목재공학, 07/2011, Volume: 39, Issue: 4Journal Article
국산 산공재 중 구조적 특징이 목재흡음에 적합하다고 생각되는 백합나무 목재 횡단면의 흡음성능과 기체투과성의 방사방향 변동과 폭쇄처리 영향을 관찰하고자 무처리와 폭쇄처리 목재원반에서 방사방향위치가 다른 원형시험편을 재취하여 전달함수법과 CEP (capillary flow porometry)법으로 흡음률과 기체투과성을 각각 측정, 비교하였다. 측정주파수범위에서 폭쇄처리 횡단면의 흡음률이 무처리재보다 높은 흡음성능을 나타내었으며 횡단면에서는 대경 도관이 다수 존재하여 다공질형흡음에 유용한 연속된 모세관이 다량 존재하는 사실을 확인할 수 있었다. 방사방향으로는 심재부위에서 채취한 시험편보다 변재부위에서 채취한 시험편의 흡음계수가 높은 흡음률을 나타내었으며, 기체투과성도 변재부위가 심재부위보다 높은 수치를 나타내었다. Radial variation of sound absorption capability and air permeability of yellow poplar (Liriodendron tulipifera) wood in cross sectional surface and effect of steam explosion treatment were estimated by the two microphone transfer function method and the capillary flow porometry, respectively. The sound absorption coefficients of steam explosion treated wood was higher than those of control wood and these values increased with frequency. Abundant and big vessel may behave as sound absorbing pore observed on the cross sectional surface of yellow poplar wood. The sound absorption coefficients and air permeability of sapwood were higher than those of heartwood for Liriodendron tulipifera.
