How can the autocorrelation coefficient be determined by the instrument maker on the raw wood before starting to build a table?
top The mean sensitivity test and the determination of the autocorrelation coefficient do not have a direct importance for the musical instrument dating, but they can be of very interest for the instrument making scholars as they would be helped in the evaluation of the wood choice made by the ancient maker of the instrument they are investigating. Furthermore they can be of valuable help to the present maker for properly choosing the wood selection he will transform into that part of the instrument which has so great importance for the final acoustical yield. Practically the instrument maker before starting to operate on a wood selection of red spruce for the table building can determine its autocorrelation coefficient by cutting from it a few millimeter strip that will show transversally the tree-rings as a core so that their widths will be measured very easily and accurately, and with the help of Synchro Search the values matched against a master chronology. The autocorrelation coef
