【摘要】：近年来,国内研究者采用主观评价的方式对钢琴音质的研究为数不多,且多集中在琴弦振动方面,本文在已有研究基础上,通过对不同钢琴采样的录制、比较与分析,用主观评价的方法研究了钢琴音板震动的声音信号,结合信号处理,发现了能影响钢琴音质的几个要素:(1)高次谐波(18次以上)对音质影响不大;(2)高次杂波对音质影响不大;(3)低于理论基频的峰对音质有一定的影响;(4)对1~18次谐波的声音均衡调整对音质有明显影响。
[Abstract]:In recent years, domestic researchers using subjective evaluation methods to study piano sound of the few, and more concentrated in the string vibration, this paper based on the existing research, through the sampling of different piano recordings, comparison and analysis, the sound signal of steel plate vibration sound is studied by the method of subjective evaluation, combined with the signal processing, found several elements can affect the quality of a piano: (1) harmonics (18 times) has little effect on sound quality; (2) high clutter has little effect on quality; (3) lower than the fundamental frequency peak have a certain impact on the sound quality; (4) to adjust the 1~18 harmonic sound equalization have obvious influence on the sound quality.
