Abstract
Evaluation of the acoustic properties of objects using the obtained results as an informative parameter in determining the physical and mechanical characteristics of the material, as well as in the field of non-destructive testing, is widely used in modern science and technology. In the present paper the possibility of using this approach is considered in relation to the woodworking industry in order to estimate the characteristics of sawn timber modified by the ultrasonic method. The results of previous studies have shown the effectiveness of this technology for increasing the surface density and hardness of wood, therefore one of the urgent tasks is to find criteria that allow evaluating the achieved modification parameters, as well as optimizing the settings of the corresponding technological equipment.In this paper the research results of the acoustic properties of ultrasonic modified aspen wood (Populus Tremula) are represented and their applicability as a criterion for estimating the degree of modification for industrial wood blanks is revealed.
