摘要

评估树木和原木的内在木材质量,如弹性模量和内部衰变,可能具有挑战性。然而,声学技术已经研究了一种可能的解决方案。本文回顾了现有的无损声学方法评估木材质量的文献,包括树木和原木。本文进一步综述了非破坏性声学方法评价的造林措施(如疏伐和修剪)对木材质量的影响。我们记录了一些应用无损声学方法对树木和原木木材质量的好处。树木的声速(VT)或传播波的对数(VL)和木材密度可以用来确定动态弹性模量(MOEd)。据报道,薄变对VT/VL和MOEd有负面影响。声学层析成像方法同样被发现在检测直立树木和原木的木材腐烂的位置和程度方面具有良好的准确性。

Non-destructive acoustic assessment of wood quality in trees and logs and the effects of silvicultural treatments: a review
ABSTRACT Assessing intrinsic wood qualities such as modulus of elasticity and internal decay in trees and logs can be challenging. However, acoustic technologies have been investigated for a possible solution. This paper reviews available literature on non-destructive acoustic methods for assessing wood quality, both in tree and log form. The paper further reviews the effects of silvicultural practices (such as thinning and pruning) on wood quality assessed by non-destructive acoustic methods. We documented some of the benefits of application of non-destructive acoustic methods on wood quality of trees and logs. The acoustic velocity of a tree (VT) or log (VL) of the propagated waves and wood density can be used to determine the Dynamic Modulus of Elasticity (MOEd). Thinning was reported to affect VT/VL and MOEd negatively. Acoustic tomography methods were equally found to have good accuracy in detecting the location and extent of wood decay in standing trees and logs.
