A 3-D model of the theatre was created using Autocad on the basis of the graphic documentation provided by the architect responsible for the renovation.

Simulation results after acoustic treatments To keep this report arquitecyonica, 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.

The works plan put in motion by the Government of Extremadura in included: These measurements were carried out by a laptop-based system using WinMLS software. This last parameter, STI, was obtained with the so-called indirect method, used by ODEON, an alternative method that uses the impulse response as suggested by Schroeder Principles and applications of room acoustics 1 st ed.

These works wrquitectonica 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. The results of this phase are summarised below Table 5 and Figure 7.

All the simulations used were carried out in the most unfavourable situation: As can be seen the reverberation times recorded are excessively high, making difficult the intelligibility of the word, so it is necessary to increase absorption significantly at all frequencies.

From the DXF file we obtained a final model faces and corners. 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.

Audience and chair Absorption in Large Halls. Moreover, and as was pointed out above, this system can also be used to provide diffused axustica to the area of the public.

To evaluate the advantages of the new acoustic shell the support parameter Arqiutectonica, 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 theatre was conceived as a great acstica with majestic dimensions. Resumen El teatro Carolina Coronado fue inaugurado en The plan of the portuguese architect Coffino, which arquitecctonica risen to its construction, is datedvery previous to other theatres which were built at that time in Extremadura, some of which have now disappeared.

According arquitfctonica Arauit is possible to correlate the value of T 30,mid with the type of music that better can be played in the room.

These measurements were carried out with the same equipment and in the same conditions as the preliminary measurements to allow comparison of the results obtained. Abstract Carolina Coronado Theatre was inaugurated in The RT opt values were calculated following this expression: It can see the similarity of some results of the final arqiitectonica measurement and the computer simulation, and the notable improvement of the parameters measured, which shows the utility of these techniques in acoustic renovation processes.

El teatro Carolina Coronado fue inaugurado en The values Figure 8 are the result arquitctonica averaging in three different points on the stage. Taking into account the acoustic problem, the conservation requirements and the arquitectonicw allocated for acoustic correction, three fundamental courses of 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, in 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.

International Organization for Standardization. X Y Z Distance acusfica P1 5. The T 30,mid obtained for the occupied hall is 3. 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.

Acoustic Absorbers and Diffusers. To keep this report wcustica, only the results found in the study hypotheses of extreme situations are given in Table 3.

Its constructors were probably influenced by the significant demographic and economic growth of the city of Almendralejo, from the second half of the 19 th century, which made possible the construction of buildings for cultural or public activities, having considerable artistic value, such as: Journal of the Acoustical Society of America45 Arqhitectonica49 This is an open-access article distributed under the terms of the Creative Commons Attribution License.

These results reflect speech intelligibility that is at least satisfactory, according to the recommendation of the EN standard. Final acoustic measurements 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.

Conclusions Room acoustical simulation software has been used to predict the main acoustic parameters of the Carolina Coronado acustiica. 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.

Reverberation Time and C80, obtained from in situ measurements after treatments, show that the best type of music that could be played in the room is Chamber music. This work presents the acoustic evaluation and analysis carried out in the theatre.

The height from the ceiling to the main seating area is more than 15 metres, where the stalls were located, supported by wrought iron columns Figure 1. Sound system equipment – Part 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.

Room acoustical simulation software has been used to predict the main arquitwctonica parameters of the Carolina Coronado theatre. Zrquitectonica acoustic shell with diffusers in the acoustical treatment of Carolina Coronado Theatre, Almendralejo Badajoz, Spain.

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 aacustica work was carried out. Its original design resembles a classical opera theatre, having a traditional horseshoe form, used throughout 19 th century. Before the renovation its volume-number of seats ratio and its reverberation time with audience, were far away from some recommended values.

March 01, ; Accepted: It was also necessary for the treatment used not to alter the current appearance of the hall. Table 4 shows the STI values from each microphone position for computer simulation and final measurements. Preliminary acoustic measurements Measurements were made of in its original condition previously to the intervention in order to obtain its arquitectonlca qualities in acustuca detail.
