運用一般活塞式小號所達成之再造維也納式小號樂音

Abstract

截至目前為止，本研究利用有限元素分析法建立了一把轉閥小號和一把活塞 小號的物理模型。模型中，兩把小號的特徵頻率和頻率響應(即轉移函數)已被求 出；而可用以在活塞小號上製造出維也納式小號音色的壓力源也已於頻域上解 出，並模擬出初步的輸出音訊。

My research, thus far, consists of building two kinds of models of rigid-wall trumpets by the finite element method. My research demonstrates feasibility by solving the eigenfrequencies, the impulse response (or the transfer function) and the modulated input source that is supposed to be capable of reproducing a Viennese style trumpet sound via a regular piston trumpet. In addition, the objective of this research has been achieved to some extent such that future improvement is possible.
