Résumé

The discussion that we suggest here relates directly with multiple sessions from Instrument making to measurement techniques. To discuss about the Acoustics of musical instruments, we explain the mathematical form of the acoustic function of the instruments. If we consider the acoustics of the musical instruments as a mathematical formula, we can study it as a 4-port module with an input multiplied in the module function and the output. The mathematical function of this acoustical body of the instrument is a nonlinear Multi order complex function. The produced sound is the application of the function to the input or the mechanical vibrations of the strings. De-correlating and de-modulating the Complex sound of the musical instruments and studying the decomposed sound is the first milestone of understanding the behavior of Acoustical Instruments. The strings instrument makers who have the golden ears too, use their very sharp sensitive hearing capabilities to feel the de-correlation, which is why this domain of acoustics remains as an art reserved to some very few genius artisans. To open scientifically the gates of musical acoustic, our S7B module treats the complex results of the acoustical instruments.
