The human hearing organ is a signal processor par excellence. Its amazing abilities are often described in terms of psycho-acoustic models. However, in this chapter the focus is laid on the physical background, particularly on the physics of the peripheral hearing organ. The peripheral system can be looked at as a signal conditioner and preprocessor which stimulates the central nervous system. It comprises acoustic, mechanic, hydro-acoustic, and electric components which, in total, realize a sensitive receiver and high-resolution spectral analyzer. For daily life it is extremely important that the hearing organ can also work under adverse conditions. This includes the need for general robustness and low sensitivity with respect to varying external and internal working conditions. In the hearing organ several strategies are found which noticeably differ from technical solutions.
