中文摘要 | 本研究調查了22個會廳中建築參數與六個室內音質指標之室平均值換統計關係,並根據文獻開發了數十個量化之建築參數,及其數據量度的方法。 研究結果除印證了文獻中許多建築參數與音質指標的統計關係外,並歸納出其它統計關係,譬如測點水平旋轉角之平均值與清晰指數(C80)之反向直線關係。本研究所建立之線性回歸模型,可有效的解釋(55至97%)6個音質指標室平均值的變異,部份模型並包含了對擴散音場理論計算值修正。當樣本僅包含具樓臺之中大型集會廳時,與樓臺深度相關之建築參可提高如相對音壓級(G)等音效指標的回歸模型之解釋能力。 本研究肯定了許多集會廳音效的設計理念,所分析出的重要建築參數可作為更深入研究之基礎,而多元回歸公式可在設計之初期階段來預估音質指標的數值。 |
英文摘要 | Architectural parameters were used to estimate the room average values of six room acoustical measures based on data taken in twenty halls. A comprehensive method of quantifying various architectural characteristics of rooms was developed to define a large number of architectural parameters. The relationships among architectural parameters and the hall average of acoustical measures generally agreed with the results of previous studies by Gade. Other statistical relations were identified such as the negative correlation coefficient between acoustical measure Clarity Index (C80) and architectural parameter Average Horizontal Angle of Receiver. The regression models reasonably explained much of the variance (55%~97%) of the acoustical measures. Some models were derived to adjust calculated estimates based on diffuse sound field theory. Architectural parameters such as the ones associated the shape of the under-balcony spaces were found to increase model accuracy when only the rooms with balconies were included. This study revealed the major architectural parameters which have strong relations with individual acoustical measures forming the basis for a more quantitative studies. The results of this study provide designers the information to predict acoustical measures at very early stages of the design process. |
