Due to various property changes such as low moisture sorption, reduced reaction to climatic variability or improved elastic properties different thermal treatment processes also offer its application in the field of instrument making for the treatment of tonewood. In recent years, the process has become more important in the search for tropical wood alternatives, but is also recommended for use in restoration for artificial wood aging (Pfriem et al., 2008, Krüger et al., 2020). In previous studies investigations on property changes due to thermal treatment were presented, in which only changes in temperature or time were made but always using a single process. Therefore, in this study, the influence of two different processes but at the same treatment temperature, a thermo-vacuum process and a process that takes place in a reduced-oxygen atmosphere on various property changes of spruce resonance wood was investigated.
