Abstract:	此論文利用ANSYS軟體模擬分析方法，以模型Jupiter str-1700高音小號之聲場分析，再利用直管與錐管的聲場理論去進行確認所分析出的數據正確與否，之後進行實體樂器的實驗，並轉換成可以比對的數據後，以判別模擬數據是否可以得出與實際樂器之音高，並確定此研究方法可行性。由實際數據比對，本文中所用的模擬方法可以得到與實驗相似趨勢的曲線，最後示範使用此方法對小號的設計進行修正，以達到更加的音準與音質。 The thesis utilizes the finite element software, ANSYS, to simulate the sound field of a musical instrument. The trumpet (model Jupiter STR-1700) is taken as the physical system for the acoustic analysis. Data from theoretical acoustic analysis and ANSYS of a taper tube are compared to verify the finite element software. Then, the actual trumpet is analyzed by ANSYS and the experiments are also conducted for comparison to confirm the accuracy of simulation results. From the data, these two methods can provide similar trends of the acoustic characteristics of the system. A supposition can be made for the correction of the ANSYS model. Furthermore, the analysis is used for the design of the instrument.
