Synchronization in coupled organ pipes
We investigate synchronization in coupled organ pipes. Synchronization and reflection in the organ lead in special cases to undesired weakening of the sound. Experiments show that sound interaction is highly complex and nonlinear. As a model we consider two delay-coupled Van-der-Pol oscillators with distance-dependent coupling. Analytically, we investigated phenomena as synchronization frequency and bifurcation scenarios which occur at the boundaries of the Arnold tongues. We successfully compare our results to experimental data.
