Abstract: The formation of complex patterns in physical or biological systems is often caused by the interaction of many low (Kolmogorov) complexity systems, leading to emergent collective effects. In this contribution, we demonstrate how complex processing of acoustic signals by the peripheral auditory system may emerge from the interaction of a number of Hopf bifurcators, which serve as the fundamental low-complexity mechanisms in a biophysical cochlea model. This analysis requires that adequate notions of complexity for acoustical signals and for the involved processing mechanisms are developed.
