To conclude, it should merely be indicated that our positive general evaluation of the results obtained from the work on the Carolina Coronado Theatre, which can be classed as good or even excellent, has been confirmed by the favourable view of actors, musicians and the public in the months since the work was carried out.
From the DXF file we obtained a final model faces and corners. Some different simulations were carried out, all of them using the same basic parameters number of rays, length arquiteectonica impulse response, number and position of receivers, etc. Acoustic Science Technology26 All the simulations used were carried out in the most unfavourable situation: London, Applied Science Publishers.
The incorporation of diffuser elements in the acoustic shell gives a substantial improvement in balance and communication between the actors, instruments in the case of music, due to the uniform dispersion of the energy in all directions. New arqjitectonica positions were also added on the stage in order to analyse the dynamic of the acoustic shell.

Carolina Coronado Theatre was inaugurated in The height from the ceiling to the main seating area is arquitectonlca than 15 metres, where the stalls were located, supported xcustica wrought iron columns Figure 1. March 01, ; Accepted: Sound system equipment – Part Conclusions Room acoustical simulation software has been used to predict the main acoustic parameters of the Carolina Coronado theatre. Simulation results after acoustic treatments To keep this report brief, only the results found in the study hypotheses of extreme situations are given in Table 3.
The first of these refers to the original situation of the hall without audience, and the second and third to the hall while unoccupied and occupied with the treatments described, respectively.
Audience and chair Absorption in Large Halls. Moreover, and as was pointed out above, this system can also be used to provide diffused reflections to the area of the public. Having carried out the solutions and treatments described new measurements were made in accordance with ISO International Organization for Standardization, and IEC International Electrotechnical Commission, to check that acoustic behaviour was as expected and that the necessary quality requirements for use as a theatre were complied with.
Innovative approaches to the design of symphony halls. Resumen El teatro Carolina Acuwtica fue inaugurado en It was designed in harmony to the creative spirit of the great halls. Taking into account the acoustic problem, the conservation requirements and the budget allocated for acoustic correction, three fundamental courses arquitectonkca action were adopted; first, an increase of sound absorption, using construction solutions formally, according to the space to be renovated; second, increasing the diffusion reflections, acusticx terms of geometry, from those reflective planes and surfaces which are causing prejudicial reflections; and finally, to re-design the stage space, in order to facilitate early reflections towards the audience, through a great soundboard in form of an acoustic shell.
The RT opt values arquitdctonica calculated following this expression: International Organization for Standardization. Preliminary acoustic measurements Acustia were made of in its original condition previously to the intervention in order to obtain its acoustic qualities in sufficient detail. Acoustic shell for theatrical performance One of the novel features of this intervention has been arquitedtonica use of a new concept of acoustic shell based on panels diffusing the sound over the stage, which by this dynamic makes it compatible with theatre activity and other more common uses, achieving different acoustic ambiences.

As the building opened inthe building, rehabilitated inshowed deficient acoustics performance and, for this reason, the Government of Extremadura decided to correct the acoustic problems.
Table 4 shows the STI values from each microphone position for computer simulation and final measurements. It can see the similarity of some results of the final acoustic measurement and the computer simulation, and the notable improvement of the parameters measured, which shows the utility of these techniques in acoustic renovation processes. Its original design resembles a classical opera theatre, having a arquitectobica horseshoe form, used throughout 19 th century. The results of this phase are summarised below Table 5 and Figure 7.
Room acoustical simulation software has been used to predict the main acoustic parameters of the Carolina Coronado theatre.
Before the renovation its volume-number of seats ratio and its reverberation time with audience, were far away from some recommended values. According to Arauit is possible to correlate the value of T 30,mid with the type of music that better can be played in the room. Journal of the Acoustical Society of America45 El teatro Carolina Coronado fue inaugurado en This work presents the acoustic evaluation and analysis carried out in the theatre.

The plan of the portuguese architect Coffino, which gave risen to its construction, is datedvery previous to other theatres which were built at that time in Extremadura, some of which have now disappeared.

Finally, new measurements were carried out of the acoustic conditions of the enclosure, the treatment having been completed, in order to check that the conditions were those hoped for and that the quality requirements necessary for use as a theatre are complied with.

It was also necessary for the treatment used not to alter the current appearance of the hall. On the basis of the results obtained, the 3-D model and its acoustic simulation were made with ODEON to give us a detailed analysis of the sound field of the hall on the basis of the acoustic parameters provided. As can be seen the reverberation times recorded are excessively high, making difficult the arquiectonica of the word, so it is necessary to increase absorption significantly at all frequencies.
One of the novel features of this intervention has been the use of a new concept of acoustic shell based on panels diffusing the sound over the stage, which by this dynamic makes it compatible with theatre activity and other more common uses, achieving different acoustic ambiences.

The positions of the microphones are showed in the Figure 2five in the stalls, two in the first gallery arquitectoica two in the second gallery.
