Abstract:

We use Independent Component Analysis, an entropy based method to study self-sustained sound generated by organ pipe and recorded in an anechoic chamber. We recover a simple analogical model that can be ascribed to the same types of Woodhouse, Yoshikawa models [3,11]. Our model is able to reproduce in the listening the generated sound. Then we use self-sustained oscillators as a source for linear organ pipe models and we observe that the real signals can be reproduced only considering nonlinear interaction between the different constituents of an organ pipe.
