The florid performance of Opera always in place and the slow recovery from the pandemic by the public to be back to a frequent attendance of the artistical venues suggest the authors to analyze the acoustic behavior of the National Theatre of Zagreb by reflecting five specific scenarios. Starting from the acoustic measurements undertaken inside the National Theatre of Zagreb without any scenery in place, this research study compares the main acoustic parameters simulated with the scenery of Tosca related to three acts. A numerical model has been realized by faithfully reproducing the geometry and the architectural features of this historic performance arts space. Before the simulations, the absorption coefficients applied to the digital entities have been calibrated with the values gathered from the recorded impulse responses. After the calibration process, the acoustic simulations have been also carried out with the presence of audience at two percentages of occupancy.

How Much Does the Variety of Scenery and the Different Percentages of Audience Occupancy Affect the Indoor Acoustics at the National Theater of Zagreb?

Abstract

The florid performance of Opera always in place and the slow recovery from the pandemic by the public to be back to a frequent attendance of the artistical venues suggest the authors to analyze the acoustic behavior of the National Theatre of Zagreb by reflecting five specific scenarios. Starting from the acoustic measurements undertaken inside the National Theatre of Zagreb without any scenery in place, this research study compares the main acoustic parameters simulated with the scenery of Tosca related to three acts. A numerical model has been realized by faithfully reproducing the geometry and the architectural features of this historic performance arts space. Before the simulations, the absorption coefficients applied to the digital entities have been calibrated with the values gathered from the recorded impulse responses. After the calibration process, the acoustic simulations have been also carried out with the presence of audience at two percentages of occupancy.
