【摘要】 在理论分析的基础上阐明了钢琴声音频谱中的一些非谐和分音(“伪”分音)产生的原因,指出这些非谐和分音是由弦振动的固有谐音通过非线性叠加产生的。文中给出了实验数据,表明理论分析与实验相符合。更多还原

【Abstract】 This article explains the existence of inharmonic partials (phantom partials) in piano sound spectrum. It is proved theoretically that these inharmonic partials are produced by the nonlinear combination of harmonics. Experimental data show that it is consistent with theoretical analysis.更多还原
