Figure 4: Model curve according to the studies of Ren et al., Batta, and Borkó. The model describes the DPOAE change in the simultaneous presence of efferent neurotransmitters and the mechanically induced increase in OHC lateral wall stiffness. Continuous line shows the curve calculated by the model (see (1)). The dotted line shows increase of DPOAE in the presence of efferent neurotransmitters (first part of (1)). Dashed line indicates decrease of DPOAE in the presence of the mechanically induced increase in stiffness (second part of (1)).
