This paper describes the acoustic evaluation of historical baroque church in Brazil - Igreja Nossa Senhora do Rosário de São Benedito (Church of Our Ladyof the Rosaryof St. Benedict), built in the 18th century. The evaluation was performed in three stages: 1) in situ measurements of reverberation time (RT), early decay time (EDT), definition (D50) and clarity (C80); 2) reproduction of field conditions in a computational simulation using ODEON room acoustics prediction software, and 3) statistical analysis of the data. The integrated impulse response method was used here, as recommended by the ISO/3382-1:2009 standard. Results were subjected to an analysis of variance (ANOVA) to test the accuracy of the model. The model can be considered accurate, especially as far as reverberation times are concerned.

The parameters of Definition, D50, and Reverberation Time, RT, described in the ISO 3382-1:2009 standard, were used in this study to evaluate the acoustic quality of classrooms which had been renovated. Following the aforementioned ISO standard, D50 and RT were measured via the impulse response method, using DIRAC 3.1 software. The analysis of RT in the classrooms after their renovation shows that this parameter increased, indicating that the quality of acoustic environments designed for the modern classroom is deteriorating. The analysis of the measured values of D50 led to the conclusion that, notwithstanding the increase in RT, many points inside the classrooms displayed good acoustic quality. This finding suggests that evaluations of the acoustic quality of classrooms should involve not only the analysis of RT but also of the parameter of Definition, D50.

This paper presents a preliminary assessment of the acoustics of the Guai?ra Theater. This is one of Brazil’s most important theaters, whose space is designed for presentations of symphony concerts, operas, ballets and plays. The acoustics of the main auditorium of the Guai?ra Theater was evaluated based on reverberation times calculated for the following conditions: 1) 1/3 of seat occupancy, 2) 2/3 of seat occupancy, and 3) full seat occupancy. In addition to these calculations, reverberation times were also measured following the guidelines of the ISO 3382-1: 2009 standard.

Air dome is an air supported structure, it is a building composed by one or more layers of continuous flexible membrane anchored to the ground, inflated and supported by pressurized air. In the present work are shown results of acoustic measurements inside an air dome. In this type of structure reverberation time values, at the medium frequencies, are over 8 s and therefore with an excessive reverberation is significantly reduced ability to speech understanding that during training phases does not correctly allow to understand the instructions of coaches. With use of a software for architectural acoustics it was evaluated a possible acoustic correction for reducing reverberation time, by introducing into the turned area of air dome some sound absorbing material.

The present work concerns the acoustic design for a former church converted into a chamber music hall. The current status of the hall was classified with an acoustic measurements campaign according to technical standards requirements. Focusing on literature theories, an accurate sound energy spatial distribution analysis led to the development of an acoustic intervention, not- invasive from a volumetric point of view. An array of hanging reflecting panels over the musicians' positions improves clarity C80 and sound strength G trends giving to the church an acoustic quality worthy of a concert hall. All the acoustic treatments were validated using a numerical model, calibrated through the measured values, and an acoustic simulation software in order to estimate the effect of the whole improvement proposal.

Occupant comfort in an indoor environment includes not only thermal qualities of the space but expands to other space performance attributes. For instance, acoustic performance of indoor rooms is seen to have a direct effect on the productivity levels of the occupants of the space. The integration of greenery system such as a living wall can be a possible sound insulation strategy. The aim of the current research was to obtain in situ acoustic measurements at four locations with living walls, and evaluate the overall potential of sound insulation of these living walls. In addition, the investigation included an assessment of the potential of integrating the living wall within the Paul Cocker Gallery, at Ryerson University’s Department of Architectural Science. The results showed that the living wall modules generated high levels of running waterfall, and pump and fan system noise. The results of the case study are presented in this paper.

