“…The secondary reverberation due to the stage house coupling may become even a greater problem in the case of opera houses, where the volumes are much greater [59]. A similar problem may arise in those opera halls that are used for symphonic music as well, if not properly treated by either introducing absorption to the stage tower or addition of overhead reflectors [60]. In another study, the stage house coupling effect to the measurement consistency are discussed and guidelines are set for opera house field tests [61].…”

“…< 1dB), proving that the scaenae frons together with all the surrounding buildings behave as a single volume. Moreover, the high value of measured G (mean values equal to 8 dB) proves that the hybrid indoor-outdoor theatre contributes to significantly increasing the sound source level at the receivers, as it happens in indoor theatres [10,11]. With this purpose, the trend of G values as functions of sourcereceiver distance has been analysed.…”

In ancient open-air Roman theatres, the scaenae frons increases the directivity of the sound source to better convey the actors' speech to the audience. Since such an acoustic effect is closely related to the presence of architectural elements such as awnings and columns, specific insights are needed for each case. The present work concerns the acoustics of the Loggia Cornaro in Padua (Italy), an outstanding example of Renaissance columned portico ( 1524) with a well-preserved Roman-style scaenae frons intended to host open-air theatre performances. Acoustic measurements were performed in the Loggia and the adjacent forecourt according to ISO 3382 -1. In addition, a numerical model of this hybrid indoor-outdoor site was developed and tuned till the match with the measurements' outcomes. Bayesian multi-decay analyses determined the actual influence of the scenery on sound propagation throughout the audience area. The main results prove that the Loggia not only increases the sound source level but also leads to different multi-slope sound energy decays depending on the sound sources' location, which are typical traits of modern indoor theatres.

This article aims to review the development of acoustic computer simulation for performance spaces. The databases of Web of Science and Scopus were searched for peer-reviewed journal articles published in English between 1960 and 2021, using the keywords for “simulation”, “acoustic”, “performance space”, “measure”, and their synonyms. The inclusion criteria were as follows: (1) the searched article should be focused on the field of room acoustics (reviews were excluded); (2) a computer simulation algorithm should be used; (3) it should be clearly stated that the simulated object is a performance space; and (4) acoustic measurements should be used for comparison with the simulation. Finally, twenty studies were included. A standardised data extraction form was used to collect the modelling information, software/algorithm, indicators for comparison, and other information. The results revealed that the most used acoustic indicators were early decay time (EDT), reverberation time (T30), strength (G), and definition (D50). The accuracy of these indicators differed greatly. For non-iterative simulation, the simulation accuracies of most indicators were outside their respective just noticeable differences. Although a larger sample size was required for further validation, simulations of T30, EDT, and D50 all showed an increase in accuracy with increasing time from 1979 to 2020, except for G. In terms of frequency, the simulation was generally less accurate at lower frequencies, which occurred at T30, G, D50 and T20. However, EDT accuracy did not exhibit significant frequency sensitivity. The prediction accuracy of inter-aural cross-correlation coefficients (IACC) was even higher at low frequencies than it was at high frequencies. The average value of most indicators showed a clear systematic deviation from zero, providing hints for future algorithm improvements. Limitations and the risks of bias in this review were discussed. Finally, various types of benchmark tests were suggested for various comparison goals.
