本研究藉由音樂廳內部附加耦合空間,以延伸空間後續殘響聲能,探討影響室內聲場之聲音心理包被感(LEV)多寡為目標。實驗對象為朝陽科技大學設計學院大禮堂,並於大禮堂同時進行音響參數實測及藉由軟體音線法模擬附加耦合空間效應為工具,進行預備實驗並調整軟體聲場模擬設定為目的;並陸續以四個廳堂觀察在加設耦合空間後Bradley (2000)所建議室內聲源在125~1000Hz頻段及初期80ms之後續能量(later energy)的聲場 G值(GL,low+mid),影響聲音心理包被感之增減效益。實驗結果分析獲得以下具體成果:1. 利用各種可能之附加座位區上方耦合空間對於G值的影響,探討對於空間聲場其他物理量之影響。2. 以電腦模擬聲場附加耦合空間,利用可聽化之聲源樣本,證實主觀心理包被感(LEV)之提升。 實驗結果分析獲得以下具體成果: 1. 利用各種可能之附加座位區上方耦合空間對於G值的影響,探討對於空間聲場其他物理量之影響。 2. 以電腦模擬聲場附加耦合空間,利用可聽化之聲源樣本,證實主觀心理包被感(LEV)之提升。
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.
