Abstract:
1. A method for improving the acoustic characteristics of resonant wood for musical instruments, the method comprising: exposing the resonant wood, at a temperature of 18 to 26° C. and a relative humidity of 60 to 80% for a treatment period of 6 to 15 weeks, to the action of a wood decomposing fungus in the form of Asco- und Basidiomycetes selected from the family of Leotiaceae, Polyporaceae, Schizophyllaceae, Tricholomataceae and Xylariaceae, the selected wood decomposing fungus and the treatment period providing that the ratio of the velocity of sound of the wood to the bulk density of the wood is increased while maintaining minimum strength values of the resonant wood.
