“…Once the model was validated for the empty theatre (Scenario 1, as Figure 8a), the absorption coefficient of the chairs was modified to simulate the presence of the audience in the hall (Scenario 2). The value of absorption coefficients of the chairs has been replaced with tissue's coefficient, as done in the previous study, that achieved excellent results [26]. The presence of the audience in the stalls, galleries, and Royal box is important to understand whether it can negatively affect the overall acoustics of the theatre and if it involves variations of the room's acoustics parameters.…”

The Eszterháza Opera House was a theatre built by the will of the Hungarian Prince Nikolaus Esterházy in the second half of the 18th century that had to compete in greatness and grandeur against Austrian Empire. The composer that inextricably linked his name to this theatre was Haydn that served the prince and composed pieces for him for many years. The Opera House disappeared from the palace complex maps around 1865 and was destroyed permanently during the Second World War. This study aims to reconstruct the original shape and materials of the theatre, thanks to the documents founded by researchers in the library of the Esterházy family at Forchtenstein, the Hungarian National Library, and analyze its acoustic behavior. With the 3D model of the theatre, acoustic simulations were performed using the architectural acoustic software Ramsete to understand its acoustical characteristics and if the architecture of the Eszterháza Opera House could favor the Prince’s listening. The obtained results show that the union between the large volume of the theatre and the reflective materials makes the Opera House a reverberant space. The acoustic parameters are considered acoustically favorable both for the music and for the speech transmission too. Moreover, the results confirm that the geometry and the shape of the Eszterháza Opera House favored the Prince’s view and listening, amplifying onstage voices and focusing the sound into his box.

“…This means that the Valli theatre has a good response for both speech and music performance. Following the research studies by Reichardt and others [11][12][13]41], the optimal values for speech clarity index (C 50 ) would be ≥ 3 dB. In the Valli theatre, this parameter floats between -2 and +2 dB at low and high-frequency bands, respectively, as shown in Fig.…”

The characteristics of a performing arts space have a great influence on the experience that both artists and audiences have during a show. Therefore, it is of great importance to understand the sound field behaviour, the lighting, and the thermo-hygrometry of the ambient conditions existing inside this cultural heritage. The aim of this paper is the presentation of a complete assessment in relation to the comfort of an Opera theatre on its whole. As such, it has been undertaken a study in relation to the acoustic listening situations other than to the parameters related to the light level and temperature comfort of the Valli Theatre of Reggio Emilia. The acoustic characterization has been undertaken in line with the ISO 3382 standard measurements procedure by capturing the room impulse response (RIR), while the light intensity has been studied by using the lux meter. In addition, the thermo-hygrometer has been used to photograph the comfort related to temperature and relative humidity inside the main hall.

“…The latter includes a high level of thermal comfort especially without any specific heating system, also balancing costs and performance [1,2] and high levels of sound insulation from external and internal noise and the evaluation of the sound propagation. Acoustic measurement could be utilized for emulating sound propagation of musical instruments as brasses and trumpets [3], including non-linearities [4] and the analysis of sound propagation is particularly relevant for offices, auditorium [5,6] and theatres [7,8] for the perception of sound [9]. Regarding the new technologies to improve the energy performance of the building, a recent covering technology used in the construction of the roof system is the green roof.…”

This study focuses on the application of coconut fibre insulators, an insulating material rarely utilized in the Mediterranean context. Despite its undoubted thermal performance, some queries are related with of his thermo-hygrometric behavior. More precisely, during the use of coconut for covering building for realizing green roofs, which represent a technological solution often adopted in the case of sustainable buildings or nearly zero energy building. Green roofs represent a valid constructive solution with high thermal performances, adopted in existing and new buildings. This paper investigates the thermo-hygrometric behavior of the concrete and Cross Laminated Timbre slabs, insulated with coconut fibreboards (CF) such as an alternative synthetic insulator, referred to a series of different green roofs scenarios. The results show that coconut fibre insulations are equally comparable to natural and synthetic materials. Therefore, coconut fibre could represent a good chance for realization of green roof having high thermal performance and hygrothermal behavior in the same time. This material could be an alternative solution to the normal synthetic materials actually used, in a perspective of sustainable architecture.
