Análisis acústico del Auditório Padre Werner em Unisinos

Abstract

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.

Research on the Acoustic Environment of Heritage Buildings: A Systematic Review

“…Research on the acoustic environment of museums, auditoriums, and other non-acoustic spaces focuses more on the evaluation of indoor acoustic effects corresponding to the types of acoustic activities, and the research method is a combination of field measurements and model simulations. Stumpf-Gonzalez et al [44] evaluated the acoustic quality of a multipurpose auditorium at the Unisinos campus in Sao Leopoldo, Brazil, and modelled the auditorium using the acoustic simulation software Cat-Acoustics. However, it is not suitable for music presentations.…”

Análisis Acústico del Teatro Nacional de Costa Rica a partir de sus Respuestas Impulsionales

“…La respuesta impulsional de una sala es la representación temporal de su función de transferencia, la cual relaciona cualquier fuente de sonido ubicada dentro de ella, con el micrófono o receptor que se utilice para registrar el sonido producido. La respuesta impulsional engloba las características acústicas del espacio y permite estimar indicadores que permiten evaluar de forma objetiva la calidad de la experiencia auditiva de quienes se encuentran dentro de la sala [3].…”
