固体式电吉他虽然可以被各种电子设备转换，但它的声音源于弦的振动，并与弦振动有很强的联系。弦与吉他的耦合改变了它的振动，并可能导致衰减时间的不均匀。本文提出并论证了电吉他音色衰变时间的研究框架。从理论和实验上确定了两种减振机制：弦的本征减振和与吉他琴颈机械耦合引起的减振。电磁拾取器显示不会给管柱提供任何额外的减振。拾取器对弦的平面外极化也显示出更高的敏感性。最后，只要知道吉他琴颈的孤立弦阻尼力和离面电导，就可以准确地预测电吉他音调的衰减时间。这一预测对仪器制造商和制造商有很大的帮助。(C)2014年美国声学学会。
Although it can be transformed by various electronic devices, the sound of the solid body electric guitar originates from, and is strongly linked with, the string vibration. The coupling of the string with the guitar alters its vibration and can lead to decay time inhomogeneities. This paper implements and justifies a framework for the study of decay times of electric guitar tones. Two damping mechanisms are theoretically and experimentally identified: the string intrinsic damping and the damping due to mechanical coupling with the neck of the guitar. The electromagnetic pickup is shown to not provide any additional damping to the string. The pickup is also shown to be far more sensitive to the out-of-plane polarization of the string. Finally, an accurate prediction of the decay time of electric guitar tones is made possible, whose only requirements are the knowledge of the isolated string dampings and the out-of-plane conductance at the neck of the guitar. This prediction can be of great help for instrument makers and manufacturers. (C) 2014 Acoustical Society of America.
