The objective of this paper is to investigate the rattan materials and test the sound absorption coefficients of rattan cane with standing wave tube. We discuss the relationship between the sound absorption performance and sample thickness, and analyze the influence of epidermis and nodes as factors on the sound coefficients. The results show that rattan cane material has good absorption properties, the sound coefficients increase with the increasing frequency; the coefficients increase with the adding thickness; epidermis and nodes improve the absorption properties. As a whole, rattan cane material has good absorption properties, and can be provided as a basis for future usage
