Room acoustical simulation software has been used to predict the main acoustic parameters aucstica the Carolina Coronado theatre.

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.

Simulation results after acoustic treatments To keep this report arquitectomica, only the results found in the study hypotheses of extreme situations are given in Table 3.

Objective rating of speech intelligibility by speech transmission index 4 th ed. Before the renovation its volume-number of seats ratio and its reverberation time with audience, were far away from some recommended values.

Other results found in these measurements not only confirmed the high reverberation time of the original enclosure EDT mid of 3. These measurements were made in all cases with the hall and the stage completely empty. Acusticx receiver positions were also added on the stage in order to analyse the dynamic of the acoustic shell. The basic acoustic solutions for this space, used mainly for theatrical activities, are aimed for the intelligibility of the word or the level of comprehension for the oral message, being optimal at all points in the hall, and the acutsica level, indicative of the amplification of the hall, being sufficiently high.

Its original design resembles a classical opera theatre, having a traditional horseshoe form, used throughout 19 th century. Preliminary acoustic measurements Measurements were made of in its original condition previously to the intervention in order to obtain its acoustic qualities in sufficient detail.

The reverberation time measured are excessively high, causing the sonority of the hall and, at the same time, an appreciable reduction of the intelligibility of the word and, hence, it is necessary to increase sound absorption significantly at all frequencies, without being able to reduce the volume as has been indicated.

March 01, ; Accepted: Table 4 shows the STI values from each microphone position for computer simulation and final measurements. Acoustic Absorbers and Diffusers.

As in practice, STI values rarely exceed 0. To keep this report brief, only the results found in the study hypotheses of extreme situations are given in Table 3. As we can see in the Table 4generally, in arquitectoonica stalls and in the balconies, the greater the distance from the receiver to the source, the lower the value of STI is. 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. The receiver-source distance from each positions of the microphones is showed in the Table 1.

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. Arrquitectonica is an open-access article distributed under the terms of the Creative Commons Attribution License.

These works are another example of the policy of renovation and rehabilitation of the stages of this region, making it possible for it, to return to its original function as a theatre. It was designed in harmony to the creative spirit of the great halls. Measurements were made of in its original condition previously to the intervention in order to obtain its acoustic qualities in arquitectonicz detail.

These measurements were carried out by a laptop-based system using WinMLS software. 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. 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.

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 atquitectonica of the hall on the basis of the acoustic parameters arquitsctonica.

To evaluate the advantages of the new acoustic shell the support parameter ST1, based on the ratio between the sound energy reflected back from the room in time interval of ms relative to the direct sound energy including the floor reflectionbeing the source receiver distance 1 m, proposed by Gadewas measured on the stage in four different positions, without the shell and with the nine ceiling clouds at 7, 8 and 9 metres over the floor of the stage.

The results of this phase are summarised below Table 5 and Figure 7. Reverberation time; room acoustics; acoustic shell; computer simulation; diffuser. Acoustic acustiica for theatrical performance 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.
