“…There are several studies about acoustic aspects on auditorium spaces, including field measurements (Rudno-Rudziński and Dziechciński, 2006;Kahle, 2013;Groendyke and Gipson, 2015;Jeon et al, 2015;Witew and Vorländer, 2016;Navvab and Heilmann, 2017;Ricciardi and Buratti, 2018), modelling or calculation (Garrido, et al, 2012;Mak and Wang, 2015;Wenmaekers et al, 2017), design or redesign (Ortega and Rivera, 2013;Brill et al, 2014;Coffeen, 2014;Szeląg and Flaga, 2015;Alam et al, 2016;Ortiz, 2016;Jambrošić et al, 2016;Lu et al, 2016;Barron and Kissner, 2017;Guthrie et al, 2017;Mahalingam, 2017) history and concepts (Adelman-Larsen, 2014;Mourjopoulos, 2016) The aim of this study is to presents the evaluation of the acoustic quality of a multiple use auditorium placed in a University Campus in São Leopoldo, southern Brazil.…”

The acoustic quality in enclosed spaces is defined by the constructive characteristics of the environment, which must be designed to increase the propagation of the sound. Therefore, the sound message to be transmitted, whether spoken, song or by music instruments, can be intelligibly captured by the listeners. Among the main characteristics that influence the sound behavior in rooms are its dimensions, its geometric shape and the finishing materials applied on their internal surfaces. Each room has different acoustic requirements, directly related to the purpose for which it is intended. Therefore, the professional responsible for the design and construction of these environments should analyze and recognize the needs of each case. In this way, the present case study presents the evaluation of the acoustic quality of a multiple use auditorium, at Unisinos Campus, in São Leopoldo, southern Brazil. Acoustic measurements were performed to calculate the Reverberation Time (T30) and the Early Decay Time (EDT) of the room. Afterwards, the modelling of the auditorium in the acoustic simulation software CATT-Acoustics was carried out, allowing the estimation of other objective acoustic parameters such as the Speech Transmission Index (STI), Definition (D50) and Clarity (C80). The results obtained through measurements and acoustic simulations show that the auditorium has satisfactory acoustic quality for speech, but it is not so suitable for receiving musical presentations. The model generated in the software also made it possible to simulate constructive solutions aiming to improve the acoustic quality of the room.

The effects of different building materials on sound field characteristics of the concert hall were studied by experimental study and numerical simulations. A single non-directivity excitation sound source in situ test was carried out. The acoustic analysis model of the multifunctional concert hall was established. The reverberation time, the early decay time, the speech transmission index and the sound pressure level (SPL) were tested. The architectural treatment solutions with or without sound absorption in the design ceiling, sound absorption on the side walls, the influence of ceiling form on acoustic characteristics, and the acoustic characteristics of different positions on the first and second floors were analyzed, respectively. Simulation results show that there was little difference in reverberation time at different reception points by using the same treatment solutions, and the speech transmission index increased with the distance of the reception point. The language performance of the positions on the second was better than on the first floor. The SPL decreased with increasing distance from the receiving point. The ceiling form had no significant effects on the acoustic characteristics of the multifunctional concert hall, and the reverberation time was smaller when acoustic materials were used in the ceiling than the side walls. Meanwhile, the language transmission performance in multifunctional concert halls was improved. The difference between the maximum and minimum sound pressure levels for a sound-absorbing material ceiling is less than that of a non-sound-absorbing material.
