| An ear is one of the smallest and the most important organs in a human body. Hearing loss becomes a significant problem for modern societies. Therefore, a non-linear model of the human middle ear is used to study effectiveness of a middle era implant. Special care is focused on the effect of floating mass transducer fixation on the ear system dynamics and sound transfer to the inner ear. A transducer fixation is realized by means of a coupler. Its characteristic plays the key role in stapes excitation. A numerical analysis for two variants of damping properties is performed, representing the intact and pathological ear stimulated by a low and strong external signal. A stiffness characteristic of the coupler can shift a main resonance region of the middle ear structure and cause polyharmonic and even chaotic motion of the stapes and the transducer. As a result, the conditions of regular and irregular vibrations of the stapes, near the primary resonance, are defined. Finally, practical remarks about how to avoid polyharmonic and irregular oscillations are proposed. |
