ABSTRACT
The chapter focuses on otoacoustic emissions (OAEs) decomposition based on the cochlear model and time–frequency analysis. As OAEs origin is not explained well, we present one from many concepts for the more in-depth inspection of cochlear mechanisms which relate to the acoustical signal registered in a probe inserted to the external ear canal. The basic models of cochlear generators will be discussed. On the other side, the hearing apparatus will be treated as a black box which is observed utilizing transiently evoked OAE registration in various modalities of stimulation. As the signal processing tool for analysis, the Wigner–Ville Distribution (WVD) will be emphasized in detail. The WVD could be used as a very convenient stage in time-varying filtering which in turn gives a flexible tool for decomposition of the signal into a set of primitives. It will be later discussion on the question what an impact of this method for could be explaining of OAE origin.