This paper reports the study of a conference room inside a secondary school in Switzerland. The architectural approach developed focused on the choice of the room’s shape and materials, while the acoustic treatments, proposed had to provide a good insulation from exterior and adjacent rooms as well as a good speech intelligibility. Simulations run also with the software Odeon allowed to foresee the main acoustic indicators (T30, EDT, C80, D50 and STI) and therefore optimize the dimensions and positions of the acoustic treatments for different audiences. Moreover, the acoustic treatment included the vocal emission of the speaker without amplification systems. Acoustic measurement were carried out at the end of the building construction confirmed the good acoustic quality of the auditorium.

In this study, a method of mapping ray motions in three-dimensional geometrical spaces was theoretically established using the ray-tracing algorithm. The paths along which the acoustic ray propagates in enclosed rectangular and concave spaces are described according to the ray-tracing algorithm. The location and the direction of the acoustic ray at arbitrary points on the paths were explored. The largest Lyapunov exponents (LLEs) of the ray systems in the rectangular and concave spaces were determined using the Wolf algorithm based on the points on the propagation paths with equal length in the time series. A new chaotic concave geometry is produced with a positive LLE. The LLEs of ray dynamics between the two geometrical spaces were compared and the results showed that the ray moves in a regular fashion in the rectangular space with an LLE of 0 whereas the ray exhibits chaotic behavior in the concave space with a positive LLE. The acoustic fields in both of these spaces in were described by applying ray chaos to the building acoustics. The acoustic diffusion was evaluated based on the uniformity of the sound pressure levels at different positions in the sound field using Odeon room acoustics software. The results showed that the proposed model has the potential to simulate chaotic dynamics of acoustic rays in enclosed spaces.

Medieval and Renaissance halls are often used for musical events or conferences. These rooms have vaulted ceilings, while the surfaces are covered with plaster and marble. The acoustics of these places are not optimal for listening to musical performances or conferences. To make these environments acoustically usable, an acoustic correction must be made. A room built during the Renaissance period used for cultural events was considered as case study. From the acoustic measurements, it results that at mid-frequencies the reverberation time is about 4.5 seconds. The evaluation of the acoustic correction was carried out with a software for the architectural acoustics. The virtual model was analyzed first in the initial configuration and then with the insertion of sound-absorbing panels on the walls and under the ceiling with the vault. Subsequently, the acoustic correction was performed by installing sound-absorbing panels in the room. Acoustic measurements were taken with this new configuration, in the absence of the public, and the reverberation time at the mid-frequencies was reduced to 2.0 seconds as presented in the design project.

Lu, Yigang

Chinese traditional stages are unique in the history of the world's ancient theaters, so they have significant meaning in research on their acoustical characteristics. Among the many Chinese traditional stages, the cave-style stages and splay walls in Shanxi Province have special acoustic effects, which are simulated using a finite-difference time-domain approach in this paper. The conformal technique combined with perfectly matched layers is introduced into finite-difference time-domain equations for sound waves, which solves the acoustic problem of a curved boundary in open space. To verify the validity of the finite-difference time-domain model, simulated values are compared with measured values. Furthermore, the sound pressure distribution of several cave-style stage models and splay walls are simulated. According to the impulse responses, several room acoustical parameters, such as loudness, clarity and reverberation time, are analyzed. Moreover, a listening test based on a paired comparison method is conducted.

The church of the Holy Family in Salerno (Italy) built in 1971 radically revolutionized the spatial structure of pre-conciliar church building design. The circular stepped geometry of the roof required a complex work with the employment of shipyard workers to come out with a unique geometry. However, such futuristic geometry also resulted in challenging conditions for its acoustics, as they emerged when the construction was completed. In this paper, the results of measurements of the spatial distribution of the acoustic characteristics in this large space are reported. The analysis of the acoustic parameter values confirms the poor acoustic conditions for speech and music listening. With the help of modelling, the authors have investigated possible solutions for the acoustic correction of this modern architecture. This paper reports the conclusions of such a study.

