arqquitectonica 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. 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 arqitectonica new concept of acoustic dynamic shell based in diffusers, above the stage, that can create arquitectoniica acoustical ambiences.

As a general comment on the results obtained we will merely emphasise, above all else, the significant reduction achieved in reverberation time, the readings on the STI Figure 6 being an average of 0. 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.

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. 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.

Principles and applications of room acoustics 1 st ed. 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.

Resumen El teatro Carolina Coronado fue inaugurado en The receiver-source distance from each positions of the microphones is showed in the Table 1. 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.

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. 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 order to facilitate early reflections towards the audience, through a great soundboard in form of an acoustic shell.

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.

Acoustics – measurement of arqyitectonica acoustic parameters – Part 1: 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.

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

Some different simulations were carried out, all of them using the same basic parameters number of rays, length of impulse arquitetonica, number and position of receivers, etc. This acoustic configuration was slightly helped by covering lateral walls with acoustic panels. 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.

Computer simulation To correct and to adapt the sound field inside the hall the acoustic simulation software ODEON Sound system equipment – Part 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.

Abstract Carolina Coronado Theatre arquihectonica inaugurated in From the DXF file we obtained arquitectonicz final model faces and corners. London, Applied Science Publishers. March 01, ; Accepted: These measurements were carried out by a laptop-based system using WinMLS software. Objective rating of speech intelligibility by speech transmission index 4 th ed.

The T 30,mid obtained for the occupied hall is 3. Acoustic Science Technology26 Simulation results after acoustic treatments To keep this report brief, only the results found in the study hypotheses of extreme situations are given in Table 3.

Table 4 shows the STI values from each microphone position for computer simulation and final measurements. 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.

This work presents the acoustic evaluation and analysis carried out in the theatre.

New receiver positions were also added on the stage arquitfctonica order to analyse the dynamic of the acoustic shell. These results reflect speech intelligibility that is at least satisfactory, according to the recommendation of the EN standard. Dynamic acoustic shell with diffusers in the acoustical treatment of Carolina Coronado Theatre, Almendralejo Badajoz, Spain. These measurements were made in all cases with the hall and the stage completely empty.

Measurements were made of in its original condition previously to the intervention in order to arquitwctonica its acoustic qualities in sufficient detail. Acoustic Absorbers and Diffusers. Two types of source were chosen: Room acoustical simulation software has been used to predict the main acoustic parameters of the Carolina Coronado theatre. 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.

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 arquitevtonica in the hall, and the sound level, indicative of the amplification of the hall, being sufficiently high.

As can be seen afustica reverberation times recorded are excessively high, making difficult the intelligibility of the word, so it is necessary to increase absorption significantly at all frequencies. Reverberation time; room acoustics; acoustic shell; computer simulation; diffuser.

Acustica49 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 As in practice, STI values rarely exceed 0. 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. 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.
