“…In this way, they participate in the process of greater social inclusion and expanding inclusivity in cities [56]. The potential for the emergence of POPS involving theaters and their activities, among other things, influences a better appreciation of cities and the public spaces that occur in them by restoring previously inaccessible spaces to the social and economic mainstream [57,58]. In Warsaw, an example of implementing the idea of POPs is the design of the Ochota Theatre, made by Janusz Marchwi ński, which fits in with its function and form in this type of space transformation (Figure 11).…”

Theater as a place, but also as a field of human and team activity involving the creation of performances performed in the presence of the viewer, has a centuries-old history. This study aims at examining the links between theatre architecture/space and public spaces, trying to answer to what extent these objects have become attractors in its space and how they affect the activity of cultural and social life. The subjects of the study are Warsaw theatres, both historical and contemporary, in the context of their impact on the surrounding public spaces. A specific methodology was elaborated to evaluate potential impacts. According to the spatial relations between the theatre and its surroundings, they are clustered in the following typologies: emanation, isolation, and interference theatre. The research methods applied for defining and solving the scientific problem are: (i) critical analysis, (ii) comparative analysis, (iii) observation without intervention, and (iv) intuitive method based on the author’s personal experience. The conclusions are based on empirical research, with particular emphasis on the research material obtained by field research. The results of the research allow one to draw conclusions regarding the influence of theatrical places on public spaces in the city structure. The mission of the theater is changed, activating events and building social bonds. Theater space and its surroundings are shaped in accordance with these new standards and social expectations to be transformed into a public space of a cultural nature. Thus, presently, urban theatrical space is a site for spectacle, with a social and cultural mission. Theater space and its surroundings should be shaped in accordance with changing standards and social expectations, and it should be a public space of a cultural nature.

“…Previous research studies have already used a similar technique for regular shoebox room volume [33], but the innovation of these acoustic maps consists of the visualization of the IRs in a 360 • view applied to a 19th century opera theatre with a particular volume shape [13]. On the image/video perspective, the parameter settings include the step size and frame rate, which are involved in the realization of the video flow.…”

Rapid technological advances in recent decades have led researchers to refine the accuracy of their studies. In the field of acoustics, the impact of new devices is noticeable, especially in the investigations of cultural heritage buildings. The selection of a seat in theatres and concert halls has always been a concern, since the live experience of artistic performance depends on the quality of hearing and sight view. This paper deals with the elaboration of 360° acoustic maps made in the National Theatre of Zagreb, one of the opera theatres investigated with the Sipario project. The analysis of the main acoustic parameters has been carried out, starting with site measurements describing the acoustic response at various representative points of the main hall by covering the audience area. In addition, acoustic maps have been created for some selected positions based on a 3-degree-of-freedom (3dof) technique that allows a panoramic visualization of the impulse responses (IRs). This methodology completes the determination of early and late reflections that contribute to the acoustic quality of a place. In addition to the interest of experts in acoustics, this methodology can also be adopted by music lovers who can find a reasonable explanation for seat selection when booking their tickets.

“…Other research studies take these cultural heritage buildings as an opportunity to conduct acoustic simulations and potential improvements that can be supported with the adaptations due to compliance with the standard regulations in the field of health and safety [3]. During the COVID-19 pandemic, numerous research studies were conducted on audience attendance as the pandemic could cause a change in the habits of building users [4]. On this basis, various investigations on live virtual reality performances have been undertaken [5,6] to make theatrical performances available at a domestic price since the use of only a pair of headphones in combination with a head-mounted display (HMD) is required.…”

Acoustic Characterization and Quality Assessment of Cremona’s Ponchielli Theater

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.
