苏南地区不同教堂声学性能比较研究
Comparison of acoustic performance in different churches
摘要
Abstract
Churches are not built in China originally.They have been introduced to China through Western missionaries and have undergone many years of vicissitudes in China,forming a Chinese style that is very different from the traditional Western churches.In recent years,the number of congregation kept growing rapidly.More importantly,the church is an important place for evangelism,and has special requirements for the indoor sound field,and these requirements are inextricably linked with the function of the church.In order to study the influence of church internal forms and materials on the acoustic performance of churches in different periods,and to explore the relationship between church functions and acoustic needs,the author,through comparisons of field tests and software simulation analysis of several churches in some areas,comparatively studied the scale,the plane of the churchs,and randomly surveied the auditory experience of users(including clergy and believers,etc.) a random survey.The reverberation time used T20 and STI(Speech Transmission Index)was also used for comparison.After tests in churches,computer simulation would be used.Through comparisons between tests in situ and results of computer simulations,there are several conclusions emerged:(1)The acoustics indexes of the churches in different periods are quite different;former ones may more designed for preaching,which were mostly designed by the pastor;with development of functions in churches,requirements of reverberation time has changed;(2)The acoustics indexes of churches which have been specially designed for acoustics are very different,professional designed ones have better performance;(3)Even if the church reverberation time was too long,in actual use seems to have no special effect,especially for the congregation.However,the pastor may have a more sensitive feeling of church reverberation time.关键词
