基于物理模型的声音合成技术是一种可以精确描述物体发声的方法
其实质是以物体的振动PDE方程为基础来直接合成声音
该方法已逐步成为目前声音合成技术领域内的研究热点.本文从理论上和试验上证明了一个被研究者广为引用的一维基础PDE方程存在的局限性
利用力学理论推导出了新的振动PDE方程
并从理论上和试验上证明了其正确性
从而提出了更具普遍意义的新一维声音合成基础方程
克服了传统方程的缺陷.
Sound synthesis technique based on physical model is a kind of accurate method to describe object's sounds.The method is based on partial differential object's vibration equation of to synthesize sound directly.Presently
the method is becoming an important research field on digital sound synthesis.Under our research
we discover that the PDE cited by many researchers for a long time is extreme limitation
and prove those by theory and experimentation.And then
we derive a new PDE by dynamics elements.Last
we prove that our new PDE is correct.So
a new basic and universal equation has been proposed by the paper for sound synthesis based on physical model.
