| Summary: | 碩士 === 朝陽科技大學 === 建築系建築及都市設計碩博士班 === 103 === The purpose of this study is further intended to quantify the influence of couple space in a hall on the relationship between the relative late lateral sound levels G and the listener envelopment, LEV. The tool of couple room simulation was ray-method in a computer, but preliminary matching the acoustic factors by way of the measurements in the ceremony hall of design school at Chaoyang University of Technology. The relationship between G and LEV was obtained by the adding subsequence reverberation energies with respective to the couple room effects in 4 halls. It was well known that GＬ taken behind 80 ms of the direct sound within the frequency range from 125~ 1000 Hz of sound correlates well with the sense of the LEV reported by Bradley （2000）. The results are: 1 the influences of other parameters objective with respective to GＬ,low+mid values occurred by the couple spaces added to specific locations of a hall; 2. the subjective rates of LEV was increased while the couple room were added to the halls through the audible system with the binaural impulse by beam-trace method.
