I think basilar membrane is the receptors for sounds stimuli.
closest to the cochlea
The eardrum vibrates when sound waves reach it.
That would be the tympanic membrane!!
Typanic membrane
Sound waves→ auricle→ external auditory canal→ tympanic membrane→ malleus→ incus→ stapes→ oval window→ perilymph of the scala vestibuli→ vestibular membrane→ endolymph in the cochlear duct→ basilar membrane →hair cells against tectorial membrane → bending of hair cell stereocilia→ receptor potential→ nerve impulse. Sound wave → scala tympani→ round window.
closest to the cochlea
In general, the cochlea. More specifically, an impulse is carried into the brain along the auditory nerve when the tectorial membrane and the basilar membrane inside the cochlea are pressed together by the force of sound waves.

tympanic membrane
vibrations
That would be the tympanic membrane!!
When the stapes taps on the oval window of the cochlea, it creates waves of pressure within the perilymph. The pressure waves within the perilymph are transferred to the basilar membrane of the organ of corti. The vibrations of the basilar membrane cause the attached hair cells to vibrate against the tectoral membrane. These vibrations are detected by the axons extending from the spiral ganglion in to the spiral lamina, and the impulses are sent to the brain via the cochlear nerve.
Pressure waves (fluctuations) in air.
