Quizplus · Accepted Answer

The correct sequence for the processing of sound waves through the ear starts with the pinna (outer ear) capturing the sound, then the sound waves travel through the auditory canal to the eardrum. The vibrations from the eardrum are transmitted through the ossicles (tiny bones in the middle ear), to the cochlea (inner ear), where they are converted into nerve impulses that are sent to the brain via the auditory nerve.
