#### 4.1.3 Simulation, Auralization, and Virtualization  
Works encompassed under this topic include: (1) simulations of various historical sites [63; 64; 65; 66; 67; 68; 69; 70; 72; 76; 77; 78; 79; 80; 81; 82; 83; 84; 85; 86; 87; 88; 92; 93] and (2) virtual reality and auralization models of the studied areas [94; 95; 71; 73; 74; 75; 82; 83; 84; 85; 89; 91; 92; 93]. The most relevant studies are described as follows:  
[PERSON] performed a 3D simulation of the Cathedral of Granada in Spain to study its acoustic characterization over three different historical periods [63]. [PERSON] carried out a similar investigation in Church San Luis de Los Franceses in Spain, where, using acoustic simulations, they studied the church changes throughout history [72]. Acoustic simulations were also performed at the Royal Palace of Caserta in Italy to study the spatial distribution [64]. [PERSON] performed an acoustic simulation of St. John Baptistery in Italy to understand its historical evolution [70]. [PERSON] made an acoustic simulation of the Islamic temple Aljama Mosque of Cordoba in Spain to obtain different constructive configurations of the past of this temple to reconstruct the historical sound [68]. [PERSON] presented the virtual and acoustic reconstruction of the 14 th-century church of the Jeromite monastery of Santa Maria de la Murta in Alzira. This work studies the acoustic evolution of the existing church in comparison with a reconstruction of the destroyed or poorly conserved rooms [75]. In [79], the acoustics of the Palais du Trocadero (1878-1937) were studied through simulations. Those simulations were based on the theory of sound perception and reflectionsof the first order. However, their method produced many echoes. In 1909, they tried to correct this problem by placing absorbent material, which did not work as expected. The conclusion was that the reflections were reduced using absorbent materials, but a total solution to the problem was not achieved due to surface forms. In [77], the prediction of [PERSON] was studied. This established that the Thomaskirche church had a shorter reverberation in [PERSON]'s time from 1723 to 1750 than in the 16 th century, as a result of the Lutheran alterations. They concluded that when the church in 1723 was empty, it had a lower T\({}_{30}\) value than today. In contrast, the church in 1539 was more reverberant than today, but when the church had the presence of people, the T\({}_{30}\) was less significant. In [81], researchers developed a simulation of the Bell Church to archive the best results from possible constructive materials. The absorption coefficient was acquired using an impedance tube to achieve a similar simulation to the original place. In [78], the authors studied the proscenium of The Alighieri Theatre in Ravenna. They concluded that the proscenium increased the sound force of the soloists, but the intelligibility was reduced. In [67], the authors developed a simulation in the archaeological site named Las Pailas in Argentina to determine the best places to see and hear correctly around the place. Additionally, [PERSON] carried out acoustic simulations of the theaters Taormina, Pompeil, and Benevento in Italy to estimate their acoustic features, considering that they were crowded with people. They concluded that acoustics change according to the geometry of the theater and it is influenced by the audience [65]. In [76], researchers developed the simulation of the Lazarica Church to study the acoustic and construction traditions of the place. The study of [PERSON] was carried out in the Roman Forum, Italy. Initially, they sought to identify the best areas for holding conferences. Once those points were determined, they conducted acoustic simulations of the place to know the approximate number of people who would simultaneously listen to a meeting or event [69]. [PERSON] also developed a simulation of Beaulieu Abbey. They found that it was constructed for promoting sacral music rather than intelligibility [80].
