摘要
从实验上研究了钢琴的不谐和系数B对主观听感的影响。通过对钢琴的原始录音进行分析,并对分析数据进行处理,合成出几个不同B值的钢琴音。合成音与原始录音的听感比较实验结果表明,B值对低音键的音质影响较为明显,过高或零的B值都会产生较差的音质。但在现有生产技术条件所给出的最低(B=0.00005)极限范围之上,减少B值可使钢琴的低音键在主观听感上较为厚实。
The e ff ect of inharmony coefficient B on piano tone quality is researched in this pape r.The original piano tones are analyzed with computer.Analysed data are proces sed and new piano tones with different B values are synthesized.In the listeni ng test,the synthesized and original piano tones are compared.The result of th e test shows that inharmony has greater effect on the bass section of a piano. The tone with large or zero B value is unpleasant to ear.With B above0.00 005,which is the extremely low B value according to the contemporary technol ogy,the less inharmonic bass tone sounds thicker.
