英语翻译
Perhaps surprisingly,the overtones of struck piano strings do not adhere to a strict harmonic frequency relationship because of the percussive nature of their resonance (compared to a continually stimulated stringed instrument),and tend to be slightly higher than the maths would predict.This phenomenon is particularly obvious in the higher registers of smaller pianos where the strings are stiffer than normal due to their required strength and shortness,and results in a less pure and sonorous sound quality.
With the dampers lifted,a piano will resonate for over 10 seconds in the middle registers and over 40 seconds in the bass strings,although the balance of decay times is very dependent on the construction.
The top C may last around 3 seconds and the same spread of decay times is apparent within the harmonic series of a single note,with the fundamental or first partial lasting far longer than the upper harmonics.The dynamic range of a piano,measured at the rather distant reach of 10 meters,varies between about 85dBC and 70dBC for the loudest playing (the upper notes being weaker than the bass notes).At the quiet end of the scale,bass notes rest around 50dBC,with mid and upper notes falling to 37dBC.

也许令人惊讶的是色彩,钢琴弦不支持一个厉害的冲击 自然频率的系统,因为共振(而不断刺激弦乐器),往往是略高于数学预测.这种现象成为更明显的寄存器的小钢琴的字符全是硬度比正常由于他们需要力量和呼吸急促,和结果在一个更少的纯和响亮的声音质量.
阻尼器的解除,钢琴将超过10秒的共鸣在中间寄存器和低音弦在40秒,虽然衰变时间的平衡是非常依赖于施工.
