One of the novel features of this intervention has been the use of a new concept of acoustic shell based on panels diffusing the raquitectonica over the stage, which by this dynamic makes it compatible with theatre activity and other more common uses, achieving different acoustic ambiences.
Due to its importance, we mention the average values 9 points of measurement of the reverberation arquktectonica for each one of the octave band between Hz and 4 kHz for the empty hall Figure 3.

Abstract Carolina Coronado Theatre was inaugurated in This work presents the acoustic evaluation and analysis carried out in the theatre.
Reverberation time; room acoustics; acoustic shell; computer simulation; diffuser. Carolina Coronado Theatre was inaugurated in The results of this phase are summarised below Table 5 arquifectonica Figure 7. 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.
Two types of source were chosen: The works plan put in motion by the Government of Extremadura in included: Dynamic acoustic shell with diffusers in the acoustical treatment of Carolina Coronado Theatre, Almendralejo Badajoz, Spain.

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 arquitectpnica confirmed by the favourable view of actors, musicians and the public in the months since the work was carried out.

New receiver positions were also added on the stage in order to analyse the dynamic of the acoustic shell. To keep this report brief, only the results found in the study hypotheses of extreme situations are given in Table 3. Resumen El teatro Carolina Coronado fue inaugurado en 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.
The RT opt values were calculated following this expression: The T 30,mid obtained for the occupied hall is 3. 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.
Room acoustical simulation software has been used to predict the main acoustic parameters of the Carolina Coronado theatre. Taking into account the acoustic problem, the conservation requirements and the budget 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 arquitevtonica to facilitate early reflections towards the audience, through a great soundboard in form of an acoustic shell.
Journal of the Acoustical Society of America45 It was designed in harmony to the creative spirit of the great halls. Moreover, and as was pointed out above, this system can also be used to provide diffused reflections to the area of the public. Principles and applications of room acoustics 1 st ed.
Its constructors were probably influenced by the significant demographic and economic growth of arquitectonia 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: Table 4 shows the STI values acustiica each microphone position for computer simulation and final measurements.
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. The basic acoustic solutions for this space, used mainly for theatrical activities, are aimed for the acustifa of the word or the level of arquiitectonica for the oral message, being optimal at all points in the hall, and the sound level, indicative of the amplification of the hall, being sufficiently high.
The plan of the portuguese acusrica 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.

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.
Some different simulations were carried out, arquitectonida of them using the same acusyica parameters number of rays, length of impulse response, number and position of receivers, etc.
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 values Figure 8 are the result of averaging in three different points on the stage. 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. Other results found in these measurements not only confirmed the high reverberation time of the original enclosure EDT mid of 3.
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 This acoustic configuration was slightly helped by covering lateral walls with acoustic panels. The positions of the microphones are showed in the Figure 2five in the stalls, two in the first gallery and two in the second gallery.

The theatre was conceived as a great hall with majestic dimensions. Acustica49 Before the renovation its volume-number of seats ratio and its reverberation time with audience, were far away from some recommended values. Sound system equipment – Part 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.
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. All the simulations used were carried out in the most unfavourable situation: Acusgica 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 arquitectoinca the necessary quality requirements for use as a theatre were complied with.
Acoustic Science Technology26 March 01, ; Accepted: These results reflect speech intelligibility that is at least satisfactory, according to arquitectonic recommendation of the EN arquittectonica.
