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.

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. Acoustic Science Technology26 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.
Theory, Design and Application 1 st ed. 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. The values Adustica 8 are the result of averaging in three different points on the stage.
Audience and chair Absorption in Large Halls. To keep this report brief, only the results found in the study hypotheses of extreme situations are given in Table 3. Taking into account the arqiutectonica 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.
Acoustics – measurement of room acoustic parameters – Part 1: 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. New receiver positions were also added on the stage in order to analyse the dynamic of the acoustic shell.
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 acusrica disappeared.
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.
Carolina Coronado Theatre was inaugurated in 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. Reverberation time; room acoustics; acoustic shell; computer simulation; diffuser.
Two types of source were chosen: 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. 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.

Innovative approaches to the design of symphony halls. On the basis of arquitectonida results obtained, the 3-D model and its acoustic simulation were made with ODEON acuustica give us a detailed analysis of the sound field of the hall on the basis of the acoustic parameters provided.
The receiver-source distance from each positions of the microphones is showed in the Table 1. As in practice, STI values rarely exceed 0. These measurements were made in all cases with the hall and the stage completely empty. Moreover, and as was pointed out above, this system can also be used to provide diffused reflections to the area of the public.
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. 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 arquitectonuca clouds at 7, 8 and 9 metres over the floor of the stage.

These works are another example of the policy arquitectoniica renovation and rehabilitation of the stages of this region, making it possible for it, to return to its original function as a theatre. Principles and applications of room acoustics 1 st ed. The works plan put in motion by the Government of Extremadura in included: This work presents the acoustic evaluation and analysis carried out in the theatre.
Before the renovation its volume-number of seats ratio and its reverberation time with audience, were far away from some recommended values. 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.
The T 30,mid obtained for the occupied hall is 3. The theatre was conceived as a great hall with majestic dimensions.

acusyica 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.
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.
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 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.
Other results found in these measurements not only confirmed the high arquitectonida time of the original enclosure EDT mid of 3. It was also necessary for the treatment used not to alter the current appearance of the hall.
