Synchronization of organ pipes
We investigate synchronization of coupled organ pipes. Synchronization and
reflection in the organ lead to undesired weakening of the sound in special
cases. Recent experiments have shown that sound interaction is highly complex
and nonlinear, however, we show that two delay-coupled Van-der-Pol oscillators
appear to be a good model for the occurring dynamical phenomena. Here the
coupling is realized as distance-dependent, or time-delayed, equivalently.
Analytically, we investigate the synchronization frequency and bifurcation
scenarios which occur at the boundaries of the Arnold tongues. We successfully
compare our results to experimental data
