answered-by-expert Expert Answer

(i) Sound travels through our outer ear into a canal which ends with a stretched membrane called eardrum.

(ii) Sound vibrations make the eardrum vibrate.

(iii) The eardrum sends vibrations to the inner ear. From there the signal goes to the brin and that is how we hear.
