摘要

本研究探讨了花生壳作为绿色吸声材料的应用前景。分别在30mm、60mm和90mm高度的阻抗管中填充花生壳，测定吸声系数。吸声能力随填充物高度的增加而增加，30mm、60mm和90mm填充物的降噪系数分别为0.23、0.43和0.54。此外，对于大于2000 Hz的声音，花生壳在60和90 mm高度的平均吸声系数为0.9。综上所述，花生壳具有与竹、剑麻、黄麻和羊毛相当或更好的吸声性能，本研究表明花生壳可能是一种有用的环保吸声材料。

Peanut Shells as an Environmentally Beneficial Sound-Absorbing Material

This study investigated the prospect of using peanut shells as an alternative and green sound-absorbing material. The sound-absorption coefficients were determined after filling impedance tubes of 30, 60, and 90 mm in height with peanut shells. The sound-absorption ability increased as the filling height increased, showing noise reduction coefficient (NRCs) of 0.23, 0.43, and 0.54 for the 30-, 60-, and 90-mm heights, respectively. In addition, for sounds greater than 2,000 Hz, the average sound-absorption coefficient of peanut shells in the 60and 90-mm heights was 0.9. In summary, peanut shells were found to have good sound-absorption properties comparable to or better than those of bamboo, sisal, jute, and wool, and this research suggests that peanut shells may be useful as an environmentally 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.
