WebThe pinna catches sound waves and channels them down the external auditory canal, where they hit the tympanic membrane and make it vibrate. Those vibrations cause the three ossicles to move. The stapes footplate pushes on the oval window membrane, which sets the cochlear fluid in motion. This wave-like motion causes the basilar membrane to vibrate. WebThe membrane vibrates with opposite phase to vibrations entering the cochlea through the oval window as the fluid in the cochlea is displaced when pressed by the stapes at the oval window. This ensures that hair cells of the basilar membrane will be stimulated and that audition will occur. iowa state cost of crop production
