Basilar Membrane Vibration in the Gerbil Hemicochlea
Propagation of mechanical disturbances (traveling waves) along the basilar membrane in the cochlea has been studied experimentally for about half a century. As the traveling wave proceeds along the cochlea, from base toward apex, tones of different frequencies produce waves that rise in amplitude at different rates and attain their maxima at different locations before extinguishing.

The Human Ear
Sound waves cause the basilar membrane to move relative to the tectorial membrane. The cilia of the hair cells bend when contact is made to the tectorial membrane and the hair cell discharges. The human cochlea contains approximately 3500 inner hair cells (those lying on the inside of the cochlear coil) and 12,000 outer hair cells (those lying on the outside of the cochlear coil).

The Cochlea
Although the cochlea itself narrows towards the apical end, the basilar membrane has the opposite geometry—becoming wider and more flexible towards the apical end. Primarily because of these physical characteristics, the apical end of the basilar membrane maximally vibrates when exposed to low-frequency sounds, while the narrower, stiffer basal end maximally vibrates when exposed to high

Auditory system
The inner ear consists of the cochlea and several non-auditory structures. The cochlea has three fluid-filled sections (i.e. the scala media, scala tympani and scala vestibuli), and supports a fluid wave driven by pressure across the basilar membrane separating two of the sections. separating two of the sections.

Difference Between Basilar and Tectorial Membrane
The basilar membrane is widest and least stiff at the apex of the cochlea while it is narrowest and stiffest at the base. Different parts of the basilar membrane vibrate in response to sound. And, this is the key to the understanding of cochlear function. What is a

 · Besides the normal hearing pathway known as air conduction (AC), sound can also transmit to the cochlea through the skull, known as bone conduction (BC). During BC stimulation, the cochlear walls demonstrate rigid body motion (RBM) and compressional motion (CPM), both inducing the basilar membrane traveling wave (TW). Despite numerous measuring and modeling efforts for the TW …

Basilar membrane
The basilar membrane is widest (0.42–0.65 mm) and least stiff at the apex of the cochlea, and narrowest (0.08–0.16 mm) and most stiff at the base. High-frequency sounds localize near the base of the cochlea (near the round and oval windows), while low

The basilar membrane (BM), an elastic, ribbon-like structure in the mammalian cochlea, plays a central role in mediating the mechanical decomposition of sound into individual frequency components, a key feature of auditory function.

However, since the cochlea represents a closed hydraulic system with a complex geometry, the motion of the basilar membrane as well as the fluid pressure can hardly be measured. Therefore, a numerical model of the uncoiled cochlea is developed representing the fundamental physical effects occurring in the cochlea.

For example, the BM may fail to provide adequate adhesion between cells of the organ of Corti and the basilar membrane so that basilar membrane motion is not properly tuned by the outer hair cells. Such a hypothesis is consistent with clinical observations that speech discrimination usually remains excellent in Alport syndrome and the SNHL generally does not exceed 60 to 70 dB. 17 , 18
