This induces an inertia-related phase lag between the ossicles and the surrounding bone, i.e., to motion of the stapes footplate in the oval window, leading to inner ear fluid displacements and pressure differences across the basilar membrane
, and subsequently its displacement and a traveling wave.
Just like sound that comes into the ear from an external source, the cochlear by-product produces its own physical vibration along the basilar membrane
. The DPOAE is generated by the cochlea when the ear is presented with two simultaneous pure tones (f1 and f2).
We should not drill the promontory deeply for cochleostomy and we should not cause possible basilar membrane
damage to avoid pneumolabyrinth.

Jun-Hyuk Kwak, Youngdo Jung, and Kyungjun Song designed the artificial basilar membrane
, performed experiments and analysis, and wrote the manuscript.
The low frequency sound signals cause the basilar membrane
to vibrate with highest oscillation occurring at the apex of the cochlea.
In the scala media, the target site where the OC lies, transplanted mIESCs were found in the lateral wall, basilar membrane
, spiral limbus, and endolymphatic space (Figure 3).
Their basilar membranes
are wider, thinner, and floppier than those of other mammals, which makes them sensitive to low frequencies.
(10) The cochlear hair cells detect displacement of the basilar membrane
and are the weakest link in the transduction of sound energy through the cochlea.
The three fluid spaces (scala media, scala tympani and scala vestibuli) are separated by the two membranes (basilar membrane
and Reissners membrane).
It also indicates that electrical energy converts into sound by a direct effect on the basilar membrane
that then vibrates maximally at a point determined by the frequency, and these vibrations stimulate the hair cells (referred to as electrophonic hearing).
One reason for this is that the basilar membrane
in the cochlea loses some of its elasticity which adversely affects hearing.
