  • The Influence of Outer Hair Cells on Tectorial Membrane Waves Reviewed

    The cochlea, a vital structure for hearing, comprising the scala media, scala tympani, and scala vestibuli, separated by Reissner’s and basilar membranes. The scala media houses the organ of Corti, containing inner and outer hair cells (IHCs and OHCs). Extensive research has explored OHCs, focusing on their mechanical properties and role in cochlear mechanics. This study investigates the impact of OHCs on two types of tectorial membrane (TM) slow waves, termed TM wave 1 and TM wave 2, using modal analysis. The research utilizes a model incorporating the basilar membrane, TM, and OHCs. The study explores how OHCs influence the propagation characteristics of these waves. Results demonstrate that OHCs affect TM wave 1 minimally, with distinctions becoming negligible at higher frequencies. In contrast, OHCs significantly influence TM wave 2, especially in the high-frequency range. The study further explores the frequency-dependent phase and attenuation constants of these waves, revealing substantial effects of OHCs on TM wave 2 across different frequencies and TM widths.

    We investigated the dispersion characteristics of the propagation modes that progress on the tectorial membrane (TM). Recent studies have uncovered complex TM behavior and a possibility that TM might play an important role in the hearing system. An interaction between the TM and the fluid induces propagation modes, which are called TM modes. We found that there are several kinds of TM modes and analyzed the direction of the displacement of the TM that is caused by each mode. We also investigated the structural dependency of the angular wavenumber of each mode.

    In this paper we propose a new type of comb-line filter which consists of a couple of meander-shaped quarter-wavelength microstrip resonators. We investigate the filtering characteristics through FD-TD simulations. Furthermore, we design the filter and discuss its filtering characteristics through experiments as well as numerical simulations. It is found that this filter realizes a considerable reduction in the size of structure and sharp bandpass characteristics with multiple attenuation poles around the passband.
