“…Figure 7: Measured Reverberation Time (T30) overlay for all locations and the spatial average for sources (a) S1 and (a) S2.Based on the Brazilian Standard NBR 12179:1992[34], the optimum Reverberation Time for the 500 Hz frequency band, considering a volume of 1700 m 3 was extracted and presented in Table1, according to the room type or activity. From Figs (7). a-b, the average Reverberation Time is approximately 2.4 s. Comparing it with the optimum values of Table1, the Itacuruçá Church is presenting much higher Reverberation Time than the expected for a Protestant church.…”

“…The T30 as function of frequency, for all receivers, was calculated in 1 octave frequency band, as shown in Fig. (7), as well as the spatial average, calculated according to ISO 3382-1 (arithmetic average of individual parameters). The averaged T30 at 500 Hz frequency band is 2.4 seconds.…”

“…Several aspects might contribute to modifying the natural acoustic response: layout and material changes, such as chairs or bench materials; the addition of absorptive materials, such as curtains, cushions, and paintings; the sound source locations, such as choir position or the introduction of electro-acoustic systems. Furthermore, historical and new churches were built or adapted to serve as "multi-purpose" or "multifunctional" temples, sometimes serving different religions and doctrines [6][7][8]. This situation poses a difficult task to acousticians since they must design solutions that provide high intelligibility to the congregation to understand the spoken message clearly, but at the same time, create an environment with spaciousness, vivacity, and brightness for musical activities [9][10][11].…”

This paper presents the acoustical evaluation of a representative evangelical church in Rio de Janeiro, Brazil. The analysis, performed through measurements and simulations, has shown that the acoustic field needs to be more appropriate for the temple’s actual use. The analysis measured the impulse responses at 14 positions from 2 source locations and calculated Reverberation Time and Clarity Factor acoustic parameters. According to the literature and the ISO standards, the Reverberation Time was considered higher than the optimum value for both speech or music. An acoustic model for the temple was developed using the BRASS simulator. The simulation results were compared to measured data to validate the acoustic model. Based on that and aiming to achieve optimum acoustic parameters, a new model was proposed to evaluate alternatives to adequate the acoustical characteristics of the temple. The strategy to develop the final model and to achieve the target Reverberation Time is presented and discussed. An acoustic intervention is then proposed and evaluated using simulated data. The results obtained with the proposed changes, which considered the inclusion of perforated panels and carpet in some walls, were adequate, providing Reverberation Time in accordance to the standards and significant improvement to Clarity for music and speech.

“…Excessive reverberation time is a common occurrence in contemporary Catholic churches [3][4]. A study of two contemporary Italian churches built after 2000 indicated the beginning of a new acoustic trend towards designing churches with significantly reduced reverberation time [5].…”

The investigation involved 18 contemporary churches in Poznań, Poland. Out of all the facilities, 5 are of the twostorey type, which constitutes 23 investigated interiors in total. E-sweep signal was generated and parameters that the literature considers basic were measured to assess acoustic properties of the sacred interior: RT, EDT, Ts, C80, C50, D50, STI. A gunshot was applied as an additional sound source, and a control measurement was taken in selected points. The timeframe of the construction of the selected churches covers facilities erected after 1965 until 2018. Another criterion for the selection was different internal volumes, which vary from 315 m³ to 16 800 m³. Also, the layout of the interiors varies; longitudinal, axial and central-plan churches were selected. Acoustics of the sacred interior are very much dependent on its architectural style, which, to a great extent, determines acoustic properties of the interior. Many contemporary churches have bad acoustics, which raises a question how it is possible, while so much is known about acoustics these days, to erect public utility buildings that practically serve no useful purpose in the sound sphere. The main research issues discussed in the context of relations of architecture with interior acoustics are the scale of the facility, finishes and structure of the contemporary church.

“…Given the similar approach to the concepts, the goal of this paper is to show the importance of the acoustical simulations during the planning design, as the most delicate phase of the project, which highlights the issues that should be solved in order to achieve a good sound perception inside historical buildings. To achieve this goal, measurement techniques and results are critically compared, in line with the project intentions to improve the definition and the sound quality [2].…”

This paper compares two acoustical projects, applied to the S. Dominic church of Foligno and Imola, which are subject to a permanent and temporary conversion respectively, to places dedicated for listening to live music. Sets of measurements have been undertaken before the acoustical treatments in order to calibrate the digital model; in Foligno, the measurements have also been performed after the installation of the acoustical features, to check if the aims have been achieved. Between the proposed acoustical projects, only one has been realized in Foligno, with the artistic activity still running inside the auditorium. The challenge to adjust the acoustics of reverberant rooms like churches to host musical venues has been achieved with a good quality of sound perception. In particular, in S. Dominic church of Foligno, the goal has been hit after many digital simulations that calibrated the redirection of the sound towards the sitting areas.
