解析室內聲學通常是使用迴響時間與室內音壓級來判別聲音特性，上述兩種解析法是屬於總量與平均值計算法，卻無法取得聲音更細部的特性。根據文獻中脈衝響應圖可解析聲音細部的特性並利用圖形法解析聲音更細部特性。

本研究參照ISO 3382現場量測法，將現場不同空間類型分析與比較對脈衝響應圖之影響。文獻提出的圖形解析法與極端環境下脈衝響應圖分布情況作為分析與比較現場量測的脈衝響應圖。本研究提出十種解析脈衝響應圖的評估法，實際運用於音樂廳空間類型驗證十種評估法對室內聲場中聲音細部特性的解析。

本研究具體成果如下：
(一)設計運用建議:
本研究將空間類型分為(1)空間形狀(2)空間容積(3)空間室表面積三個部分，探討不同空間類型並比較各測點對脈衝響應圖的影響:
(1)空間形狀，將同一空間容積與室表面積相同情況下，研究結果改變天花板造型時，室內空間觀眾席中後方時間延遲相差為中央位置6％及後方13％，發現有較為顯著的變化。
(2)空間容積，將同一空間形狀與室表面積相同情況下，研究結果比較小容積空間時，發現時間延遲相差比矩形與扇形空間有較顯著的變化。
(二)實際案例運用:
本研究驗證音樂廳空間中，透過本研究提出的十種解析室內聲場的方法，針對室內聲場於各測點的脈衝響應圖分布情況，找出室內聲音缺失，作為往後建議與改善現況室內聲場的裝修材料。

因此，本研究提出的脈衝響應圖是可依研究指出的十種評估表進行解析室內聲場，並提出研擬與對策來改善室內聲場聲音的缺失。

Parsing the room acoustics are usually reverberation time and indoor sound pressure level to distinguish the sound characteristics of the two analytical method are the total average calculation method, but unable to obtain more detail sound characteristics. Pulse response graph based on literature resolvable sound detail the characteristics and features graphical method parse sound more detail.

This study is based on the ISO 3382 field measurement method, the on-site analysis of a different type of space and compare Figure impulse response of. Graphical analytical method proposed by the literature and impulse response in Fig distribution extreme environments as the impulse response analysis and comparison of field measurements in Fig. This study proposes a ten kinds of analytic impulse response graph Assessment Act, and the practical application of the concert hall space type validation the ten evaluation method of the detailed characteristics of the indoor sound field sound analytical.

The concrete results of this study are as follows:
(A) the use of design recommendations:
In this study, the type of space divided into (1) the shape of space (2) space volume (3) Space Room surface area of the three parts to explore a different type of space and compare each measuring point of the impulse response graph:
(1) The shape of the space, the surface area of the same volume of space with room under the same circumstances, the results change ceiling moldings, the indoor space auditorium in the rear time delay difference for the central position of 6% and rear 13%, more significant changes.
(2) space volume, shape chamber surface area of the same space in the same case, the the results relatively small volume of space, the time delay difference between the more significant changes than rectangular and fan-shaped space.

(B) the use of actual cases:
This study tested the concert hall space, ten parse indoor sound field through the present study, the distribution of response graph for indoor sound field at the pulse points, find out the lack of indoor sound as subsequent recommendations to improve the situationindoor decoration materials of the sound field.
