Abstract
New method and technical solutions for nondestructive express diagnostics and targeted selection of spruce wood with unique dendro-acoustic properties aged in buildings are presented. Flow charts of equipment and ways of its application to identify resonant properties of wood in different parts of a building, including the walls made of round timbers, ceiling and floor boards are given. The proposed ways of wood quality diagnostics in buildings has its advantages over conventional methods.
Highlights
It is known that after keeping wood in natural environment for a long time it undergoes irreversible processes resulting in a change in its organic composition: lignin fraction increases and the content of hemicellulose fraction, especially pentosane, decreases
Musical instruments produced from old timber are capable of producing more stable sound spectra even in changing external environment conditions [1]
