Art Connection In the human ear, sound waves cause the stapes to press against the oval window. Vibrations travel up the fluid-filled interior of the cochlea. The basilar membrane that lines the cochlea gets continuously thinner toward the apex of the cochlea.

Basilar membrane

Basilar membrane - Infogalactic: the planetary knowledge core Structure. The basilar membrane is a pseudo-resonant structure that, like strings on an instrument, varies in width and stiffness. The "string" of the basilar membrane is not a set of parallel strings, as in a guitar, but a long structure that has different properties (width, stiffness, mass, damping, and the dimensions of the ducts that it couples to) at different points along its length.

en.wikipedia.org › wiki › Basilar_membraneBasilar membrane - Wikipedia The basilar membrane is a stiff structural element within the cochlea of the inner ear which separates two liquid-filled tubes that run along the coil of the cochlea, the scala media and the scala tympani. The basilar membrane moves up and down in response to incoming sound waves, which are converted to traveling waves on the basilar membrane.

› basilar-membraneBasilar Membrane - an overview | ScienceDirect Topics The basilar membrane is a resonant structure varying systematically in width and stiffness. It is wider (0.42–0.65 mm) and more flaccid at the cochlear apex than at the base (0.08–0.16 mm). When a sound wave is transmitted to the fluid of the inner ear, the basilar membrane is set in motion.

Timing of the reticular lamina and basilar membrane vibration ...

Critical band - Wikipedia The basilar membrane widens as it progresses from base to apex. Therefore, the base (the thinnest part) has a greater stiffness than the apex. This means that the amplitude of a sound wave travelling through the basilar membrane varies as it travels through the cochlea. When a vibration is carried through the cochlea, the fluid within the three compartments causes the …

Basilar Membrane: What Is It? What Are Its Functions ... The basilar membrane is the narrowest (0.08-0.16 mm) and most stiff at the base of the cochlea, and the widest (0.42-0.65 mm) and least stiff at the apex. Note that low-frequency sounds localize near the apex of the cochlea, while high-frequency sounds localize near the base.
