摘要
本文以大阮为主，兼顾中小阮给出阮的声学特性。阮的面板、背板与琴体内空腔和声孔组成耦合振动系统，在低频出现两个明显的共振。阮面板的振动模态与圆板振动相比较在频率不高时存在一定的规律。文中给出大阮的声频谱和琴体振动发声的影响。
Different kinds of Ruan are traditional plucked string musical instruments in China. The acoustical properties of Ruan are presented in this paper. Two resonances occur at low frequencies due to the coupling vibrations of top plate, back plate, enclosed air and soundholes. The vibrational modes of Ruan body have been measured and analysed as compared with the vibration of a circular plate. Sound spetra one meter in front of a tenor Ruan are given and the influences of body vibrations are discussed.
