In this chapter, the focus is on the viscoelastic characteristics of wood expressed by the damping coefficients in the acoustic frequency range. The effect of various factors such as the moisture content, temperature, thermal and chemical treatments, ageing on the internal friction in wood in the acoustic frequency range will be described.

摘要

In this chapter, the focus is on the viscoelastic characteristics of wood expressed by the damping coefficients in the acoustic frequency range. The effect of various factors such as the moisture content, temperature, thermal and chemical treatments, ageing on the internal friction in wood in the acoustic frequency range will be described.
