臺灣博碩士論文加值系統

藉由"聲波時域有限差分法", 本論文首次嘗試使用模擬的方法求出"三度
空間音效系統"中, 具有舉足輕重地位的" 與頭部有關之轉移函數 ". 論
文中將數值模擬結果, 與文獻上之量測數據作比較. 一致的趨勢初步驗證
了數值方法的正確性, 並為本論文之假設-" 使用數值模擬較量測方法簡
便"-提供有力之證據. 此外, 論文中亦藉由模擬結果對轉移函數的物理現
象提出解釋, 並提出未來改進數值方法之方向.

By applying the " Finite Difference-Time Domain Method" in
acoustical scattering problem, this thesis tries to calculate
the " Head Related Transfer Function" which plays a critical
role in " 3D Sound System ". This is the first time to obtain
this transfer function by simulation. The numerical results are
compared with the measurement in literature. The similar trend
in both results verifies the correctness of the numerical method
and provides strong support to the assumption that simulation is
simpler than traditional measurements. In addition, the physical
characteristics of the transfer function are interpreted from
the numerical results. Several ways to improve the performance
of this method are also be discussed.
