other spaces in Theatre built. This initial deficiency has been corrected in many aspects in the Rehearsal Room of orchestra with a new acoustic planning conception. With this new acoustic planning we developed by a 3D-Grid diffractor designed by us, we have obtained an increase of Reverberation Time in the room and moreover we got to avoid that different instruments were mixed excessively, avoiding the confusion and trouble among the musicians.
