During sound transduction, sound waves are funneled into the auditory canal and cause vibrations of the eardrum. These vibrations move the ossicles, leading the stapes to press against the oval window of the cochlea. This action causes fluid inside the cochlea to move, enlarging hair cells embedded in the basilar membrane, which then send neural impulses to the brain via the auditory nerve.

Sound transduction is the continuous process where sound waves funneled into the auditory canal cause eardrum vibrations that move the ossicles. The stapes then presses the cochlea's oval window, moving fluid that enlarges hair cells on the basilar membrane, which ultimately send neural impulses to the brain via the auditory nerve.

Conductive hearing loss is a type of auditory impairment characterized by a failure in the transmission of sound energy to the cochlea. This condition specifically involves problems with the mechanical components of the ear, such as a failure in the vibration of the eardrum and/or a failure in the movement of the ossicles.
