DOI: 10.7764/RDLC.17.1.38Carolina Coronado Theatre was inaugurated in 1916. Its original design resembles a classical opera theatre, having a traditional horseshoe form, used throughout 19th century. Before the renovation its volume-number of seats ratio and its reverberation time with audience, were far away from some recommended values. Its renovation was done respecting faithfully the original appearance of the hall, without changes in the raised stage, seating area or walls and only including a new concept of acoustic dynamic shell based in diffusers, above the stage, that can create different acoustical ambiences. This acoustic configuration was slightly helped by covering lateral walls with acoustic panels. The results were obtained from the simulations in the software ODEON and “in situ” measurements.
