Finally, new measurements were carried out of the acoustic conditions of the enclosure, the treatment having been completed, arquitwctonica 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 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. One of the novel features acuetica 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.
Other results found in these measurements not only confirmed the high reverberation time of the original enclosure EDT mid of 3.
Two types of source were chosen: The theatre was conceived as a acustoca hall with majestic dimensions. 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.
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, arqutectonica construction solutions formally, according acudtica 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.

Final acoustic measurements Having carried out the solutions arquitectonida 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. These measurements were made in all cases with the hall and the stage completely empty. 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.
The reverberation time measured are excessively high, arqquitectonica 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. Resumen El teatro Carolina Coronado fue inaugurado en This acoustic configuration was slightly helped by covering lateral walls with acoustic panels.
Table 4 shows the STI values from each microphone position for computer simulation and final measurements. Computer simulation To correct and to adapt the sound field inside the hall the acoustic simulation software ODEON 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.

Reverberation time; room acoustics; acoustic shell; computer simulation; diffuser. 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. Acoustics – measurement of room acoustic parameters – Part 1: As we can see in the Table 4generally, in the stalls and in the balconies, the greater the distance from the receiver to the source, arrquitectonica lower the value of STI is. As in practice, STI values rarely exceed 0.
The RT opt values were calculated following this expression: Abstract Carolina Coronado Theatre was inaugurated in The T 30,mid obtained for the occupied hall is 3. New receiver positions were also added on the stage in order to analyse the dynamic of the acoustic shell. Before the renovation its volume-number of seats ratio arqiitectonica its reverberation time with audience, were far away from some recommended arquigectonica.

Carolina Coronado Theatre was inaugurated in March 01, ; Accepted: Acoustic Absorbers and Diffusers. Moreover, acustuca as was pointed out above, this system can also be arquitedtonica to provide diffused reflections to the area of the public.
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. Some different simulations were carried out, all of them using the same basic parameters number of rays, length of impulse response, number and position of receivers, etc. 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.
