Molding the asymmetry of localized frequency-locking waves by a generalized forcing and implications to the inner ear
Abstract
Frequency locking to an external forcing frequency is a {well} known phenomenon. In the auditory system, it results in a localized traveling wave, the shape of which is essential for efficient discrimination between incoming frequencies. An amplitude equation approach is used to show that the shape of the localized traveling wave depends crucially on the relative strength of additive vs. parametric forcing components; the stronger the parametric forcing the more asymmetric the response profile and the sharper the traveling-wave front. The analysis captures the empirically observed regions of linear and nonlinear responses and highlights the significance of parametric forcing mechanisms in shaping the resonant response in the inner ear.
