碩士 === 國立臺灣海洋大學 === 系統工程暨造船學系 === 99 === The objective of this thesis is to establish and analyze the model of architectural acoustic field characteristic, with the program of Ease we can obtain the acoustic field properties and also to compare the simulate value and the experiment value. Finally to construct the standard procedure which include the parameters design with program Ease before construction and after to measurement the real parameters in the sound field. By means of the Ease we can avoid the error from construction or evaluate with the existing sound field before rebuild in order to reduce the cost of manpower and time. In the part of simulate with room acoustic field parameters we use some different kind of room and compare the parameters such as reverberation time(RT), clarity( , ), articulation loss of consonant (Alcons) and rapid speech transmission index (RaSTI), to discuss the accurate of the result and provide some experience to the relate field.
