COCHLEAR TRANSDUCTION–THEORETICAL ASPECTS

摘要: Publisher Summary When the stapes (the stirrup ossicle) is set into oscillation, a traveling wave arises along length of basilar membrane (BM). Near stapes, BM very stiff and hence, travels with large velocity propagation. On progressing further on in cochlea, becomes more compliant propagates slower slower. Meanwhile, energy contained one period (or wavelength) concentrated henceforth, amplitude increases. Eventually, region reached where almost comes to standstill. The goes through maximum energy, which until this point has been carried by fluid, dissipated over short stretch BM. Virtually, nothing that left, means directly beyond peak attenuated rapidly. location at occurs depends upon frequency: Low frequencies have their apical part cochlea high near base.
