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.
Its renovation was done respecting faithfully the original appearance of the hall, without changes in the raised stage, seating area or walls and only including a new concept of acoustic dynamic shell based in diffusers, above the stage, that can create different acoustical ambiences.
To keep this report brief, only the results found in the study hypotheses of extreme situations are given in Table 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.
These results reflect speech intelligibility that ackstica at least satisfactory, according to the recommendation of the EN standard.

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. 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.
The works plan put in motion by the Government of Extremadura in included: Innovative approaches to the design of symphony halls. It was also necessary for the treatment used not to alter the current scustica of the hall. 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 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.
As a general comment on the results obtained we will merely emphasise, above all else, the significant reduction achieved acustixa reverberation time, the readings on the STI Figure 6 being an average of 0.

Conclusions Room acoustical simulation software has been used to predict the main acoustic parameters of the Carolina Coronado theatre. Objective rating of speech intelligibility by speech transmission index 4 th ed.
These measurements were made in all cases with the hall and the stage completely empty.
These measurements were carried out by a laptop-based system using WinMLS software. These works are another example of the policy of renovation and rehabilitation of the stages of this region, making it arquitsctonica for it, to return to its original function as a theatre. Resumen El teatro Carolina Coronado fue inaugurado en 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.
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.
The RT opt values were calculated following this expression: Other results found in these measurements not only confirmed the high reverberation time of the original enclosure EDT mid of 3. 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.
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.

Journal of the Acoustical Society of America45 The values Figure 8 are the result of averaging in three different points on the stage. 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.
New 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 sound level, indicative of the amplification of the hall, being sufficiently high.

From the DXF file we obtained a final model faces and corners. This acoustic configuration was slightly helped by covering lateral walls with acoustic panels. Acoustic Absorbers and Diffusers. March 01, ; Accepted: Abstract Carolina Coronado Theatre was inaugurated in 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.
Room acoustical simulation software has been used to predict the main acoustic parameters of the Carolina Coronado theatre. Acoustic shell 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.

London, Applied Science Publishers. Acoustics – measurement of room acoustic parameters – Part 1: Due to its importance, we mention the average values 9 points of measurement of the reverberation time for each one of the octave band between Hz and 4 kHz for the empty hall Figure 3.
This work presents the acoustic evaluation and analysis carried out in the theatre. The results of this phase are summarised below Table 5 arquitfctonica Figure 7. Carolina Coronado Theatre was inaugurated in Before the renovation its volume-number of seats ratio and its reverberation time with audience, were far away from some recommended values.
