Abstract The overall experience of religious practice is significantly affected by the acoustical properties of temples. Divine service is the most important act in the Orthodox Church, which equally demands intelligibility of speech for preaching and as well as adequate acoustics for Byzantine chanting as a form of a song-prayer. In order to better understand and contribute to unlocking the role of sound in these historical sacral spaces, this paper explores the acoustics of two well-preserved Orthodox churches, from Ljubostinja and Naupara monastery, built in the last building period of medieval Serbia (1371–1459). These represent two types of the Morava architectural style – triconch combined with a developed and compressed inscribed cross, respectively. Using EASERA software, we measured the impulse response for two sound source positions – in the altar and in the southern chanting apse, as the main points from which the Orthodox service is carried out. Thus obtained acoustic parameters (RT, EDT, C50 and STI) were further analysed, pointing out the differences in experiencing sound between naos and narthex, as well as how the position of the sound source influenced the experience of sound. Finally, we compared the results with previous archaeoacoustic research of the churches from the same building period.

Ljubostinja和Naupara中世纪修道院教堂的古声学研究

摘要寺庙的声学特性极大地影响了宗教实践的整体经验。神职是东正教教堂中最重要的活动，它同样要求宣讲的语言清晰度和传道的拜占庭式诵经足够的声音。为了更好地理解声音并在这些历史性spaces骨空间中发挥作用，本文探讨了保存完好的东正教教堂的声音，这两个教堂来自Ljubostinja和Naupara修道院，建于中世纪塞尔维亚的最后一个建筑时期（1371– 1459）。它们代表了两种类型的摩拉瓦建筑风格–三轮式分别与发达的和压缩的刻有十字架的十字架相结合。使用EASERA软件，我们测量了两个声音源位置（在祭坛和南部诵经后殿中）的冲激响应，作为进行正统服务的主要要点。进一步分析了这样获得的声学参数（RT，EDT，C50和STI），指出了naos和narthex之间体验声音的差异，以及声源的位置如何影响声音的体验。最后，我们将结果与之前同一时期的教堂的古声学研究进行了比较。以及声源的位置如何影响声音的体验。最后，我们将结果与之前同一时期的教堂的古声学研究进行了比较。以及声源的位置如何影响声音的体验。最后，我们将结果与之前同一时期的教堂的古声学研究进行了比较。
