研究了钢琴音调衰减率随音调持续时间而降低的原因，包括以下方面：不同振动模式或模式组的不同速率，机械能到声能的非线性转换，用于随后的声辐射的机械能的存储，垂直于和平行于弦桥的弦模式之间的能量传递，几乎精确调谐的弦之间的干涉，以及在从初始同相条件到后来的异相条件的过渡期间从多串源到桥的能量传递速率的变化。最后两个密切相关的因素被发现在大多数情况下控制率的变化。
Causes for the decrease in rate of piano tone decay with time of tone duration were investigated, including the following: different rates for different vibration modes or groups of modes, nonlinear transformation of mechanical energy to acoustical energy, storage of mechanical energy for subsequent acoustical radiation, transfer of energy between string modes perpendicular and parallel to the bridge, interference among strings that are almost exactly in tune, and change in rate of energy transfer from the multiple‐string source to the bridge during the transition from an initial in‐phase condition to a later out‐of‐phase condition. The last two closely related factors were found to control the rate change in most cases.
