【摘要】：近年來(lái),國(guó)內(nèi)研究者采用主觀評(píng)價(jià)的方式對(duì)鋼琴音質(zhì)的研究為數(shù)不多,且多集中在琴弦振動(dòng)方面,本文在已有研究基礎(chǔ)上,通過(guò)對(duì)不同鋼琴采樣的錄制、比較與分析,用主觀評(píng)價(jià)的方法研究了鋼琴音板震動(dòng)的聲音信號(hào),結(jié)合信號(hào)處理,發(fā)現(xiàn)了能影響鋼琴音質(zhì)的幾個(gè)要素:(1)高次諧波(18次以上)對(duì)音質(zhì)影響不大;(2)高次雜波對(duì)音質(zhì)影響不大;(3)低于理論基頻的峰對(duì)音質(zhì)有一定的影響;(4)對(duì)1~18次諧波的聲音均衡調(diào)整對(duì)音質(zhì)有明顯影響。
[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.
