摘　　要：采用驻波管法对胶合板的吸声性能进行研究,通过对泡桐、杨木、桦木、桉木以及竹胶合板的吸声系数进行测量,探了树种、厚度对胶合板吸声系数的影响。实验结果表明:胶合板成板树种、胶合板厚度对材料的声学性能影响显著,随着厚度的增加其吸声系数有所改善,在一定范围内,树种对胶合板吸声系数影响显著。A standing wave tube method is used to study the sound absorption performance of plywood and the sound absorption coefficients of paulownia plywood,poplar plywood,birch plywood,eucaliptus plywood and bamboo plywood are measured to seek the effect of tree species and thickness of the sound absorption coefficient of plywood,with the experimental result showing that the tree species for plywood and plywood thickness have a noticeable effect on acoustic performance of materials. With the thickness increase,the sound absorption coefficient can improve to certain degree. With a certain scope,tree species have a significant effect on the sound absorption coefficient of plywood.
