钢琴弦槌的品质对钢琴的音质有很重要的影响,其弹性、质量、杆长等因素的变化都会引起音质的变化。首先建立模拟钢琴发音的实验模型,通过改变弦槌的各种参数,分别进行击弦实验,对采集到的乐音信号进行处理。通过时域和频域的对比,总结出各种参数变化对钢琴音质产生的具体影响,并对实际钢琴中参数的选择提出了参考意见。 Piano hammer quality piano has a very important impact on the sound quality, length and other factors will lead to changes in the quality of sound. First, an experimental model of simulated piano pronunciation is established. By changing various parameters of the hammer, the strings are tested respectively and the collected musical signals are processed. Through the comparison of the time domain and the frequency domain, the concrete influence of various parameters on the piano sound quality is summarized, and the reference suggestions are given for the choice of parameters in the actual piano.
