“…In addition, the C 50 values related to all the acts have similar trends; however, graph (c) shows an upward shift of 0.3 dB between values of Act II and III, and a further upward shift of 0.4 dB between values of Act III and I. The simulations carried out with the presence of the audience, although no variance has been found between 50% and 100% occupancy, shift upward the curve of similar trend, to be 0.3 dB above the values related to Act I [24].…”

The performance of opera and the post-pandemic slow recovery of the public, who have been hesitant to return to frequent attendance of cultural venues, has inspired the authors to analyze the acoustic behavior of the National Theater of Zagreb, by reflecting five specific scenarios. Starting from acoustic measurements undertaken inside the National Theater of Zagreb without any scenery in place, this research study compares the main acoustic parameters simulated with the scenery of Tosca in three different acts. A numerical model was realized by reproducing the geometry and the architectural features of this historic performance arts space. Before the simulations, the absorption coefficients applied to the digital entities were calibrated with the values gathered from the recorded impulse responses. After the calibration process, the acoustic simulations were also carried out with the presence of an audience at two percentages of occupancy.

“…Unlike other studies, Platz used meta-analysis to study the audio-visual relationship, and it turned out that visual component was an important factor in the communication of meaning [13]. In recent years, the specific features of sound sources in the concert halls were studied, including loudness [14] , dynamic of the orchestra [15,16] and stage acoustics [17,18].…”

Traditional Chinese performance buildings and performing arts are different from those in the west.However, sound quality evaluation factors for western halls have been used in traditional Chinese performance buildings for a long time. In this study, grounded theory was used to establish a sound quality evaluation system for traditional Chinese performance buildings. The subjective evaluation system for a traditional Chinese performance building was divided into the following six aspects: loudness dominant (loudness, definition, loudness balance, stage support (overall), and spaciousness); frequency dominant (brightness and fullness); reflected sound dominant (crispness, richness, harshness, and fusion); direction dominant (envelopment and directivity); quietness; and cultural cognition. The evaluation dimensions of western and traditional Chinese performance buildings were compared. In the Chinese evaluation system, the preference for loudness and brightness was higher than that in the western system. Moreover, crispness, harshness, and cultural cognition were not common in the western evaluation system, whereas envelopment and directivity were rarely mentioned in traditional Chinese evaluation system. Finally, the reasons for the differences between the two evaluation systems were analysed according to the architectural form, performance content, and culture. Envelopment, directivity, and quietness were found to be related to the differences in the architectural form and structure. The preference for brightness, crispness, and definition may be related to the form of performance. The 'competitiveness' and 'renao' (jollification) in traditional Chinese opera performances, as well as aesthetic pursuits had significant effects on the cultural differences.

Acoustic Characterization and Quality Assessment of Cremona’s Ponchielli Theater

2023

View full text Add to dashboard Cite

The Ponchielli theater of Cremona was built in 1808 after a fire destroyed the old wooden structure. The interior, the architecture and the shape of the plan layout are reminiscent of the Teatro alla Scala, Milan, a masterpiece by the architect Piermarini, albeit on a smaller scale. The four orders of balconies crowned by the top gallery are typical features of a 19th Century Italian Opera theater. Acoustic measurements have been undertaken across the stalls and in some selected boxes according to ISO 3382. The main acoustic parameters resulting from the measurements have been used for the acoustic calibration of a 3D model representing the Ponchielli theater. The calibration has been used to compare different scenarios involving the acoustic response of the main hall at 50% and 100% occupancy. The outcomes indicate that no significant change can be detected when the seats are provided with robust upholstery, which can be considered a positive result, especially for the actors who are not forced to change their effort between rehearsal and live performance. In order to contextualize the measured values in relation to the optimal ones, a comparison with other Italian Opera theaters provided with similar architectural characteristics has been carried out. Overall, the findings indicate that the acoustics of the Ponchielli theater are suitable for both music and speech in line with the other selected theaters, as these places were mainly created for multifunctional purposes in the 19th Century.
