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. Audience and chair Absorption in Large Halls. Carolina Coronado Theatre was inaugurated in 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: 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.
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.
London, Applied Science Publishers. Principles and applications of room acoustics 1 st ed. Sound system equipment – Part 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. To keep this report brief, only the results found in the study hypotheses of extreme situations are given in Table 3.

Measurements were made of in its original condition previously to the intervention in order to obtain its acoustic qualities in sufficient detail. 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.
Moreover, and as was pointed out above, this system can also be used to provide diffused reflections to the area of the public. Journal of the Acoustical Society of America45 As in practice, STI values rarely exceed 0. 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.
Theory, Design and Application 1 st ed. The values Figure 8 are the result of averaging in three different points on the stage.

Other results found in these measurements not only confirmed the high reverberation time of the original enclosure EDT mid of 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.
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. All the simulations used were carried out in the most unfavourable situation: Acustica49 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 T 30,mid obtained for the occupied hall is 3. 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 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.
These measurements were made in all cases with the hall and the stage completely empty. Acoustics – measurement of room acoustic parameters – Part 1: El teatro Carolina Coronado fue inaugurado en Acoustic Absorbers and Diffusers.

Dynamic acoustic shell with diffusers in the acoustical treatment of Carolina Coronado Theatre, Almendralejo Badajoz, Spain. 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.
It was designed in harmony to the creative spirit of the great halls. This acoustic configuration was slightly helped by covering lateral walls with acoustic panels. 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, arquiitectonica check that acoustic behaviour was as expected and that the necessary quality avustica for use as a theatre were complied with.
Resumen El teatro Carolina Coronado fue inaugurado en 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.
Computer simulation To correct and to adapt the sound field inside the hall the acoustic simulation software ODEON The receiver-source distance from each positions of the microphones is showed in the Table 1.
As we can see in the Table 4generally, in the stalls acustifa in the balconies, the greater the distance from the receiver to the source, the lower the value of STI is. International Organization for Standardization.
