摘要

在这项研究中，我使用木屑颗粒作为一种环保吸声材料。研究目的是分析木屑颗粒填充高度对吸声性能的影响。这是使用两种不同长度的木屑颗粒完成的（A组：1.5–3厘米，B组：小于1.5厘米）。随着木屑颗粒填充高度的增加，最佳吸声率向低频率方向移动。B组木屑颗粒的吸声性能优于A组。填充到7cm高度的A组在864Hz下的最佳吸声系数为0.722。另一方面，在862 Hz下，B组填充到7厘米高的声音为0.764，比a组高5.82%。虽然木屑颗粒被用作环保燃料，但本研究的结果表明，使用木屑颗粒作为环保吸声材料的可能性。

Experimental Investigation of the Sound Absorption Capability of Wood Pellets as an Eco-Friendly Material

In this study, I used wood pellets as an eco-friendly sound-absorbing material. The aim of the research was to analyze the effect of the filling height of wood pellets on sound absorption. This was done using two types of wood pellets of different lengths (A group: 1.5–3 cm, B group: less than 1.5 cm). With increasing filling height of the wood pellets, the optimum sound absorption shifted towards a lower frequency. The group B wood pellets had better sound absorption capacity than the group A ones. The optimum sound absorption coefficient of group A filled to a height of 7 cm was 0.722 at 864 Hz. On the other hand, that of group B filled to a height of 7 cm was 0.764 at 862 Hz, 5.82% higher than that of group A. While wood pellets are used as an eco-friendly fuel, the results of this study suggest the possibility of using wood pellets as an eco-friendly sound-absorbing material.

期刊介绍： The Journal of the Korean Wood Science and Technology (JKWST) launched in 1973 as an official publication of the Korean Society of Wood Science and Technology has been served as a core of knowledges on wood science and technology. The Journal acts as a medium for the exchange of research in the area of science and technology related to wood, and publishes results on the biology, chemistry, physics and technology of wood and wood-based products. Research results about applied sciences of wood-based materials are also welcome. The Journal is published bimonthly, and printing six issues per year. Supplemental or special issues are published occasionally. The abbreviated and official title of the journal is ''J. Korean Wood Sci. Technol.''. All submitted manuscripts written in Korean or English are peer-reviewed by more than two reviewers. The title, abstract, acknowledgement, references, and captions of figures and tables should be provided in English for all submitted manuscripts.
