“…Using the GAP single number index, the acoustic quality of 8 churches (on the basis of which the calculation model was designed) was evaluated [14]. The GAP index can assess any acoustic Roman Catholic church, as shown in [10]. Using simulation studies, the acoustic parameters of the 3D model of the church assessed with the GAP index may be carried out while taking the presence of the audience into account [12].…”

“…Modified global indices are more strongly correlated with the new partial index of speech intelligibility s (STI) than traditional global indices with the old index S (RASTI). Index assessment can be conducted for any of the Roman Catholic churches, as shown in the example of St. Elizabeth of Hungary Church in Jaworzno Szczakowa [10], where the GAP and GI indices and GAP occ , taking into account the presence of the audience, were used. The assessment of acoustic conditions in the occupied church was possible after a testing simulation on the developed acoustic model of the church (Fig.…”

A comparative analysis of the index assessment of church acoustics using rasti and sti Analiza porównawcza wskaźnikowej oceny akustycznej kościołów z użyciem rasti i sti AbstractThe article presents modified global assessment indices, developed in previous studies, for measuring the acoustic quality of Roman Catholic churches: the four-parameter Gap index and the Gi index based on five acoustic parameters. The replacement of RASTI, previously used in the acoustic assessment of churches, with STI has broadened the scope of church assessment and contributed to an improvement in the accuracy of the proposed method. Verification of new calculation procedures was performed on the 12 churches included in the calculation model and, additionally, on another church.

“…Most of this research has focused on churches located in countries around the Mediterranean sea, resulting in less scientific literature regarding churches in northern Europe. While Polish researchers have made interesting analyses on some churches around the Baltic Sea [12,13] and there is research on some Russian churches [14], there is very little, if any, acoustic research on religious buildings in Scandinavia and, specifically, Sweden. The research presented in this paper sheds new light on intangible cultural heritage in this part of the world by presenting a room acoustic analysis on a digital reconstruction of Vadstena abbey church in Sweden.…”

Worship space acoustics have been established as an important part of a nation’s cultural heritage and area of acoustic research, but more research is needed regarding the region of northern Europe. This paper describes the historical acoustics of an important abbey church in Sweden in the 1470s. A digital historical reconstruction is developed. Liturgical material specific to this location is recorded and auralized within the digital reconstruction, and a room acoustic analysis is performed. The analysis is guided by liturgical practices in the church and the monastic order connected to it. It is found that the historical sound field in the church is characterized by the existence of two distinct acoustical subspaces within it, each corresponding to a location dedicated to the daily services of the monastical congregations. The subspaces show significantly better acoustic conditions for liturgical activities compared to the nave, which is very reverberant under the conditions of daily services. Acoustic transmission from the two subspaces is limited, indicating that the monastic congregations were visually and acoustically separated from the visitors in the nave and each other. These phenomena can be heard in the auralizations, which are presented as supplementary material.

“…Reverberation time plays a significant role in the design of school rooms [1], sacral rooms [2][3][4], auditoriums [5], theaters and concert halls [6], open-plan spaces [7], or others. This parameter has been investigated in many different works, a few of them mentioned below in the last years [8][9][10].…”

The influence of the distribution of sound absorbing materials on the estimation of reverberation time in rooms

et al. 2018

Abstract. Reverberation time in rooms depends on many factors, e.g. cubature, surface of envelopes, sound absorption coefficient of materials used for the construction of the envelopes, geometry of rooms or the distribution of sound absorbing materials. The arrangement of sound absorbing materials in rooms has an impact on the dispersion of acoustic field, yet theoretical calculation models do not take into account this impact. According to these models, regardless of the arrangement of sound absorbing materials, the reverberation time in a room will remain unchanged. The present paper investigates the above problem by means of computer simulations. For the needs of the simulation, three rooms with different dimensions were adopted, i.e. type 'p' -a cuboidal room with a square base, type 'd' -a cuboidal room (with one side of the 'p' room lengthened), type 'w' -a cuboidal room (with the height of the room lengthened 'p'). During the simulation, the way of acoustic field dispersion was being changed and its influence on the reverberation time in the rooms was being determined. The authors investigated two situations. The first one involved a non-dampened room, in which the sound absorbing material was being arranged differently. The second one involved a welldampened room, and the dispersion of sound field was analyzed depending on the location of the reflecting material.
