动态乐音谐波调制的听感谐和性分析

Harmony analysis of harmonic modulated music signals

使用正弦加剩余噪声模型对不同乐器的乐音信号进行动态谐波调制,通过主观评价实验对不同调制模式下乐音的谐和感、粗糙感、自然感、尖锐感四项听感指标进行对比打分。结果表明,谐波调制所带来的谐和相关听感的影响以及合奏的协和感变化,在不同音色类型中具有一致性,谐和听感结果与调制方式有关。

The sinusoidal plus residual noise model is used to modulate harmonic components of dynamic music signals of different instruments.The subjective evaluation experiment is carried out to compare the auditory sensation indicators of consonance,roughness,naturalness and sharpness with different modulation modes.The results show that the effect of harmonic modulation on the sense of consonance is consistent in different timbre types,and the sense of consonance is related to the mode of harmonic modulation.
