Preference Index of the Acoustic Quality Assessment of Sacral Sound Field

Abstract

The characteristics of sacral sound perception were surveyed by using two different measurements in four churches of the Ando [1] suggested that sound quality has four decisive parameters: A. initial Listening levels and inter-aural correlation The classical music Motif A, B and a chorus of poem were employed to evaluate the sound perception in the liturgy hall of churches by using Ando’s model. Furthermore, the questionnaire was implemented by using a five-point Likert scale of a thirteen audible perception dialogue. The results of the global index of these two measures are quite agreement. But the variation occurred at high reverberation of the lower frequency band with respective to the sense of hearing in such band which is a crucial element in sacral sound perception.