The Sound of a Monumental Architecture
Fratoni, Giulia
University of Bologna
The present work is intended to be a scientific commentary on the ``''SynAsTex Korrektur'' sound performance by the German artist Florian Hecker. The choice of the venue for the performance fell on the rationalist atrium of the School of Engineering of the University of Bologna, which is part of a historical building dating back to the 1930s. The study tries to answer some questions. Which role can be played by the acoustics of a monumental atrium - which is made by marble and reflective surfaces - in an electronic performance? How much may the presence of the standing audience influence the room acoustics? Which are the peculiarities of the sound energy distribution in this kind of strongly non-diffuse sound field? The assessment of the acoustic condition was carried out through acoustic simulations, employing a ray-based approach.

There is limited research on noise exposure in multi-unit residential buildings (MURBs) despite the proven effects of noise on people’s physical and psychological health. This motivates the current study which aims to identify important noise sources in MURBs and investigate factors that impact acoustic comfort as well as determine the various impacts of noise on occupants. A survey was administered to collect subjective assessments of noise exposure and the effects of noise from 213 occupants. The findings show that building age, floor level, proximity to ongoing construction, existence of balcony, number of bedrooms, proximity to elevators and garbage chute are important building-related factors that impact noise annoyance. The results also show that personal and demographic factors, such as occupants’ age, length of residency, ownership status, relationship with neighbors, and willingness to pay for better acoustic conditions, significantly affect subjective responses. Even though both indoor and outdoor noises cause annoyance, outdoor noises, especially noise from traffic, construction and neighborhood activities, cause more annoyance and sleep disturbance compared to indoor noise sources. The findings also show some noise mitigating actions can have negative effects on indoor air quality and building energy consumption, as well as worsen the overall acoustic condition in buildings.

Performing arts spaces characterize a specific group of buildings always subject to intense studies under architectural other than acoustics point of view. In Italy, the acoustics of historical theatres, as Baroque Opera houses and Renaissance concert halls, is nowadays considered the most important physical aspect of the architectural heritage. This paper analyzes the acoustical characteristics of some important Italian theatres. In order to precisely compare the analogies of the selected theatres, only the architecture realized during the 18th century has been considered. The acoustics features have been obtained by using a pre-equalized omnidirectional sound source, which emitted an exponential sound signal (ESS) acquired by a dummy head and a B-Format microphone. This technique satisfies the standard requirements of the ISO 3382:2009 and has been compared with the innovative process realized by using a 32-channel individually controlled microphone (i.e. em32 Eigenmike®). This new generation of the microphone is able to create a 3D auralization by synthesizing any real-time variable directivity pattern. In this way, both graphical analysis and 3D sound playback can be the resulting methods of how to show the room impulse response (RIR) data measured inside any performing arts space.

The attention by the scholars to the acoustics of ancient open-air theatres is increased considerably through the centuries and among the historical buildings survived to nowadays the acoustics of the Roman theatre of Verona has not been deeply investigated, yet. In this paper, the outcomes of the acoustic survey undertaken in the Roman theatre has been analysed in two different ways: by a standard methodology representing the graphs of the acoustic parameters, and by the creation of a video showing in real-time the impulse response (IR) and relative reflections occurred at the surfaces of the cavea. The latest technique has been realised by using a multichannel spherical microphone array, which calls back the MIMO approach that is capable to have complete spatial control of the sound propagation through space. The authors of this paper illustrate a brief history of the theatre, including the description of the construction elements that characterise this important historical building, and two distinct procedures to show the results obtained after the survey, highlighting the coplanarity of explanation by using the MIMO approach, as followed by the second methodology.

In this paper, the acoustic characteristics of the ancient Roman theatre of Cassino are discussed. The theatre was built during the Imperial Age and was abandoned and destroyed after the Barbaric invasions. The theatre has been rebuilt in recent years and it is currently used for summer events ad performance. To measure the acoustic characteristics of this ancient theatre, the authors used a spherical omnidirectional sound source placed on the stage and in the orchestra. The results show that nowadays the theatre has a short reverberation time equal to 0.6 seconds due to the lack of the stage wall, which has not been rebuilt. The weak sound strength justifies the use of electro-acoustic amplification systems which during the summer season, are adopted to improve the acoustic experience in this ancient theatre.
