摘要

本研究考察了赤松球果作为一种具有吸声性能的环保材料的实用性。制备了宽0.8–1.2厘米、长3.5–4.5厘米的松花粉锥样品。用松花粉锥填充阻抗管至6、8、10或12cm的高度后，研究了松花粉锥的吸声系数。厚度为6cm的样品的峰值吸声频率达到1512Hz；然而，在厚度为12cm的样品中，这一值偏移到了740Hz。因此，随着材料厚度的增加，松花粉锥在低频下的吸声性能有所改善。根据KS F 3503（韩国标准协会），松花粉锥的吸声等级在0.3至0.5M之间，具体取决于松花粉锥材料的厚度。总之，松花粉锥表现出良好的吸声性能。因此，它们可以被认为是一种对环境友好的吸声材料。

Use of Pine (Pinus densiflora) Pollen Cones as an Environmentally Friendly Sound-Absorbing Material

This study examined the utility of pine (Pinus densiflora) pollen cones as an environmentally friendly material with sound-absorbing properties. Pine pollen cone samples with widths of 0.8–1.2 cm and lengths of 3.5–4.5 cm were prepared. After filling impedance tubes to heights of 6, 8, 10, or 12 cm with the pine pollen cones, the sound absorption coefficient of the pine pollen cones was investigated. The peak sound absorption frequency of the samples with a thickness of 6 cm was reached at 1,512 Hz; however, this value shifted to 740 Hz in samples with a thickness of 12 cm. Therefore, the sound-absorbing performance of pine pollen cones at low frequencies improved as the material thickness increased. According to KS F 3503 (Korean Standards Association), the sound absorption grade of pine pollen cones ranges from 0.3 to 0.5 M, depending on the material thickness of the pine pollen cones. In conclusion, the pine pollen cones demonstrated good sound absorption properties. They, thus, may be considered 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.
