An experimental investigation on the coupling between the fingerboard and the top plate of a classical guitar at low frequencies is presented. The study was carried out using a finished top plate under fixed boundary conditions and a commercial guitar. Radiated sound power was determined in one-third octave bands up to the band of 1 kHz based on measurements of sound intensity. The results provide evidence that the way in which the fingerboard and top plate are coupled is not a relevant factor in the radiated acoustic power of the classical guitar in the studied frequency range.
本文对低频下古典吉他指板与面板之间的耦合进行了实验研究。研究采用固定边界条件下的成品面板和一把商业吉他进行。根据声强测量，在 1 kHz 频段内的 1/3 倍频程频段内确定了声功率。结果表明，在研究的频率范围内，指板与面板的连接方式不是古典吉他辐射声功率的一个相关因素。
